Chapter 1. What is Red Hat OpenShift Cluster Manager?

You can use Red Hat OpenShift Cluster Manager to work with your Red Hat OpenShift cloud services and Red Hat OpenShift Container Platform clusters. With OpenShift Cluster Manager you can create, subscribe, and manage different types of OpenShift clusters from a single user interface.

Red Hat OpenShift Container Platform is a self-managed hybrid cloud platform that you can deploy on-premises, on bare metal, or on public cloud infrastructure.

OpenShift Dedicated is a fully managed service running on AWS or Google Cloud Platform (GCP), where Red Hat handles the cluster operations on your behalf.

Regardless of your deployment model, you can use OpenShift Cluster Manager to create and manage both your OpenShift Container Platform and OpenShift Dedicated clusters from a single, unified dashboard.

You can use the OpenShift Cluster Manager user interface to create OpenShift Container Platform clusters and subscribe the clusters to Red Hat for support. OpenShift Cluster Manager provides the installer and instructions to create self-managed clusters on each supported environment for OpenShift Container Platform. You can then view and manage your OpenShift Container Platform clusters in OpenShift Cluster Manager, or log in to the OpenShift Container Platform web console to access and configure your clusters.

You can find information about the latest OpenShift Container Platform release versions available, as well as update channels for your clusters from the Releases menu in OpenShift Cluster Manager. For insights about your clusters, use the integrated services within the Red Hat Hybrid Cloud Console such as Red Hat Lightspeed Advisor, Subscriptions, and Cost Management.

You can use the OpenShift Cluster Manager user interface to create, view, and manage your OpenShift Dedicated clusters.

OpenShift Dedicated clusters are managed by Red Hat and are known as managed clusters. You can create OpenShift Dedicated clusters on AWS or Google Cloud Platform, using either the Red Hat managed cloud account or your own cloud provider account. When you use your own cloud provider account, this billing model is referred to as Customer Cloud Subscription (CCS) in OpenShift Cluster Manager.

You can use the OpenShift Cluster Manager user interface to create, view and manage your Red Hat OpenShift Service on AWS (ROSA) clusters. ROSA is a fully-managed OpenShift service, jointly managed and supported by Red Hat and Amazon Web Services (AWS). This service is procured directly from your AWS aROSAnt. ROSA pricing is consumption based and is billed directly to your AWS account.

You can quickly deploy ROSA from OpenShift Cluster Manager or using the ROSA CLI. In OpenShift Cluster Manager, you can manage your ROSA cluster and any add-on services.

OpenShift Cluster Manager is integrated with the following services hosted on the Red Hat Hybrid Cloud Console, which you can use to gain deeper understanding and manage your OpenShift Container Platform clusters.

You need a Red Hat account to access OpenShift Cluster Manager and the Red Hat Hybrid Cloud Console. You can then deploy an OpenShift Container Platform cluster in OpenShift Cluster Manager.

For greater security, you can use two-factor authentication (2FA) to access OpenShift Cluster Manager and the Red Hat Hybrid Cloud Console. You must enable 2FA in your Red Hat account to use 2FA to access OpenShift Cluster Manager. Organization Administrators can enable 2FA for all users in their organization, or individual users can configure 2FA for their own Red Hat account.

To enable 2FA in your Red Hat account or learn more, see the Using Two-Factor Authentication guide.

Add-ons are additional services that you can install to your existing Red Hat OpenShift Dedicated and Red Hat OpenShift Service on AWS (ROSA) clusters to enhance cluster capabilities.

You can install and manage add-on services from a cluster’s Add-ons tab in OpenShift Cluster Manager.

Depending on the add-on service, you might need additional Red Hat subscriptions or quota to use it. See the documentation for the add-on to learn more about the requirements and for instructions for using the add-on.

Configure notification settings to monitor OpenShift cluster events effectively. You can manage default email notifications and integrate third-party services, such as Slack, Google Chat, and Microsoft Teams, for cluster event alerts. By default, you will receive email notifications about OpenShift cluster events.

In addition to email notifications, Red Hat Hybrid Cloud Console Organization Administrators, Cloud Administrators, or users with Notifications Administrator permissions can configure cluster event notifications through third-party products such as Slack, Google Chat, and Microsoft Teams.
