Accessing Classic clusters through the private cloud service endpoint

For Red Hat OpenShift Classic clusters that have only the private cloud service endpoint enabled, you must be connected to the IBM Cloud classic private network through a VPN connection to access the cluster.

Before you begin

  1. Install the required CLI tools.
  2. Set up a Virtual Private Network (VPN) for VPC connection to the IBM Cloud classic private network.
  3. Verify your cluster is healthy: ibmcloud oc cluster get -c CLUSTER_NAME_OR_ID.

  3. Log in to the cluster.

    • As admin: ibmcloud oc cluster config -c CLUSTER_NAME_OR_ID --admin --endpoint private
    • With a passcode: oc login -u passcode -p <iam_passcode> --server=<private_master_URL>
