In OpenShift Container Platform version 4.11, you can install a customized
cluster on infrastructure that the installation program provisions on
Google Cloud Platform (GCP). To customize the installation, you modify
parameters in the install-config.yaml
file before you install the cluster.
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 configured a GCP project to host the cluster.
If you use a firewall, you configured it to allow the sites that your cluster requires access to.
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.
In OpenShift Container Platform 4.11, you require access to the internet to install your cluster.
You must have internet access to:
Access OpenShift Cluster Manager Hybrid Cloud Console 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. |
During an OpenShift Container Platform installation, you can provide an SSH public key to the installation program. The key is passed to the Red Hat Enterprise Linux CoreOS (RHCOS) nodes through their Ignition config files and is used to authenticate SSH access to the nodes. The key is added to the ~/.ssh/authorized_keys
list for the core
user on each node, which enables password-less authentication.
After the key is passed to the nodes, you can use the key pair to SSH in to the RHCOS nodes as the user core
. To access the nodes through SSH, the private key identity must be managed by SSH for your local user.
If you want to SSH in to your cluster nodes to perform installation debugging or disaster recovery, you must provide the SSH public key during the installation process. The ./openshift-install gather
command also requires the SSH public key to be in place on the cluster nodes.
Do not skip this procedure in production environments, where disaster recovery and debugging is required. |
You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs. |
If you do not have an existing SSH key pair on your local machine to use for authentication onto your cluster nodes, create one. For example, on a computer that uses a Linux operating system, run the following command:
$ ssh-keygen -t ed25519 -N '' -f <path>/<file_name> (1)
1 | Specify the path and file name, such as ~/.ssh/id_ed25519 , of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory. |
If you plan to install an OpenShift Container Platform cluster that uses FIPS validated or Modules In Process cryptographic libraries on the |
View the public SSH key:
$ cat <path>/<file_name>.pub
For example, run the following to view the ~/.ssh/id_ed25519.pub
public key:
$ cat ~/.ssh/id_ed25519.pub
Add the SSH private key identity to the SSH agent for your local user, if it has not already been added. SSH agent management of the key is required for password-less SSH authentication onto your cluster nodes, or if you want to use the ./openshift-install gather
command.
On some distributions, default SSH private key identities such as |
If the ssh-agent
process is not already running for your local user, start it as a background task:
$ eval "$(ssh-agent -s)"
Agent pid 31874
If your cluster is in FIPS mode, only use FIPS-compliant algorithms to generate the SSH key. The key must be either RSA or ECDSA. |
Add your SSH private key to the ssh-agent
:
$ ssh-add <path>/<file_name> (1)
1 | Specify the path and file name for your SSH private key, such as ~/.ssh/id_ed25519 |
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
Set the GOOGLE_APPLICATION_CREDENTIALS
environment variable to the full path to your service account private key file.
$ export GOOGLE_APPLICATION_CREDENTIALS="<your_service_account_file>"
Verify that the credentials were applied.
$ gcloud auth list
When you install OpenShift Container Platform, provide the SSH public key to the installation program.
Before you install OpenShift Container Platform, download the installation file on a local computer.
You have a computer that runs Linux or macOS, with 500 MB of local disk space.
Access the Infrastructure Provider page on the OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Select your infrastructure provider.
Navigate to the page for your installation type, download the installation program that corresponds with your host operating system and architecture, and place the file in the directory where you will store the installation configuration files.
The installation program creates several files on the computer that you use to install your cluster. You must keep the installation program and the files that the installation program creates after you finish installing the cluster. Both files are required to delete the cluster. |
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. To remove your cluster, complete the OpenShift Container Platform uninstallation procedures for your specific cloud provider. |
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
$ tar -xvf openshift-install-linux.tar.gz
Download your installation pull secret from the Red Hat OpenShift Cluster Manager. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.
You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.
Obtain service principal permissions at the subscription level.
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. |
When specifying the directory:
Verify that the directory has the execute
permission. This permission is required to run Terraform binaries under the installation directory.
Use an empty directory. Some installation assets, such as bootstrap X.509 certificates, have short expiration intervals, therefore 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:
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 |

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

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
.
As part of the installation process, you specify the custom machine type in the install-config.yaml
file.

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

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. |

Using the GCP Marketplace offering lets you deploy an OpenShift Container Platform cluster, which is billed on pay-per-use basis (hourly, per core) through GCP, while still being supported directly by Red Hat.
By default, the installation program downloads and installs the Red Hat Enterprise Linux CoreOS (RHCOS) image that is used to deploy compute machines. To deploy an OpenShift Container Platform cluster using an RHCOS image from the GCP Marketplace, override the default behavior by modifying the install-config.yaml

In OpenShift Container Platform 4.11, 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 Hybrid Cloud Console.
After you confirm that your OpenShift Cluster Manager Hybrid Cloud Console 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.
See About remote health monitoring for more information about the Telemetry service
If necessary, you can opt out of remote health reporting.
