Prerequisites for converting a connected cluster to a disconnected cluster

You must meet several prerequisites before converting a connected cluster to a disconnected cluster.

The following prerequisites must be met:

  • The oc client is installed.

  • A running cluster.

  • An installed mirror registry, which is a container image registry that supports Docker v2-2 in the location that will host the Red Hat OpenShift Container Platform cluster, such as one of the following registries:

    • Red Hat Quay

    • JFrog Artifactory

    • Sonatype Nexus Repository

    • Harbor

    If you have a subscription to Red Hat Quay, see the documentation on "Deploying Red Hat Quay for proof-of-concept purposes" or "Deploying Red Hat Quay by using the Quay Operator".

  • The mirror repository must be configured to share images. For example, a Red Hat Quay repository requires organizations to share images. For more information, see the "Red Hat Quay documentation on organizations".

  • Access to the internet to obtain the necessary container images.
