Introduction

Most developers are using OpenShift since it helps them provide a platform that allows them to build once and deploy anywhere. AWS Identified these benefits of OpenShift and integrated its services with Red Hat. So that it helps developers like you and me accelerate our application development process by leveraging familiar OpenShift APIs and tools for deployments on AWS. With all these added advantages of ROSA, it becomes too important for any developer to get to know it in detail. This article will break down the ins and outs of Red hat OpenShift Service on AWS.

Red Hat OpenShift Service on AWS

Red Hat OpenShift Service on AWS(ROSA) is a Managed Service. ROSA is made available through the AWS Management Console. ROSA helps users build, scale, and manage containerised applications on AWS. With ROSA, we can create Kubernetes clusters using Red Hat OpenShift APIs and tooling and could have access to the AWS service's entire breadth and depth.ROSA offers tight integration with other AWS Services. It streamlines moving on-premises Red Hat OpenShift workloads to AWS. With ROSA, we can access Red Hat OpenShift licensing, billing, and support all directly through AWS.

AWS doesn't charge any up-front costs to use ROSA. We pay only for the container clusters and nodes that we use. It goes with pay-as-you-go pricing. As a User, You don't have to worry about complex, multi-year contracts. This flexibility means we can align our Red Hat OpenShift consumption in AWS based on our business needs.

ROSA works in the following steps

  • Permissions Configuration
  • Download CLI
  • Provision Cluster
  • Deploy our applications

ROSA clusters come with a fully-managed control plane and compute nodes. Red Hat site reliability engineers (SRE) are responsible for Installation, management, maintenance, and upgrades ). ROSA clusters are deployed in user accounts with support for existing VPCs.

Get Started with ROSA 

Let's get started with Red Hat OpenShift Service(ROSA) on AWS.

Prerequisites

Before we set up ROSA, we need to make sure we have completed all the below-mentioned actions:

  • Latest AWS CLI needed to be installed and configured.
  • The latest ROSA CLI needed to be installed and configured.
  • Follow all the steps in the Getting Start workflow guide in the Red Hat documentation. 
  • We need to ensure that we meet all of the requirements mentioned in the Customer Requirements topic in the Red Hat documentation. 

Enable Red Hat OpenShift Service on AWS

Red Hat OpenShift Service on AWS needs to be enabled. Go to the AWS Management Console to enable these services.

  1. Navigate yourself to the Red Hat OpenShift Service on AWS.
  2. Select Enable OpenShift.

Using ROSA CLI to Create Cluster

After completing all steps mentioned above, we can use ROSA CLI to create and manage our cluster through Red Hat OpenShift. If you want to look for more information, go to  Creating a ROSA cluster.

Troubleshooting - ROSA

This section will cover troubleshooting some of the requirements necessary to create a cluster, including account permissions, ROSA service enablement, and service quotas.

Troubleshooting Permissions

We receive Red Hat and AWS support through AWS with Red Hat OpenShift Service on AWS (ROSA). If we want to receive support from Red Hat site reliability engineers (SRE), we must fulfil several requirements. To get more information about these requirements, look into the Minimum required service control policy page in the Red Hat OpenShift.To verify whether our AWS account has the correct permissions or not, run the following command.

rosa verify permissions


If you receive any errors, check if it's because a service control policy (SCP) is not applied to your AWS account. If using SCP is required, then look at the Red Hat Requirements for Customer Cloud Subscriptions page for more information.

Troubleshooting ROSA enablement

Red Hat OpenShift Service on AWS uses AWS Marketplace for facilitating subscription management, billing, and metering. The Red Hat console directly subscribes to AWS Marketplace when the user enables these services. The user IAM principal requires permission for an AWS-marketplace subscription to enable these services. AWS provides a managed IAM policy that includes the minimum permissions necessary to enable ROSA in the AWS Management Console and manage the ROSA AWS Marketplace subscription.

Frequently Asked Questions

Red Hat OpenShift is a Kubernetes distribution whose primary focus is on developer experience and application security. Red Hat OpenShift helps developers develop and deploy applications to more than one host. 

Explain briefly Red Hat OpenShift Service on AWS?

Red Hat OpenShift Service (ROSA) on AWS is a Managed Service. ROSA helps users build, scale, and manage containerized applications on AWS. ROSA is made available through the AWS Management Console.

How do we enable Red Hat OpenShift Service on AWS?

To enable Red Hat OpenShift Service on AWS, we need to go to the AWS Management Console to enable it.

  1. Navigate yourself to the Red Hat OpenShift Service on AWS.
  2. Select Enable OpenShift.

How to verify whether our AWS account has correct permissions or not?

To verify whether our AWS account has the correct permissions or not, run the following command.

rosa verify permissions


If you receive any errors, check if it's because a service control policy(SCP) is not applied to your AWS account.
