Next steps

In OpenShift Container Platform version 4.10, you can install a cluster on Google Cloud Platform (GCP) that uses infrastructure that you provide and an internal mirror of the installation release content.

While you can install an OpenShift Container Platform cluster by using mirrored installation release content, your cluster still requires internet access to use the GCP APIs.

The steps for performing a user-provided infrastructure install are outlined here. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods.

The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OpenShift Container Platform. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.

Prerequisites

You reviewed details about the OpenShift Container Platform installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
You created a registry on your mirror host and obtained the imageContentSources data for your version of OpenShift Container Platform.

Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
If you use a firewall, you configured it to allow the sites that your cluster requires access to. While you might need to grant access to more sites, you must grant access to *.googleapis.com and accounts.google.com.
If the cloud identity and access management (IAM) APIs are not accessible in your environment, or if you do not want to store an administrator-level credential secret in the kube-system namespace, you can manually create and maintain IAM credentials.

About installations in restricted networks

In OpenShift Container Platform 4.10, you can perform an installation that does not require an active connection to the internet to obtain software components. Restricted network installations can be completed using installer-provisioned infrastructure or user-provisioned infrastructure, depending on the cloud platform to which you are installing the cluster.

If you choose to perform a restricted network installation on a cloud platform, you still require access to its cloud APIs. Some cloud functions, like Amazon Web Service’s Route 53 DNS and IAM services, require internet access. Depending on your network, you might require less internet access for an installation on bare metal hardware or on VMware vSphere.

To complete a restricted network installation, you must create a registry that mirrors the contents of the OpenShift image registry and contains the installation media. You can create this registry on a mirror host, which can access both the internet and your closed network, or by using other methods that meet your restrictions.

Because of the complexity of the configuration for user-provisioned installations, consider completing a standard user-provisioned infrastructure installation before you attempt a restricted network installation using user-provisioned infrastructure. Completing this test installation might make it easier to isolate and troubleshoot any issues that might arise during your installation in a restricted network.

Additional limits

Clusters in restricted networks have the following additional limitations and restrictions:

The ClusterVersion status includes an Unable to retrieve available updates error.
By default, you cannot use the contents of the Developer Catalog because you cannot access the required image stream tags.

Internet access for OpenShift Container Platform

In OpenShift Container Platform 4.10, you require access to the internet to obtain the images that are necessary to install your cluster.

You must have internet access to:

Access OpenShift Cluster Manager to download the installation program and perform subscription management. If the cluster has internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

If your cluster cannot have direct internet access, you can perform a restricted network installation on some types of infrastructure that you provision. During that process, you download the required content and use it to populate a mirror registry with the installation packages. With some installation types, the environment that you install your cluster in will not require internet access. Before you update the cluster, you update the content of the mirror registry.

Configuring your GCP project

Before you can install OpenShift Container Platform, you must configure a Google Cloud Platform (GCP) project to host it.

Creating a GCP project

To install OpenShift Container Platform, you must create a project in your Google Cloud Platform (GCP) account to host the cluster.

Procedure

Create a project to host your OpenShift Container Platform cluster. See Creating and Managing Projects in the GCP documentation.

Your GCP project must use the Premium Network Service Tier if you are using installer-provisioned infrastructure. The Standard Network Service Tier is not supported for clusters installed using the installation program. The installation program configures internal load balancing for the api-int.<cluster_name>.<base_domain> URL; the Premium Tier is required for internal load balancing.

Enabling API services in GCP

Your Google Cloud Platform (GCP) project requires access to several API services to complete OpenShift Container Platform installation.

Prerequisites

You created a project to host your cluster.

Procedure

Enable the following required API services in the project that hosts your cluster. You can also enable optional API services which are not required for installation. See Enabling services in the GCP documentation.

Table 1. Required API services
API service	Console service name
Compute Engine API	`compute.googleapis.com`
Cloud Resource Manager API	`cloudresourcemanager.googleapis.com`
Google DNS API	`dns.googleapis.com`
IAM Service Account Credentials API	`iamcredentials.googleapis.com`
Identity and Access Management (IAM) API	`iam.googleapis.com`
Service Usage API	`serviceusage.googleapis.com`

Table 2. Optional API services
API service	Console service name
Google Cloud APIs	`cloudapis.googleapis.com`
Service Management API	`servicemanagement.googleapis.com`
Google Cloud Storage JSON API	`storage-api.googleapis.com`
Cloud Storage	`storage-component.googleapis.com`

Configuring DNS for GCP

To install OpenShift Container Platform, the Google Cloud Platform (GCP) account you use must have a dedicated public hosted zone in the same project that you host the OpenShift Container Platform cluster. This zone must be authoritative for the domain. The DNS service provides cluster DNS resolution and name lookup for external connections to the cluster.

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through GCP or another source.

If you purchase a new domain, it can take time for the relevant DNS changes to propagate. For more information about purchasing domains through Google, see Google Domains.
Create a public hosted zone for your domain or subdomain in your GCP project. See Creating public zones in the GCP documentation.

Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
Extract the new authoritative name servers from the hosted zone records. See Look up your Cloud DNS name servers in the GCP documentation.

You typically have four name servers.
Update the registrar records for the name servers that your domain uses. For example, if you registered your domain to Google Domains, see the following topic in the Google Domains Help: How to switch to custom name servers.
If you migrated your root domain to Google Cloud DNS, migrate your DNS records. See Migrating to Cloud DNS in the GCP documentation.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain. This process might include a request to your company’s IT department or the division that controls the root domain and DNS services for your company.

GCP account limits

The OpenShift Container Platform cluster uses a number of Google Cloud Platform (GCP) components, but the default Quotas do not affect your ability to install a default OpenShift Container Platform cluster.

A default cluster, which contains three compute and three control plane machines, uses the following resources. Note that some resources are required only during the bootstrap process and are removed after the cluster deploys.

Table 3. GCP resources used in a default cluster
Service	Component	Location	Total resources required	Resources removed after bootstrap
Service account	IAM	Global	5	0
Firewall rules	Networking	Global	11	1
Forwarding rules	Compute	Global	2	0
Health checks	Compute	Global	2	0
Images	Compute	Global	1	0
Networks	Networking	Global	1	0
Routers	Networking	Global	1	0
Routes	Networking	Global	2	0
Subnetworks	Compute	Global	2	0
Target pools	Networking	Global	2	0

If any of the quotas are insufficient during installation, the installation program displays an error that states both which quota was exceeded and the region.

Be sure to consider your actual cluster size, planned cluster growth, and any usage from other clusters that are associated with your account. The CPU, static IP addresses, and persistent disk SSD (storage) quotas are the ones that are most likely to be insufficient.

If you plan to deploy your cluster in one of the following regions, you will exceed the maximum storage quota and are likely to exceed the CPU quota limit:

asia-east2
asia-northeast2
asia-south1
australia-southeast1
europe-north1
europe-west2
europe-west3
europe-west6
northamerica-northeast1
southamerica-east1
us-west2

You can increase resource quotas from the GCP console, but you might need to file a support ticket. Be sure to plan your cluster size early so that you can allow time to resolve the support ticket before you install your OpenShift Container Platform cluster.

Creating a service account in GCP

OpenShift Container Platform requires a Google Cloud Platform (GCP) service account that provides authentication and authorization to access data in the Google APIs. If you do not have an existing IAM service account that contains the required roles in your project, you must create one.

Prerequisites

You created a project to host your cluster.

Procedure

Create a service account in the project that you use to host your OpenShift Container Platform cluster. See Creating a service account in the GCP documentation.

Grant the service account the appropriate permissions. You can either grant the individual permissions that follow or assign the Owner role to it. See Granting roles to a service account for specific resources.

While making the service account an owner of the project is the easiest way to gain the required permissions, it means that service account has complete control over the project. You must determine if the risk that comes from offering that power is acceptable.

Create the service account key in JSON format. See Creating service account keys in the GCP documentation.

The service account key is required to create a cluster.

Required GCP roles

When you attach the Owner role to the service account that you create, you grant that service account all permissions, including those that are required to install OpenShift Container Platform. If your organization’s security policies require a more restrictive set of permissions, you can create a service account with the following permissions. If you deploy your cluster into an existing virtual private cloud (VPC), the service account does not require certain networking permissions, which are noted in the following lists:

Required roles for the installation program

Compute Admin
Security Admin
Service Account Admin
Service Account Key Admin
Service Account User
Storage Admin

Required roles for creating network resources during installation

DNS Administrator

Required roles for user-provisioned GCP infrastructure

Deployment Manager Editor

The roles are applied to the service accounts that the control plane and compute machines use:

Table 4. GCP service account permissions
Account	Roles
Control Plane	`roles/compute.instanceAdmin`
	`roles/compute.networkAdmin`
	`roles/compute.securityAdmin`
	`roles/storage.admin`
	`roles/iam.serviceAccountUser`
Compute	`roles/compute.viewer`
Compute	`roles/storage.admin`

Required GCP permissions for user-provisioned infrastructure

When you attach the Owner role to the service account that you create, you grant that service account all permissions, including those that are required to install OpenShift Container Platform.

If your organization’s security policies require a more restrictive set of permissions, you can create custom roles with the necessary permissions. The following permissions are required for the user-provisioned infrastructure for creating and deleting the OpenShift Container Platform cluster.

Installing and configuring CLI tools for GCP

To install OpenShift Container Platform on Google Cloud Platform (GCP) using user-provisioned infrastructure, you must install and configure the CLI tools for GCP.

Prerequisites

You created a project to host your cluster.
You created a service account and granted it the required permissions.

Procedure

Install the following binaries in $PATH:
- gcloud
- gsutil
See Install the latest Cloud SDK version in the GCP documentation.
Authenticate using the gcloud tool with your configured service account.

See Authorizing with a service account in the GCP documentation.

Requirements for a cluster with user-provisioned infrastructure

For a cluster that contains user-provisioned infrastructure, you must deploy all of the required machines.

This section describes the requirements for deploying OpenShift Container Platform on user-provisioned infrastructure.

Required machines for cluster installation

The smallest OpenShift Container Platform clusters require the following hosts:

Table 5. Minimum required hosts
Hosts	Description
One temporary bootstrap machine	The cluster requires the bootstrap machine to deploy the OpenShift Container Platform cluster on the three control plane machines. You can remove the bootstrap machine after you install the cluster.
Three control plane machines	The control plane machines run the Kubernetes and OpenShift Container Platform services that form the control plane.
At least two compute machines, which are also known as worker machines.	The workloads requested by OpenShift Container Platform users run on the compute machines.

To maintain high availability of your cluster, use separate physical hosts for these cluster machines.

The bootstrap and control plane machines must use Red Hat Enterprise Linux CoreOS (RHCOS) as the operating system. However, the compute machines can choose between Red Hat Enterprise Linux CoreOS (RHCOS) and Red Hat Enterprise Linux (RHEL) 8.4–8.8.

Note that RHCOS is based on Red Hat Enterprise Linux (RHEL) 8 and inherits all of its hardware certifications and requirements. See Red Hat Enterprise Linux technology capabilities and limits.

Minimum resource requirements for cluster installation

Each cluster machine must meet the following minimum requirements:

Table 6. Minimum resource requirements
Machine	Operating System	vCPU ^[1]	Virtual RAM	Storage	IOPS ^[2]
Bootstrap	RHCOS	4	16 GB	100 GB	300
Control plane	RHCOS	4	16 GB	100 GB	300
Compute	RHCOS, RHEL 8.4–8.8 ^[3]	2	8 GB	100 GB	300

One vCPU is equivalent to one physical core when simultaneous multithreading (SMT), or hyperthreading, is not enabled. When enabled, use the following formula to calculate the corresponding ratio: (threads per core × cores) × sockets = vCPUs.
OpenShift Container Platform and Kubernetes are sensitive to disk performance, and faster storage is recommended, particularly for etcd on the control plane nodes which require a 10 ms p99 fsync duration. Note that on many cloud platforms, storage size and IOPS scale together, so you might need to over-allocate storage volume to obtain sufficient performance.
As with all user-provisioned installations, if you choose to use RHEL compute machines in your cluster, you take responsibility for all operating system life cycle management and maintenance, including performing system updates, applying patches, and completing all other required tasks. Use of RHEL 7 compute machines is deprecated and has been removed in OpenShift Container Platform 4.10 and later.

If an instance type for your platform meets the minimum requirements for cluster machines, it is supported to use in OpenShift Container Platform.

Tested instance types for GCP

The following Google Cloud Platform instance types have been tested with OpenShift Container Platform.

Machine series

C2
C2D
C3
E2
M1
N1
N2
N2D
Tau T2D

Using custom machine types

Using a custom machine type to install a OpenShift Container Platform cluster is supported.

Consider the following when using a custom machine type:

Similar to predefined instance types, custom machine types must meet the minimum resource requirements for control plane and compute machines. For more information, see "Minimum resource requirements for cluster installation".
The name of the custom machine type must adhere to the following syntax:

custom-<number_of_cpus>-<amount_of_memory_in_mb>

For example, custom-6-20480.

Creating the installation files for GCP

To install OpenShift Container Platform on Google Cloud Platform (GCP) using user-provisioned infrastructure, you must generate the files that the installation program needs to deploy your cluster and modify them so that the cluster creates only the machines that it will use. You generate and customize the install-config.yaml file, Kubernetes manifests, and Ignition config files. You also have the option to first set up a separate var partition during the preparation phases of installation.

Optional: Creating a separate `/var` partition

It is recommended that disk partitioning for OpenShift Container Platform be left to the installer. However, there are cases where you might want to create separate partitions in a part of the filesystem that you expect to grow.

OpenShift Container Platform supports the addition of a single partition to attach storage to either the /var partition or a subdirectory of /var. For example:

/var/lib/containers: Holds container-related content that can grow as more images and containers are added to a system.
/var/lib/etcd: Holds data that you might want to keep separate for purposes such as performance optimization of etcd storage.
/var: Holds data that you might want to keep separate for purposes such as auditing.

Storing the contents of a /var directory separately makes it easier to grow storage for those areas as needed and reinstall OpenShift Container Platform at a later date and keep that data intact. With this method, you will not have to pull all your containers again, nor will you have to copy massive log files when you update systems.

Because /var must be in place before a fresh installation of Red Hat Enterprise Linux CoreOS (RHCOS), the following procedure sets up the separate /var partition by creating a machine config manifest that is inserted during the openshift-install preparation phases of an OpenShift Container Platform installation.

If you follow the steps to create a separate /var partition in this procedure, it is not necessary to create the Kubernetes manifest and Ignition config files again as described later in this section.

Procedure

Create a directory to hold the OpenShift Container Platform installation files:
```
$ mkdir $HOME/clusterconfig
```

Run openshift-install to create a set of files in the manifest and openshift subdirectories. Answer the system questions as you are prompted:

$ openshift-install create manifests --dir $HOME/clusterconfig

Example output

? SSH Public Key ...
INFO Credentials loaded from the "myprofile" profile in file "/home/myuser/.aws/credentials"
INFO Consuming Install Config from target directory
INFO Manifests created in: $HOME/clusterconfig/manifests and $HOME/clusterconfig/openshift

Optional: Confirm that the installation program created manifests in the clusterconfig/openshift directory:

$ ls $HOME/clusterconfig/openshift/

Example output

99_kubeadmin-password-secret.yaml
99_openshift-cluster-api_master-machines-0.yaml
99_openshift-cluster-api_master-machines-1.yaml
99_openshift-cluster-api_master-machines-2.yaml
...

Create a Butane config that configures the additional partition. For example, name the file $HOME/clusterconfig/98-var-partition.bu, change the disk device name to the name of the storage device on the worker systems, and set the storage size as appropriate. This example places the /var directory on a separate partition:

variant: openshift
version: 4.10.0
metadata:
  labels:
    machineconfiguration.openshift.io/role: worker
  name: 98-var-partition
storage:
  disks:
  - device: /dev/<device_name> (1)
    partitions:
    - label: var
      start_mib: <partition_start_offset> (2)
      size_mib: <partition_size> (3)
  filesystems:
    - device: /dev/disk/by-partlabel/var
      path: /var
      format: xfs
      mount_options: [defaults, prjquota] (4)
      with_mount_unit: true

1	The storage device name of the disk that you want to partition.
2	When adding a data partition to the boot disk, a minimum value of 25000 MiB (Mebibytes) is recommended. The root file system is automatically resized to fill all available space up to the specified offset. If no value is specified, or if the specified value is smaller than the recommended minimum, the resulting root file system will be too small, and future reinstalls of RHCOS might overwrite the beginning of the data partition.
3	The size of the data partition in mebibytes.
4	The `prjquota` mount option must be enabled for filesystems used for container storage.

When creating a separate /var partition, you cannot use different instance types for worker nodes, if the different instance types do not have the same device name.

Create a manifest from the Butane config and save it to the clusterconfig/openshift directory. For example, run the following command:
```
$ butane $HOME/clusterconfig/98-var-partition.bu -o $HOME/clusterconfig/openshift/98-var-partition.yaml
```

Run openshift-install again to create Ignition configs from a set of files in the manifest and openshift subdirectories:

$ openshift-install create ignition-configs --dir $HOME/clusterconfig
$ ls $HOME/clusterconfig/
auth  bootstrap.ign  master.ign  metadata.json  worker.ign

Now you can use the Ignition config files as input to the installation procedures to install Red Hat Enterprise Linux CoreOS (RHCOS) systems.

Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your mirror host.
Have the imageContentSources values that were generated during mirror registry creation.
Obtain the contents of the certificate for your mirror registry.
Obtain service principal permissions at the subscription level.

Procedure

Create the install-config.yaml file.

Change to the directory that contains the installation program and run the following command:

$ ./openshift-install create install-config --dir <installation_directory> (1)

1	For `<installation_directory>`, specify the directory name to store the files that the installation program creates.

Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.

At the prompts, provide the configuration details for your cloud:
1. Optional: Select an SSH key to use to access your cluster machines.
  
  For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
2. Select gcp as the platform to target.
3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
5. Select the region to deploy the cluster to.
6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
7. Enter a descriptive name for your cluster.
8. Paste the pull secret from the Red Hat OpenShift Cluster Manager.

Edit the install-config.yaml file to give the additional information that is required for an installation in a restricted network.
1. Update the pullSecret value to contain the authentication information for your registry:
  pullSecret: '{"auths":{"<mirror_host_name>:5000": {"auth": "<credentials>","email": "you@example.com"}}}'
  For <mirror_host_name>, specify the registry domain name that you specified in the certificate for your mirror registry, and for <credentials>, specify the base64-encoded user name and password for your mirror registry.
2. Add the additionalTrustBundle parameter and value.
  additionalTrustBundle: | -----BEGIN CERTIFICATE----- ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ -----END CERTIFICATE-----
  The value must be the contents of the certificate file that you used for your mirror registry. The certificate file can be an existing, trusted certificate authority, or the self-signed certificate that you generated for the mirror registry.
3. Define the network and subnets for the VPC to install the cluster in under the parent platform.gcp field:
  network: <existing_vpc> controlPlaneSubnet: <control_plane_subnet> computeSubnet: <compute_subnet>
  For platform.gcp.network, specify the name for the existing Google VPC. For platform.gcp.controlPlaneSubnet and platform.gcp.computeSubnet, specify the existing subnets to deploy the control plane machines and compute machines, respectively.
4. Add the image content resources, which resemble the following YAML excerpt:
  imageContentSources: - mirrors: - <mirror_host_name>:5000/<repo_name>/release source: quay.io/openshift-release-dev/ocp-release - mirrors: - <mirror_host_name>:5000/<repo_name>/release source: registry.redhat.io/ocp/release
  For these values, use the imageContentSources that you recorded during mirror registry creation.
Make any other modifications to the install-config.yaml file that you require. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.

The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

Configuring the cluster-wide proxy during installation

Production environments can deny direct access to the internet and instead have an HTTP or HTTPS proxy available. You can configure a new OpenShift Container Platform cluster to use a proxy by configuring the proxy settings in the install-config.yaml file.

Prerequisites

You have an existing install-config.yaml file.

You reviewed the sites that your cluster requires access to and determined whether any of them need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. You added sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.

The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.

For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:

apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> (1)
  httpsProxy: https://<username>:<pswd>@<ip>:<port> (2)
  noProxy: example.com (3)
additionalTrustBundle: | (4)
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...

1	A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be `http`.
2	A proxy URL to use for creating HTTPS connections outside the cluster.
3	A comma-separated list of destination domain names, IP addresses, or other network CIDRs to exclude from proxying. Preface a domain with `.` to match subdomains only. For example, `.y.com` matches `x.y.com`, but not `y.com`. Use `*` to bypass the proxy for all destinations.
4	If provided, the installation program generates a config map that is named `user-ca-bundle` in the `openshift-config` namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a `trusted-ca-bundle` config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the `trustedCA` field of the `Proxy` object. The `additionalTrustBundle` field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle.

The installation program does not support the proxy readinessEndpoints field.

If the installer times out, restart and then complete the deployment by using the wait-for command of the installer. For example:

$ ./openshift-install wait-for install-complete --log-level debug

Save the file and reference it when installing OpenShift Container Platform.

The installation program creates a cluster-wide proxy that is named cluster that uses the proxy settings in the provided install-config.yaml file. If no proxy settings are provided, a cluster Proxy object is still created, but it will have a nil spec.

Only the Proxy object named cluster is supported, and no additional proxies can be created.

Creating the Kubernetes manifest and Ignition config files

Because you must modify some cluster definition files and manually start the cluster machines, you must generate the Kubernetes manifest and Ignition config files that the cluster needs to configure the machines.

The installation configuration file transforms into the Kubernetes manifests. The manifests wrap into the Ignition configuration files, which are later used to configure the cluster machines.

The Ignition config files that the OpenShift Container Platform installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
It is recommended that you use Ignition config files within 12 hours after they are generated because the 24-hour certificate rotates from 16 to 22 hours after the cluster is installed. By using the Ignition config files within 12 hours, you can avoid installation failure if the certificate update runs during installation.

Prerequisites

You obtained the OpenShift Container Platform installation program. For a restricted network installation, these files are on your mirror host.
You created the install-config.yaml installation configuration file.

Procedure

Change to the directory that contains the OpenShift Container Platform installation program and generate the Kubernetes manifests for the cluster:
```
$ ./openshift-install create manifests --dir <installation_directory> (1)
```
1 For <installation_directory>, specify the installation directory that contains the install-config.yaml file you created.
Remove the Kubernetes manifest files that define the control plane machines:
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
By removing these files, you prevent the cluster from automatically generating control plane machines.
Optional: If you do not want the cluster to provision compute machines, remove the Kubernetes manifest files that define the worker machines:
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Check that the mastersSchedulable parameter in the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file is set to false. This setting prevents pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and ensure that it is set to false.
3. Save and exit the file.
Optional: If you do not want the Ingress Operator to create DNS records on your behalf, remove the privateZone and publicZone sections from the <installation_directory>/manifests/cluster-dns-02-config.yml DNS configuration file:
```
apiVersion: config.openshift.io/v1
kind: DNS
metadata:
  creationTimestamp: null
  name: cluster
spec:
  baseDomain: example.openshift.com
  privateZone: (1)
    id: mycluster-100419-private-zone
  publicZone: (1)
    id: example.openshift.com
status: {}
```
1 Remove this section completely.

If you do so, you must add ingress DNS records manually in a later step.
To create the Ignition configuration files, run the following command from the directory that contains the installation program:
```
$ ./openshift-install create ignition-configs --dir <installation_directory> (1)
```
1 For <installation_directory>, specify the same installation directory.

Ignition config files are created for the bootstrap, control plane, and compute nodes in the installation directory. The kubeadmin-password and kubeconfig files are created in the ./<installation_directory>/auth directory:
```
.
├── auth
│   ├── kubeadmin-password
│   └── kubeconfig
├── bootstrap.ign
├── master.ign
├── metadata.json
└── worker.ign
```

Additional resources

Optional: Adding the ingress DNS records

Exporting common variables

Extracting the infrastructure name

The Ignition config files contain a unique cluster identifier that you can use to uniquely identify your cluster in Google Cloud Platform (GCP). The infrastructure name is also used to locate the appropriate GCP resources during an OpenShift Container Platform installation. The provided Deployment Manager templates contain references to this infrastructure name, so you must extract it.

Prerequisites

You obtained the OpenShift Container Platform installation program and the pull secret for your cluster.
You generated the Ignition config files for your cluster.
You installed the jq package.

Procedure

To extract and view the infrastructure name from the Ignition config file metadata, run the following command:
```
$ jq -r .infraID <installation_directory>/metadata.json (1)
```
1 For <installation_directory>, specify the path to the directory that you stored the installation files in.
Example output
```
openshift-vw9j6 (1)
```
1 The output of this command is your cluster name and a random string.

Exporting common variables for Deployment Manager templates

You must export a common set of variables that are used with the provided Deployment Manager templates used to assist in completing a user-provided infrastructure install on Google Cloud Platform (GCP).

Specific Deployment Manager templates can also require additional exported variables, which are detailed in their related procedures.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.
Generate the Ignition config files for your cluster.
Install the jq package.

Procedure

Export the following common variables to be used by the provided Deployment Manager templates:

$ export BASE_DOMAIN='<base_domain>'
$ export BASE_DOMAIN_ZONE_NAME='<base_domain_zone_name>'
$ export NETWORK_CIDR='10.0.0.0/16'
$ export MASTER_SUBNET_CIDR='10.0.0.0/17'
$ export WORKER_SUBNET_CIDR='10.0.128.0/17'

$ export KUBECONFIG=<installation_directory>/auth/kubeconfig (1)
$ export CLUSTER_NAME=`jq -r .clusterName <installation_directory>/metadata.json`
$ export INFRA_ID=`jq -r .infraID <installation_directory>/metadata.json`
$ export PROJECT_NAME=`jq -r .gcp.projectID <installation_directory>/metadata.json`
$ export REGION=`jq -r .gcp.region <installation_directory>/metadata.json`

1	For `<installation_directory>`, specify the path to the directory that you stored the installation files in.

Creating a VPC in GCP

You must create a VPC in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. You can customize the VPC to meet your requirements. One way to create the VPC is to modify the provided Deployment Manager template.

If you do not use the provided Deployment Manager template to create your GCP infrastructure, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.

Procedure

Copy the template from the Deployment Manager template for the VPC section of this topic and save it as 01_vpc.py on your computer. This template describes the VPC that your cluster requires.

Create a 01_vpc.yaml resource definition file:

$ cat <<EOF >01_vpc.yaml
imports:
- path: 01_vpc.py

resources:
- name: cluster-vpc
  type: 01_vpc.py
  properties:
    infra_id: '${INFRA_ID}' (1)
    region: '${REGION}' (2)
    master_subnet_cidr: '${MASTER_SUBNET_CIDR}' (3)
    worker_subnet_cidr: '${WORKER_SUBNET_CIDR}' (4)
EOF

1	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
2	`region` is the region to deploy the cluster into, for example `us-central1`.
3	`master_subnet_cidr` is the CIDR for the master subnet, for example `10.0.0.0/17`.
4	`worker_subnet_cidr` is the CIDR for the worker subnet, for example `10.0.128.0/17`.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-vpc --config 01_vpc.yaml

Deployment Manager template for the VPC

You can use the following Deployment Manager template to deploy the VPC that you need for your OpenShift Container Platform cluster:

01_vpc.py Deployment Manager template

                }]
            }, {

                }]
            }]
        }
    }]

    return {'resources': resources}

Networking requirements for user-provisioned infrastructure

All the Red Hat Enterprise Linux CoreOS (RHCOS) machines require networking to be configured in initramfs during boot to fetch their Ignition config files.

Setting the cluster node hostnames through DHCP

On Red Hat Enterprise Linux CoreOS (RHCOS) machines, the hostname is set through NetworkManager. By default, the machines obtain their hostname through DHCP. If the hostname is not provided by DHCP, set statically through kernel arguments, or another method, it is obtained through a reverse DNS lookup. Reverse DNS lookup occurs after the network has been initialized on a node and can take time to resolve. Other system services can start prior to this and detect the hostname as localhost or similar. You can avoid this by using DHCP to provide the hostname for each cluster node.

Additionally, setting the hostnames through DHCP can bypass any manual DNS record name configuration errors in environments that have a DNS split-horizon implementation.

Network connectivity requirements

You must configure the network connectivity between machines to allow OpenShift Container Platform cluster components to communicate. Each machine must be able to resolve the hostnames of all other machines in the cluster.

This section provides details about the ports that are required.

Creating load balancers in GCP

You must configure load balancers in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Deployment Manager template.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for the internal load balancer section of this topic and save it as 02_lb_int.py on your computer. This template describes the internal load balancing objects that your cluster requires.
For an external cluster, also copy the template from the Deployment Manager template for the external load balancer section of this topic and save it as 02_lb_ext.py on your computer. This template describes the external load balancing objects that your cluster requires.

Export the variables that the deployment template uses:

Export the cluster network location:

$ export CLUSTER_NETWORK=(`gcloud compute networks describe ${INFRA_ID}-network --format json | jq -r .selfLink`)

Export the control plane subnet location:

$ export CONTROL_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-master-subnet --region=${REGION} --format json | jq -r .selfLink`)

Export the three zones that the cluster uses:

$ export ZONE_0=(`gcloud compute regions describe ${REGION} --format=json | jq -r .zones[0] | cut -d "/" -f9`)

$ export ZONE_1=(`gcloud compute regions describe ${REGION} --format=json | jq -r .zones[1] | cut -d "/" -f9`)

$ export ZONE_2=(`gcloud compute regions describe ${REGION} --format=json | jq -r .zones[2] | cut -d "/" -f9`)

Create a 02_infra.yaml resource definition file:

$ cat <<EOF >02_infra.yaml
imports:
- path: 02_lb_ext.py
- path: 02_lb_int.py (1)
resources:
- name: cluster-lb-ext (1)
  type: 02_lb_ext.py
  properties:
    infra_id: '${INFRA_ID}' (2)
    region: '${REGION}' (3)
- name: cluster-lb-int
  type: 02_lb_int.py
  properties:
    cluster_network: '${CLUSTER_NETWORK}'
    control_subnet: '${CONTROL_SUBNET}' (4)
    infra_id: '${INFRA_ID}'
    region: '${REGION}'
    zones: (5)
    - '${ZONE_0}'
    - '${ZONE_1}'
    - '${ZONE_2}'
EOF

1	Required only when deploying an external cluster.
2	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
3	`region` is the region to deploy the cluster into, for example `us-central1`.
4	`control_subnet` is the URI to the control subnet.
5	`zones` are the zones to deploy the control plane instances into, like `us-east1-b`, `us-east1-c`, and `us-east1-d`.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-infra --config 02_infra.yaml

Export the cluster IP address:

$ export CLUSTER_IP=(`gcloud compute addresses describe ${INFRA_ID}-cluster-ip --region=${REGION} --format json | jq -r .address`)

For an external cluster, also export the cluster public IP address:

$ export CLUSTER_PUBLIC_IP=(`gcloud compute addresses describe ${INFRA_ID}-cluster-public-ip --region=${REGION} --format json | jq -r .address`)

Deployment Manager template for the external load balancer

You can use the following Deployment Manager template to deploy the external load balancer that you need for your OpenShift Container Platform cluster:

You will need this template in addition to the 02_lb_ext.py template when you create an external cluster.

Creating a private DNS zone in GCP

You must configure a private DNS zone in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create this component is to modify the provided Deployment Manager template.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for the private DNS section of this topic and save it as 02_dns.py on your computer. This template describes the private DNS objects that your cluster requires.

Create a 02_dns.yaml resource definition file:

$ cat <<EOF >02_dns.yaml
imports:
- path: 02_dns.py

resources:
- name: cluster-dns
  type: 02_dns.py
  properties:
    infra_id: '${INFRA_ID}' (1)
    cluster_domain: '${CLUSTER_NAME}.${BASE_DOMAIN}' (2)
    cluster_network: '${CLUSTER_NETWORK}' (3)
EOF

1	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
2	`cluster_domain` is the domain for the cluster, for example `openshift.example.com`.
3	`cluster_network` is the `selfLink` URL to the cluster network.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-dns --config 02_dns.yaml

The templates do not create DNS entries due to limitations of Deployment Manager, so you must create them manually:

Add the internal DNS entries:

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction add ${CLUSTER_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction add ${CLUSTER_IP} --name api-int.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone

For an external cluster, also add the external DNS entries:

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction add ${CLUSTER_PUBLIC_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

Deployment Manager template for the private DNS

You can use the following Deployment Manager template to deploy the private DNS that you need for your OpenShift Container Platform cluster:

02_dns.py Deployment Manager template

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-private-zone',
        'type': 'dns.v1.managedZone',
        'properties': {
            'description': '',
            'dnsName': context.properties['cluster_domain'] + '.',
            'visibility': 'private',
            'privateVisibilityConfig': {
                'networks': [{
                    'networkUrl': context.properties['cluster_network']
                }]
            }
        }
    }]

    return {'resources': resources}

Creating firewall rules in GCP

You must create firewall rules in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Deployment Manager template.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for firewall rules section of this topic and save it as 03_firewall.py on your computer. This template describes the security groups that your cluster requires.

Create a 03_firewall.yaml resource definition file:

$ cat <<EOF >03_firewall.yaml
imports:
- path: 03_firewall.py

resources:
- name: cluster-firewall
  type: 03_firewall.py
  properties:
    allowed_external_cidr: '0.0.0.0/0' (1)
    infra_id: '${INFRA_ID}' (2)
    cluster_network: '${CLUSTER_NETWORK}' (3)
    network_cidr: '${NETWORK_CIDR}' (4)
EOF

1	`allowed_external_cidr` is the CIDR range that can access the cluster API and SSH to the bootstrap host. For an internal cluster, set this value to `${NETWORK_CIDR}`.
2	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
3	`cluster_network` is the `selfLink` URL to the cluster network.
4	`network_cidr` is the CIDR of the VPC network, for example `10.0.0.0/16`.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-firewall --config 03_firewall.yaml

Deployment Manager template for firewall rules

You can use the following Deployment Manager template to deploy the firewall rues that you need for your OpenShift Container Platform cluster:

03_firewall.py Deployment Manager template

Creating IAM roles in GCP

You must create IAM roles in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Deployment Manager template.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for IAM roles section of this topic and save it as 03_iam.py on your computer. This template describes the IAM roles that your cluster requires.

Create a 03_iam.yaml resource definition file:

$ cat <<EOF >03_iam.yaml
imports:
- path: 03_iam.py
resources:
- name: cluster-iam
  type: 03_iam.py
  properties:
    infra_id: '${INFRA_ID}' (1)
EOF

1	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-iam --config 03_iam.yaml

Export the variable for the master service account:

$ export MASTER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-m@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Export the variable for the worker service account:

$ export WORKER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-w@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Export the variable for the subnet that hosts the compute machines:

$ export COMPUTE_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-worker-subnet --region=${REGION} --format json | jq -r .selfLink`)

The templates do not create the policy bindings due to limitations of Deployment Manager, so you must create them manually:

$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.instanceAdmin"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkAdmin"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.securityAdmin"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/iam.serviceAccountUser"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/storage.admin"

$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/compute.viewer"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/storage.admin"

Create a service account key and store it locally for later use:

$ gcloud iam service-accounts keys create service-account-key.json --iam-account=${MASTER_SERVICE_ACCOUNT}

Deployment Manager template for IAM roles

You can use the following Deployment Manager template to deploy the IAM roles that you need for your OpenShift Container Platform cluster:

03_iam.py Deployment Manager template

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-master-node-sa',
        'type': 'iam.v1.serviceAccount',
        'properties': {
            'accountId': context.properties['infra_id'] + '-m',
            'displayName': context.properties['infra_id'] + '-master-node'
        }
    }, {
        'name': context.properties['infra_id'] + '-worker-node-sa',
        'type': 'iam.v1.serviceAccount',
        'properties': {
            'accountId': context.properties['infra_id'] + '-w',
            'displayName': context.properties['infra_id'] + '-worker-node'
        }
    }]

    return {'resources': resources}

Creating the RHCOS cluster image for the GCP infrastructure

You must use a valid Red Hat Enterprise Linux CoreOS (RHCOS) image for Google Cloud Platform (GCP) for your OpenShift Container Platform nodes.

Procedure

Obtain the RHCOS image from the RHCOS image mirror page.

The RHCOS images might not change with every release of OpenShift Container Platform. You must download an image with the highest version that is less than or equal to the OpenShift Container Platform version that you install. Use the image version that matches your OpenShift Container Platform version if it is available.

The file name contains the OpenShift Container Platform version number in the format rhcos-<version>-<arch>-gcp.<arch>.tar.gz.

Create the Google storage bucket:
```
$ gsutil mb gs://<bucket_name>
```

Upload the RHCOS image to the Google storage bucket:

$ gsutil cp <downloaded_image_file_path>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz  gs://<bucket_name>

Export the uploaded RHCOS image location as a variable:

$ export IMAGE_SOURCE=gs://<bucket_name>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz

Create the cluster image:

$ gcloud compute images create "${INFRA_ID}-rhcos-image" \
    --source-uri="${IMAGE_SOURCE}"

Creating the bootstrap machine in GCP

You must create the bootstrap machine in Google Cloud Platform (GCP) to use during OpenShift Container Platform cluster initialization. One way to create this machine is to modify the provided Deployment Manager template.

If you do not use the provided Deployment Manager template to create your bootstrap machine, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Ensure pyOpenSSL is installed.

Procedure

Copy the template from the Deployment Manager template for the bootstrap machine section of this topic and save it as 04_bootstrap.py on your computer. This template describes the bootstrap machine that your cluster requires.

Export the location of the Red Hat Enterprise Linux CoreOS (RHCOS) image that the installation program requires:

$ export CLUSTER_IMAGE=(`gcloud compute images describe ${INFRA_ID}-rhcos-image --format json | jq -r .selfLink`)

Create a bucket and upload the bootstrap.ign file:

$ gsutil mb gs://${INFRA_ID}-bootstrap-ignition

$ gsutil cp <installation_directory>/bootstrap.ign gs://${INFRA_ID}-bootstrap-ignition/

Create a signed URL for the bootstrap instance to use to access the Ignition config. Export the URL from the output as a variable:

$ export BOOTSTRAP_IGN=`gsutil signurl -d 1h service-account-key.json gs://${INFRA_ID}-bootstrap-ignition/bootstrap.ign | grep "^gs:" | awk '{print $5}'`

Create a 04_bootstrap.yaml resource definition file:

$ cat <<EOF >04_bootstrap.yaml
imports:
- path: 04_bootstrap.py

resources:
- name: cluster-bootstrap
  type: 04_bootstrap.py
  properties:
    infra_id: '${INFRA_ID}' (1)
    region: '${REGION}' (2)
    zone: '${ZONE_0}' (3)

    cluster_network: '${CLUSTER_NETWORK}' (4)
    control_subnet: '${CONTROL_SUBNET}' (5)
    image: '${CLUSTER_IMAGE}' (6)
    machine_type: 'n1-standard-4' (7)
    root_volume_size: '128' (8)

    bootstrap_ign: '${BOOTSTRAP_IGN}' (9)
EOF

1	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
2	`region` is the region to deploy the cluster into, for example `us-central1`.
3	`zone` is the zone to deploy the bootstrap instance into, for example `us-central1-b`.
4	`cluster_network` is the `selfLink` URL to the cluster network.
5	`control_subnet` is the `selfLink` URL to the control subnet.
6	`image` is the `selfLink` URL to the RHCOS image.
7	`machine_type` is the machine type of the instance, for example `n1-standard-4`.
8	`root_volume_size` is the boot disk size for the bootstrap machine.
9	`bootstrap_ign` is the URL output when creating a signed URL.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-bootstrap --config 04_bootstrap.yaml

The templates do not manage load balancer membership due to limitations of Deployment Manager, so you must add the bootstrap machine manually.

Add the bootstrap instance to the internal load balancer instance group:

$ gcloud compute instance-groups unmanaged add-instances \
    ${INFRA_ID}-bootstrap-ig --zone=${ZONE_0} --instances=${INFRA_ID}-bootstrap

Add the bootstrap instance group to the internal load balancer backend service:

$ gcloud compute backend-services add-backend \
    ${INFRA_ID}-api-internal-backend-service --region=${REGION} --instance-group=${INFRA_ID}-bootstrap-ig --instance-group-zone=${ZONE_0}

Deployment Manager template for the bootstrap machine

You can use the following Deployment Manager template to deploy the bootstrap machine that you need for your OpenShift Container Platform cluster:

04_bootstrap.py Deployment Manager template

Creating the control plane machines in GCP

You must create the control plane machines in Google Cloud Platform (GCP) for your cluster to use. One way to create these machines is to modify the provided Deployment Manager template.

If you do not use the provided Deployment Manager template to create your control plane machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.

Procedure

Copy the template from the Deployment Manager template for control plane machines section of this topic and save it as 05_control_plane.py on your computer. This template describes the control plane machines that your cluster requires.

Export the following variable required by the resource definition:

$ export MASTER_IGNITION=`cat <installation_directory>/master.ign`

Create a 05_control_plane.yaml resource definition file:

$ cat <<EOF >05_control_plane.yaml
imports:
- path: 05_control_plane.py

resources:
- name: cluster-control-plane
  type: 05_control_plane.py
  properties:
    infra_id: '${INFRA_ID}' (1)
    zones: (2)
    - '${ZONE_0}'
    - '${ZONE_1}'
    - '${ZONE_2}'

    control_subnet: '${CONTROL_SUBNET}' (3)
    image: '${CLUSTER_IMAGE}' (4)
    machine_type: 'n1-standard-4' (5)
    root_volume_size: '128'
    service_account_email: '${MASTER_SERVICE_ACCOUNT}' (6)

    ignition: '${MASTER_IGNITION}' (7)
EOF

1	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
2	`zones` are the zones to deploy the control plane instances into, for example `us-central1-a`, `us-central1-b`, and `us-central1-c`.
3	`control_subnet` is the `selfLink` URL to the control subnet.
4	`image` is the `selfLink` URL to the RHCOS image.
5	`machine_type` is the machine type of the instance, for example `n1-standard-4`.
6	`service_account_email` is the email address for the master service account that you created.
7	`ignition` is the contents of the `master.ign` file.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-control-plane --config 05_control_plane.yaml

The templates do not manage load balancer membership due to limitations of Deployment Manager, so you must add the control plane machines manually.

Run the following commands to add the control plane machines to the appropriate instance groups:

$ gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_0}-ig --zone=${ZONE_0} --instances=${INFRA_ID}-master-0

$ gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_1}-ig --zone=${ZONE_1} --instances=${INFRA_ID}-master-1

$ gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_2}-ig --zone=${ZONE_2} --instances=${INFRA_ID}-master-2

For an external cluster, you must also run the following commands to add the control plane machines to the target pools:

$ gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_0}" --instances=${INFRA_ID}-master-0

$ gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_1}" --instances=${INFRA_ID}-master-1

$ gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_2}" --instances=${INFRA_ID}-master-2

Deployment Manager template for control plane machines

You can use the following Deployment Manager template to deploy the control plane machines that you need for your OpenShift Container Platform cluster:

Wait for bootstrap completion and remove bootstrap resources in GCP

After you create all of the required infrastructure in Google Cloud Platform (GCP), wait for the bootstrap process to complete on the machines that you provisioned by using the Ignition config files that you generated with the installation program.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Change to the directory that contains the installation program and run the following command:

$ ./openshift-install wait-for bootstrap-complete --dir <installation_directory> \ (1)
    --log-level info (2)

1	For `<installation_directory>`, specify the path to the directory that you stored the installation files in.
2	To view different installation details, specify `warn`, `debug`, or `error` instead of `info`.

If the command exits without a FATAL warning, your production control plane has initialized.

Delete the bootstrap resources:

$ gcloud compute backend-services remove-backend ${INFRA_ID}-api-internal-backend-service --region=${REGION} --instance-group=${INFRA_ID}-bootstrap-ig --instance-group-zone=${ZONE_0}

$ gsutil rm gs://${INFRA_ID}-bootstrap-ignition/bootstrap.ign

$ gsutil rb gs://${INFRA_ID}-bootstrap-ignition

$ gcloud deployment-manager deployments delete ${INFRA_ID}-bootstrap

Creating additional worker machines in GCP

You can create worker machines in Google Cloud Platform (GCP) for your cluster to use by launching individual instances discretely or by automated processes outside the cluster, such as auto scaling groups. You can also take advantage of the built-in cluster scaling mechanisms and the machine API in OpenShift Container Platform.

In this example, you manually launch one instance by using the Deployment Manager template. Additional instances can be launched by including additional resources of type 06_worker.py in the file.

If you do not use the provided Deployment Manager template to create your worker machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Copy the template from the Deployment Manager template for worker machines section of this topic and save it as 06_worker.py on your computer. This template describes the worker machines that your cluster requires.

Export the variables that the resource definition uses.

Export the subnet that hosts the compute machines:

$ export COMPUTE_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-worker-subnet --region=${REGION} --format json | jq -r .selfLink`)

Export the email address for your service account:

$ export WORKER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-w@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Export the location of the compute machine Ignition config file:

$ export WORKER_IGNITION=`cat <installation_directory>/worker.ign`

Create a 06_worker.yaml resource definition file:

$ cat <<EOF >06_worker.yaml
imports:
- path: 06_worker.py

resources:
- name: 'worker-0' (1)
  type: 06_worker.py
  properties:

    root_volume_size: '128'
    service_account_email: '${WORKER_SERVICE_ACCOUNT}' (7)
    ignition: '${WORKER_IGNITION}' (8)
EOF

1	`name` is the name of the worker machine, for example `worker-0`.
2	`infra_id` is the `INFRA_ID` infrastructure name from the extraction step.
3	`zone` is the zone to deploy the worker machine into, for example `us-central1-a`.
4	`compute_subnet` is the `selfLink` URL to the compute subnet.
5	`image` is the `selfLink` URL to the RHCOS image. ¹
6	`machine_type` is the machine type of the instance, for example `n1-standard-4`.
7	`service_account_email` is the email address for the worker service account that you created.
8	`ignition` is the contents of the `worker.ign` file.

Optional: If you want to launch additional instances, include additional resources of type 06_worker.py in your 06_worker.yaml resource definition file.

Create the deployment by using the gcloud CLI:

$ gcloud deployment-manager deployments create ${INFRA_ID}-worker --config 06_worker.yaml

Deployment Manager template for worker machines

You can use the following Deployment Manager template to deploy the worker machines that you need for your OpenShift Container Platform cluster:

06_worker.py Deployment Manager template

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-' + context.env['name'],
        'type': 'compute.v1.instance',
        'properties': {
            'disks': [{
                'autoDelete': True,
                'boot': True,
                'initializeParams': {
                    'diskSizeGb': context.properties['root_volume_size'],
                    'sourceImage': context.properties['image']
                }
            }],
            'machineType': 'zones/' + context.properties['zone'] + '/machineTypes/' + context.properties['machine_type'],
            'metadata': {
                'items': [{
                    'key': 'user-data',
                    'value': context.properties['ignition']
                }]
            },
            'networkInterfaces': [{
                'subnetwork': context.properties['compute_subnet']
            }],
            'serviceAccounts': [{
                'email': context.properties['service_account_email'],
                'scopes': ['https://www.googleapis.com/auth/cloud-platform']
            }],
            'tags': {
                'items': [
                    context.properties['infra_id'] + '-worker',
                ]
            },
            'zone': context.properties['zone']
        }
    }]

    return {'resources': resources}

Logging in to the cluster by using the CLI

You can log in to your cluster as a default system user by exporting the cluster kubeconfig file. The kubeconfig file contains information about the cluster that is used by the CLI to connect a client to the correct cluster and API server. The file is specific to a cluster and is created during OpenShift Container Platform installation.

Prerequisites

You deployed an OpenShift Container Platform cluster.
You installed the oc CLI.

Procedure

Export the kubeadmin credentials:
```
$ export KUBECONFIG=<installation_directory>/auth/kubeconfig (1)
```
1 For <installation_directory>, specify the path to the directory that you stored the installation files in.
Verify you can run oc commands successfully using the exported configuration:
```
$ oc whoami
```
Example output
```
system:admin
```

Disabling the default OperatorHub sources

Operator catalogs that source content provided by Red Hat and community projects are configured for OperatorHub by default during an OpenShift Container Platform installation. In a restricted network environment, you must disable the default catalogs as a cluster administrator.

Procedure

Disable the sources for the default catalogs by adding disableAllDefaultSources: true to the OperatorHub object:

$ oc patch OperatorHub cluster --type json \
    -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]'

Alternatively, you can use the web console to manage catalog sources. From the Administration → Cluster Settings → Configuration → OperatorHub page, click the Sources tab, where you can create, delete, disable, and enable individual sources.

Approving the certificate signing requests for your machines

When you add machines to a cluster, two pending certificate signing requests (CSRs) are generated for each machine that you added. You must confirm that these CSRs are approved or, if necessary, approve them yourself. The client requests must be approved first, followed by the server requests.

Prerequisites

You added machines to your cluster.

Procedure

Confirm that the cluster recognizes the machines:
```
$ oc get nodes
```
Example output
```
NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.23.0
master-1  Ready     master  63m  v1.23.0
master-2  Ready     master  64m  v1.23.0
```
The output lists all of the machines that you created.

The preceding output might not include the compute nodes, also known as worker nodes, until some CSRs are approved.

Review the pending CSRs and ensure that you see the client requests with the Pending or Approved status for each machine that you added to the cluster:

$ oc get csr

Example output

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

In this example, two machines are joining the cluster. You might see more approved CSRs in the list.

If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending status, approve the CSRs for your cluster machines:

Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. After the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the machine-approver if the Kubelet requests a new certificate with identical parameters.

For clusters running on platforms that are not machine API enabled, such as bare metal and other user-provisioned infrastructure, you must implement a method of automatically approving the kubelet serving certificate requests (CSRs). If a request is not approved, then the oc exec, oc rsh, and oc logs commands cannot succeed, because a serving certificate is required when the API server connects to the kubelet. Any operation that contacts the Kubelet endpoint requires this certificate approval to be in place. The method must watch for new CSRs, confirm that the CSR was submitted by the node-bootstrapper service account in the system:node or system:admin groups, and confirm the identity of the node.

To approve them individually, run the following command for each valid CSR:
```
$ oc adm certificate approve <csr_name> (1)
```
1 <csr_name> is the name of a CSR from the list of current CSRs.

To approve all pending CSRs, run the following command:

$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve

Some Operators might not become available until some CSRs are approved.

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:

$ oc get csr

Example output

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-bfd72   5m26s   system:node:ip-10-0-50-126.us-east-2.compute.internal                       Pending
csr-c57lv   5m26s   system:node:ip-10-0-95-157.us-east-2.compute.internal                       Pending
...

If the remaining CSRs are not approved, and are in the Pending status, approve the CSRs for your cluster machines:
- To approve them individually, run the following command for each valid CSR:
  $ oc adm certificate approve <csr_name> (1)
  1 <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  $ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve

After all client and server CSRs have been approved, the machines have the Ready status. Verify this by running the following command:

$ oc get nodes

Example output

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  73m  v1.23.0
master-1  Ready     master  73m  v1.23.0
master-2  Ready     master  74m  v1.23.0
worker-0  Ready     worker  11m  v1.23.0
worker-1  Ready     worker  11m  v1.23.0

It can take a few minutes after approval of the server CSRs for the machines to transition to the Ready status.

Additional information

For more information on CSRs, see Certificate Signing Requests.

Optional: Adding the ingress DNS records

If you removed the DNS zone configuration when creating Kubernetes manifests and generating Ignition configs, you must manually create DNS records that point at the ingress load balancer. You can create either a wildcard *.apps.{baseDomain}. or specific records. You can use A, CNAME, and other records per your requirements.

Prerequisites

Configure a GCP account.
Remove the DNS Zone configuration when creating Kubernetes manifests and generating Ignition configs.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.
Create the worker machines.

Procedure

Wait for the Ingress router to create a load balancer and populate the EXTERNAL-IP field:

$ oc -n openshift-ingress get service router-default

Example output

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
router-default   LoadBalancer   172.30.18.154   35.233.157.184   80:32288/TCP,443:31215/TCP   98

Add the A record to your zones:

To use A records:

Export the variable for the router IP address:

$ export ROUTER_IP=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

Add the A record to the private zones:

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone

For an external cluster, also add the A record to the public zones:

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

To add explicit domains instead of using a wildcard, create entries for each of the cluster’s current routes:

$ oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

Completing a GCP installation on user-provisioned infrastructure

After you start the OpenShift Container Platform installation on Google Cloud Platform (GCP) user-provisioned infrastructure, you can monitor the cluster events until the cluster is ready.

Prerequisites

Deploy the bootstrap machine for an OpenShift Container Platform cluster on user-provisioned GCP infrastructure.
Install the oc CLI and log in.

Procedure

Complete the cluster installation:

$ ./openshift-install --dir <installation_directory> wait-for install-complete (1)

Example output

INFO Waiting up to 30m0s for the cluster to initialize...

1	For `<installation_directory>`, specify the path to the directory that you stored the installation files in.

The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
It is recommended that you use Ignition config files within 12 hours after they are generated because the 24-hour certificate rotates from 16 to 22 hours after the cluster is installed. By using the Ignition config files within 12 hours, you can avoid installation failure if the certificate update runs during installation.

Observe the running state of your cluster.

Run the following command to view the current cluster version and status:

$ oc get clusterversion

Example output

NAME      VERSION   AVAILABLE   PROGRESSING   SINCE   STATUS
version             False       True          24m     Working towards 4.5.4: 99% complete

Telemetry access for OpenShift Container Platform

In OpenShift Container Platform 4.10, the Telemetry service, which runs by default to provide metrics about cluster health and the success of updates, requires internet access. If your cluster is connected to the internet, Telemetry runs automatically, and your cluster is registered to OpenShift Cluster Manager.

After you confirm that your OpenShift Cluster Manager inventory is correct, either maintained automatically by Telemetry or manually by using OpenShift Cluster Manager, use subscription watch to track your OpenShift Container Platform subscriptions at the account or multi-cluster level.
