Before you begin

This task assumes that the following prerequisites are met:

Prerequisite Where to find more information
The cluster meets the minimum requirements for installing Runtime 22.1 on R 3.6. If this task is not complete, see System requirements.
The workstation from which you will run the installation is set up as a client workstation and includes the following command-line interfaces:
  • Cloud Pak for Data CLI: cpd-cli
  • OpenShift® CLI: oc
 If this task is not complete, see Setting up a client workstation.
The Cloud Pak for Data control plane is installed. If this task is not complete, see Installing the platform and services.
For environments that use a private container registry, such as air-gapped environments, the Runtime 22.1 on R 3.6 software images are mirrored to the private container registry. If this task is not complete, see Mirroring images to a private container registry.

  1. Logging in to the cluster
  2. Installing the service
  3. Validating the installation
  4. What to do next

Logging in to the cluster

To run cpd-cli manage commands, you must log in to the cluster.

To log in to the cluster:

  1. Run the cpd-cli manage login-to-ocp command to log in to the cluster as a user with sufficient permissions to complete this task. For example:
    cpd-cli manage login-to-ocp \
--username=${OCP_USERNAME} \
--password=${OCP_PASSWORD} \
--server=${OCP_URL}

--release=${VERSION} \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--extra-vars="cr_name=ibm-cpd-ws-runtime-r36" \
--license_acceptance=true
