Import

A typical organization needs to address four critical capabilities (automation, visibility, security and governance) for their Kubernetes clusters. The platform addresses these requirements for Red Hat Openshift clusters.

Prerequisites

• You have access to an Org with Org Admin or Infra Admin privileges.
• You have already installed and deployed a Red Hat Openshift cluster in a supported environment and configured and have kubectl access to the cluster.
• Ensure that your cluster is healthy and has sufficient resources available to accommodate additional resources.

Important

You can also automate the entire process using the RCTL CLI or Swagger based APIs or a Terraform Provider.

Create Cluster

• Navigate to the project in your Org where you would like to import the Openshift cluster.
• Click on New Cluster and select the option to "Import Existing Kubernetes Cluster"

Select Type

• Select "Datacenter/Edge" for operating environment and "RedHat Openshift" for Kubernetes distribution.

Configure Details

This step mostly contains "optional" configurations that are sometimes required for specialized environments or requirements.

• Optionally, specify location (if you plan to use location based policies).
• Select a custom blueprint and version if you created one.
• Optionally, specify proxy configuration if your environment requires a forward proxy for the Kubernetes management operator to connect to the controller.

Install Operator

• Download the bootstrap YAML file.
• Apply the bootstrap file on your Openshift cluster using kubectl.

This step will deploy the Kubernetes mgmt operator on your Openshift cluster, start downloading the required container images and establish connectivity with the controller. This step can take 2-3 minutes and depends on the resources available on the cluster and network download speeds to download the required container images.

Verify Import

After the previous step is complete, you can verify if the resources are operational by using the "zero trust kubectl" channel from the web console. Click on "Kubectl" on the web console and type the following command.

kubectl get ns

You should see something like the following on your Openshift cluster.
