Prerequisites

  1. A Provisioned ROSA cluster

    This lab assumes you have access to a successfully provisioned a ROSA cluster. If you have not yet created a ROSA cluster, see ROSA quick start guide for more information.

  2. The OpenShift Command Line Interface (CLI)

    For more information, see Getting started with the OpenShift CLI.

  3. A GitHub Account

    Use your existing GitHub account or register at https://github.com/signup.

Understanding AWS account association

Before you can use Red Hat OpenShift Cluster Manager on the Red Hat Hybrid Cloud Console to create Red Hat OpenShift service on AWS (ROSA) clusters that use the AWS Security Token service (STS), you must associate your AWS account with your Red Hat organization. You can associate your account by creating and linking the following IAM roles.

OpenShift Cluster Manager role

Create an OpenShift Cluster Manager IAM role and link it to your Red Hat organization.

You can apply basic or administrative permissions to the OpenShift Cluster Manager role. The basic permissions enable cluster maintenance using OpenShift Cluster Manager. The administrative permissions enable automatic deployment of the cluster-specific Operator roles and the OpenID Connect (OIDC) provider using OpenShift Cluster Manager.

User role

Create a user IAM role and link it to your Red Hat user account. The Red Hat user account must exist in the Red Hat organization that is linked to your OpenShift Cluster Manager role.

The user role is used by Red Hat to verify your AWS identity when you use the OpenShift Cluster Manager Hybrid Cloud Console to install a cluster and the required STS resources.

Associating your AWS account with your Red Hat organization

Before using Red Hat OpenShift Cluster Manager on the Red Hat Hybrid Cloud Console to create Red Hat OpenShift service on AWS (ROSA) clusters that use the AWS Security Token service (STS), create an OpenShift Cluster Manager IAM role and link it to your Red Hat organization. Then, create a user IAM role and link it to your Red Hat user account in the same Red Hat organization.

Procedure

  1. Create an OpenShift Cluster Manager role and link it to your Red Hat organization:

    To enable automatic deployment of the cluster-specific Operator roles and the OpenID Connect (OIDC) provider using the OpenShift Cluster Manager Hybrid Cloud Console, you must apply the administrative privileges to the role by choosing the Admin OCM role command in the Accounts and roles step of creating a ROSA cluster. For more information about the basic and administrative privileges for the OpenShift Cluster Manager role, see Understanding AWS account association.

    If you choose the Basic OCM role command in the Accounts and roles step of creating a ROSA cluster in the OpenShift Cluster Manager Hybrid Cloud Console, you must deploy a ROSA cluster using manual mode. You will be prompted to configure the cluster-specific Operator roles and the OpenID Connect (OIDC) provider in a later step.

    		 
    $ rosa create ocm-role

    Select the default values at the prompts to quickly create and link the role.

  2. Create a user role and link it to your Red Hat user account:

    $ rosa create user-role

    Select the default values at the prompts to quickly create and link the role.

    The Red Hat user account must exist in the Red Hat organization that is linked to your OpenShift Cluster Manager role.
