Before you create a Red Hat OpenShift Service on AWS (ROSA) cluster, you must complete the AWS prerequisites, verify that the required AWS service quotas are available, and set up your environment.

This document provides an overview of the ROSA workflow stages and refers to detailed resources for each stage.

AWS Security Token Service (STS) is the recommended credential mode for installing and interacting with clusters on Red Hat OpenShift Service on AWS (ROSA) because it provides enhanced security.

Overview of the ROSA deployment workflow

You can follow the workflow stages outlined in this section to set up and access a Red Hat OpenShift Service on AWS (ROSA) cluster.

  1. Perform the AWS prerequisites. To deploy a ROSA cluster, your AWS account must meet the prerequisite requirements.

  2. Review the required AWS service quotas. To prepare for your cluster deployment, review the AWS service quotas that are required to run a ROSA cluster.

  3. Configure your AWS account. Before you create a ROSA cluster, you must enable ROSA in your AWS account, install and configure the AWS CLI (aws) tool, and verify the AWS CLI tool configuration.

  4. Install the ROSA and OpenShift CLI tools and verify the AWS servce quotas. Install and configure the ROSA CLI (rosa) and the OpenShift CLI (oc). You can verify if the required AWS resource quotas are available by using the ROSA CLI.

  5. Create a ROSA cluster or Create a ROSA cluster using AWS PrivateLink. Use the ROSA CLI (rosa) to create a cluster. You can optionally create a ROSA cluster with AWS PrivateLink.

  6. Access a cluster. You can configure an identity provider and grant cluster administrator privileges to the identity provider users as required. You can also access a newly deployed cluster quickly by configuring a cluster-admin user.

  7. Revoke access to a ROSA cluster for a user. You can revoke access to a ROSA cluster from a user by using the ROSA CLI or the web console.

  8. Delete a ROSA cluster. You can delete a ROSA cluster by using the ROSA CLI (rosa).
