Introduction to Red Hat OpenShift Service on AWS (ROSA)
Connect a managed cluster to Red Hat cloud services and enumerate the benefits.
By registering your OpenShift clusters with the Red Hat cloud, you enable additional services and features.
With most deployment scenarios, the cluster creation process performs that registration for you. For example, the ROSA cluster creation process automatically registers your clusters.
The registration process requires a pull secret, which is a secret token associated with your Red Hat account. Each Red Hat account has a pull secret that Red Hat automatically creates when you create your account. For registering your OpenShift cluster, you retrieve the pull secret from your Red Hat account and then store it in an OpenShift secret in your cluster. The ROSA cluster creation process performs that operation for you: it retrieves your pull secret and creates the OpenShift secret.
Inside your OpenShift cluster, some operators and processes use the pull secret from the OpenShift secret to authenticate with Red Hat services. For example, OpenShift uses the pull secret for the following purposes:
Retrieve container images from the
Quay.ioandregistry.redhat.iosecured registries. These registries provide images for the OpenShift components.Upload information about the cluster health and configuration to the Red Hat OpenShift Cluster Manager. The platform processes that information and provides recommendations that you can consult from the OpenShift Cluster Manager web interface. The Red Hat support team also uses the collected information to help diagnose cluster issues when you open a support case.
Access and install OpenShift operators from the Operator Hub.
Registering your OpenShift clusters enables you to manage and monitor them from the OpenShift Cluster Manager web interface at https://console.redhat.com/openshift.
From the OpenShift Cluster Manager web interface, navigate to to lists the cluster in your organization.
Click to limit the view to the clusters you deployed by using your Red Hat account.
By selecting a cluster from that list, you can review its status and obtain general information from the tab.
By using the other tabs, you can manage several aspects of your cluster, such as configuring identity providers or updating the OpenShift version.
Registered OpenShift clusters regularly send status, configuration, and performance data to Red Hat Insights. Red Hat Insights is a service hosted by Red Hat that analyzes the data it receives from your clusters and publishes the result to the OpenShift Cluster Manager.
Red Hat Insights recommends actions to improve security, performance, or service availability. To access these recommendations from the OpenShift Cluster Manager web interface, navigate to → and then select your cluster. Each recommendation comes with details and instructions on how to resolve the issue.
Red Hat Insights also lists the known Common Vulnerabilities and Exposures (CVEs) affecting your clusters. To list these CVEs from the OpenShift Cluster Manager web interface, navigate to → and then select your cluster. Each entry describes a CVE and provides links for more information.
Red Hat Marketplace provides certified software from Red Hat and its partners. You can try, buy, and immediately deploy these products on any OpenShift installation.
Note
Red Hat Marketplace might not be available in your country.
You can access the Red Hat Marketplace at https://marketplace.redhat.com/. You need to create a user account and then register your OpenShift clusters with Red Hat Marketplace to consume products from the platform.
The pull secret that connects your ROSA clusters to the OpenShift Cluster Manager also allows accessing Red Hat container registries to pull container images from image streams, source-to-image builders, and add-on operators.
The reference section provides more information about image streams and source-to-image.
