You can create a ROSA cluster either with or without the AWS Security Token Service (STS). The procedures in this document enable you to create a cluster that uses AWS STS. For more information about using AWS STS with ROSA clusters, see Using the AWS Security Token Service.

Prerequisites

You reviewed the introduction to Red Hat OpenShift Service on AWS (ROSA), and the documentation on ROSA architecture models and architecture concepts.
You have read the documentation on limits and scalability and the guidelines for planning your environment.
You have reviewed the detailed AWS prerequisites for ROSA with STS.
You have the AWS service quotas that are required to run a ROSA cluster.

Setting up the environment

Before you create a Red Hat OpenShift Service on AWS (ROSA) cluster, you must set up your environment by completing the following tasks:

Verify ROSA prerequisites against your AWS and Red Hat accounts.
Install and configure the required command line interface (CLI) tools.
Verify the configuration of the CLI tools.

You can follow the procedures in this section to complete these setup requirements.

Verifying ROSA prerequisites

Use the steps in this procedure to enable Red Hat OpenShift Service on AWS (ROSA) in your AWS account.

Prerequisites

You have a Red Hat account.
You have an AWS account.

Consider using a dedicated AWS account to run production clusters. If you are using AWS Organizations, you can use an AWS account within your organization or create a new one.

Procedure

Sign in to the AWS Management Console.
Navigate to the ROSA service.
Click Get started.

Installing and configuring the required CLI tools

Use the following steps to install and configure AWS, Red Hat OpenShift Service on AWS (ROSA), and OpenShift CLI tools on your workstation.

Prerequisites

You have an AWS account.
You created a Red Hat account.

You can create a Red Hat account by navigating to console.redhat.com and selecting Register for a Red Hat account.

Procedure

Install and configure the latest AWS CLI (aws).
1. Follow the AWS Command Line Interface documentation to install and configure the AWS CLI for your operating system.
  
  Specify your aws_access_key_id, aws_secret_access_key, and region in the .aws/credentials file. See AWS Configuration basics in the AWS documentation.
  
  You can alternatively use the AWS_DEFAULT_REGION environment variable to set the default AWS region.
2. Query the AWS API to verify if the AWS CLI is installed and configured correctly:
  $ aws sts get-caller-identity
  Example output
  <aws_account_id> arn:aws:iam::<aws_account_id>:user/<username> <aws_user_id>
Install and configure the latest ROSA CLI (rosa).
1. Download the latest version of the rosa CLI for your operating system from the Downloads page on the Red Hat OpenShift Cluster Manager Hybrid Cloud Console.
2. Extract the rosa binary file from the downloaded archive. The following example extracts the binary from a Linux tar archive:
  $ tar xvf rosa-linux.tar.gz
3. Add rosa to your path. In the following example, the /usr/local/bin directory is included in the path of the user:
  $ sudo mv rosa /usr/local/bin/rosa
4. Verify if the rosa CLI tool is installed correctly by querying the rosa version:
  $ rosa version
  Example output
  1.2.15 Your ROSA CLI is up to date.
5. Optional: Enable tab completion for the rosa CLI. With tab completion enabled, you can press the Tab key twice to automatically complete subcommands and receive command suggestions.
  
  rosa tab completion is available for different shell types. The following example enables persistent tab completion for Bash on a Linux host. The command generates a rosa tab completion configuration file for Bash and saves it to the /etc/bash_completion.d/ directory:
  # rosa completion bash > /etc/bash_completion.d/rosa
  You must open a new terminal to activate the configuration.
  
  For steps to configure rosa tab completion for different shell types, see the help menu by running rosa completion --help.
6. Log in to your Red Hat account by using the rosa CLI:
  $ rosa login
  Example output
  To login to your Red Hat account, get an offline access token at https://console.redhat.com/openshift/token/rosa ? Copy the token and paste it here:
  Go to the URL listed in the command output to obtain an offline access token. Specify the token at the CLI prompt to log in.
  
  You can subsequently specify the offline access token by using the --token="<offline_access_token>" argument when you run the rosa login command.
7. Verify if you are logged in successfully and check your credentials:
  $ rosa whoami
  Example output
  AWS Account ID: <aws_account_number> AWS Default Region: us-east-1 AWS ARN: arn:aws:iam::<aws_account_number>:user/<aws_user_name> OCM API: https://api.openshift.com OCM Account ID: <red_hat_account_id> OCM Account Name: Your Name OCM Account Username: you@domain.com OCM Account Email: you@domain.com OCM Organization ID: <org_id> OCM Organization Name: Your organization OCM Organization External ID: <external_org_id>
  Check that the information in the output is correct before proceeding.
Install and configure the latest OpenShift CLI (oc).
1. Use the rosa CLI to download the latest version of the oc CLI:
  $ rosa download openshift-client
2. Extract the oc binary file from the downloaded archive. The following example extracts the files from a Linux tar archive:
  $ tar xvf openshift-client-linux.tar.gz
3. Add the oc binary to your path. In the following example, the /usr/local/bin directory is included in the path of the user:
  $ sudo mv oc /usr/local/bin/oc
4. Verify if the oc CLI is installed correctly:
  $ rosa verify openshift-client
  Example output
  I: Verifying whether OpenShift command-line tool is available... I: Current OpenShift Client Version: 4.9.12

Creating a ROSA cluster with STS

Choose from one of the following methods to deploy a Red Hat OpenShift Service on AWS (ROSA) cluster that uses the AWS Security Token Service (STS). In each scenario, you can deploy your cluster by using Red Hat OpenShift Cluster Manager or the ROSA CLI (rosa):

Creating a ROSA cluster with STS using the default options: You can create a ROSA cluster with STS quickly by using the default options and automatic STS resource creation.
Creating a ROSA cluster with STS using customizations: You can create a ROSA cluster with STS using customizations. You can also choose between the auto and manual modes when creating the required STS resources.

Creating a cluster administrator user for quick cluster access

Before configuring an identity provider, you can create a user with cluster-admin privileges for immediate access to your Red Hat OpenShift Service on AWS (ROSA) cluster.

The cluster administrator user is useful when you need quick access to a newly deployed cluster. However, consider configuring an identity provider and granting cluster administrator privileges to the identity provider users as required. For more information about setting up an identity provider for your ROSA cluster, see Configuring an identity provider and granting cluster access.

Prerequisites

You have an AWS account.
You installed and configured the latest AWS (aws), ROSA (rosa), and OpenShift (oc) CLIs on your workstation.
You logged in to your Red Hat account by using the rosa CLI.
You created a ROSA cluster.

Procedure

Create a cluster administrator user:

$ rosa create admin --cluster=<cluster_name> (1)

1	Replace `<cluster_name>` with the name of your cluster.

Example output

W: It is recommended to add an identity provider to login to this cluster. See 'rosa create idp --help' for more information.
I: Admin account has been added to cluster '<cluster_name>'.
I: Please securely store this generated password. If you lose this password you can delete and recreate the cluster admin user.
I: To login, run the following command:

   oc login https://api.example-cluster.wxyz.p1.openshiftapps.com:6443 --username cluster-admin --password d7Rca-Ba4jy-YeXhs-WU42J

I: It may take up to a minute for the account to become active.

It might take approximately one minute for the cluster-admin user to become active.

Log in to the cluster through the CLI:
1. Run the command provided in the output of the preceding step to log in:
  $ oc login <api_url> --username cluster-admin --password <cluster_admin_password> (1)
  1 Replace <api_url> and <cluster_admin_password> with the API URL and cluster administrator password for your environment.
2. Verify if you are logged in to the ROSA cluster as the cluster-admin user:
  $ oc whoami
  Example output
  cluster-admin

Configuring an identity provider and granting cluster access

Red Hat OpenShift Service on AWS (ROSA) includes a built-in OAuth server. After your ROSA cluster is created, you must configure OAuth to use an identity provider. You can then add members to your configured identity provider to grant them access to your cluster.

You can also grant the identity provider users with cluster-admin or dedicated-admin privileges as required.

Configuring an identity provider

You can configure different identity provider types for your Red Hat OpenShift Service on AWS (ROSA) cluster. Supported types include GitHub, GitHub Enterprise, GitLab, Google, LDAP, OpenID Connect and htpasswd identity providers.

The htpasswd identity provider option is included only to enable the creation of a single, static administration user. htpasswd is not supported as a general-use identity provider for Red Hat OpenShift Service on AWS.

The following procedure configures a GitHub identity provider as an example.

Prerequisites

You have an AWS account.
You installed and configured the latest AWS (aws), ROSA (rosa), and OpenShift (oc) CLIs on your workstation.
You logged in to your Red Hat account by using the rosa CLI.
You created a ROSA cluster.
You have a GitHub user account.

Procedure

Go to github.com and log in to your GitHub account.
If you do not have an existing GitHub organization to use for identity provisioning for your ROSA cluster, create one. Follow the steps in the GitHub documentation.

Configure a GitHub identity provider for your cluster that is restricted to the members of your GitHub organization.

Configure an identity provider using the interactive mode:

$ rosa create idp --cluster=<cluster_name> --interactive (1)

1	Replace `<cluster_name>` with the name of your cluster.

Example output

I: Interactive mode enabled.
Any optional fields can be left empty and a default will be selected.
? Type of identity provider: github
? Identity provider name: github-1
? Restrict to members of: organizations
? GitHub organizations: <github_org_name> (1)
? To use GitHub as an identity provider, you must first register the application:
  - Open the following URL:
    https://github.com/organizations/<github_org_name>/settings/applications/new?oauth_application%5Bcallback_url%5D=https%3A%2F%2Foauth-openshift.apps.<cluster_name>/<random_string>.p1.openshiftapps.com%2Foauth2callback%2Fgithub-1&oauth_application%5Bname%5D=<cluster_name>&oauth_application%5Burl%5D=https%3A%2F%2Fconsole-openshift-console.apps.<cluster_name>/<random_string>.p1.openshiftapps.com
  - Click on 'Register application'
...

1	Replace `<github_org_name>` with the name of your GitHub organization.

Follow the URL in the output and select Register application to register a new OAuth application in your GitHub organization. By registering the application, you enable the OAuth server that is built into ROSA to authenticate members of your GitHub organization into your cluster.

The fields in the Register a new OAuth application GitHub form are automatically filled with the required values through the URL defined by the rosa CLI tool.

Use the information from your GitHub OAuth application page to populate the remaining rosa create idp interactive prompts.

Continued example output

...
? Client ID: <github_client_id> (1)
? Client Secret: [? for help] <github_client_secret> (2)
? GitHub Enterprise Hostname (optional):
? Mapping method: claim (3)
I: Configuring IDP for cluster '<cluster_name>'
I: Identity Provider 'github-1' has been created.
   It will take up to 1 minute for this configuration to be enabled.
   To add cluster administrators, see 'rosa grant user --help'.
   To login into the console, open https://console-openshift-console.apps.<cluster_name>.<random_string>.p1.openshiftapps.com and click on github-1.

1	Replace `<github_client_id>` with the client ID for your GitHub OAuth application.
2	Replace `<github_client_secret>` with a client secret for your GitHub OAuth application.
3	Specify `claim` as the mapping method.

It might take approximately two minutes for the identity provider configuration to become active. If you have configured a cluster-admin user, you can watch the OAuth pods redeploy with the updated configuration by running oc get pods -n openshift-authentication --watch.

Enter the following command to verify that the identity provider has been configured correctly:

$ rosa list idps --cluster=<cluster_name>

Example output

NAME        TYPE      AUTH URL
github-1    GitHub    https://oauth-openshift.apps.<cluster_name>.<random_string>.p1.openshiftapps.com/oauth2callback/github-1

Deleting a ROSA cluster and the AWS STS resources

You can delete a ROSA cluster that uses the AWS Security Token Service (STS) by using the ROSA CLI (rosa). You can also use the ROSA CLI to delete the AWS Identity and Access Management (IAM) account-wide roles, the cluster-specific Operator roles, and the OpenID Connect (OIDC) provider. To delete the account-wide inline and Operator policies, you can use the AWS IAM Console.

Account-wide IAM roles and policies might be used by other ROSA clusters in the same AWS account. You must only remove the resources if they are not required by other clusters.

Prerequisites

You installed and configured the latest AWS (aws), ROSA (rosa), and OpenShift (oc) CLIs on your workstation.
You logged in to your Red Hat account by using the rosa CLI.
You created a ROSA cluster.

Procedure

Delete a cluster and watch the logs, replacing <cluster_name> with the name or ID of your cluster:

$ rosa delete cluster --cluster=<cluster_name> --watch

You must wait for the cluster deletion to complete before you remove the IAM roles, policies, and OIDC provider. The account-wide roles are required to delete the resources created by the installer. The cluster-specific Operator roles are required to clean-up the resources created by the OpenShift Operators. The Operators use the OIDC provider to authenticate.

Delete the OIDC provider that the cluster Operators use to authenticate:
```
$ rosa delete oidc-provider -c <cluster_id> --mode auto (1)
```
1 Replace <cluster_id> with the ID of the cluster.

You can use the -y option to automatically answer yes to the prompts.
Delete the cluster-specific Operator IAM roles:
```
$ rosa delete operator-roles -c <cluster_id> --mode auto (1)
```
1 Replace <cluster_id> with the ID of the cluster.

Delete the account-wide roles:

Account-wide IAM roles and policies might be used by other ROSA clusters in the same AWS account. You must only remove the resources if they are not required by other clusters.

$ rosa delete account-roles --prefix <prefix> --mode auto (1)

1	You must include the `--<prefix>` argument. Replace `<prefix>` with the prefix of the account-wide roles to delete. If you did not specify a custom prefix when you created the account-wide roles, specify the default prefix, `ManagedOpenShift`.

Delete the account-wide inline and Operator IAM policies that you created for ROSA deployments that use STS:
1. Log in to the AWS IAM Console.
2. Navigate to Access management → Policies and select the checkbox for one of the account-wide policies.
3. With the policy selected, click on Actions → Delete to open the delete policy dialog.
4. Enter the policy name to confirm the deletion and select Delete to delete the policy.
5. Repeat this step to delete each of the account-wide inline and Operator policies for the cluster.
