Upgrading Watson Studio Runtimes from Version 4.8 to Version 5.0

An instance administrator can upgrade Watson Studio Runtimes from Cloud Pak for Data Version 4.8 to Version 5.0.

Who needs to complete this task?

Instance administrator To upgrade Watson Studio Runtimes, you must be an instance administrator. An instance administrator has permission to manage software in the following projects:

The operators project for the instance

The operators for this instance of Cloud Pak for Data are installed in the operators project. In the upgrade commands, the ${PROJECT_CPD_INST_OPERATORS} environment variable refers to the operators project.

The operands project for the instance

The Cloud Pak for Data control plane and the services for this instance of Cloud Pak for Data are installed in the operands project. In the upgrade commands, the ${PROJECT_CPD_INST_OPERANDS} environment variable refers to the operands project.

When do you need to complete this task?

Review the following options to determine whether you need to complete this task:

  • If you want to upgrade the Cloud Pak for Data control plane and one or more services at the same time, follow the process in Upgrading an instance of Cloud Pak for Data instead.
  • If you didn't upgrade Watson Studio Runtimes when you upgraded the Cloud Pak for Data control plane, complete this task to upgrade Watson Studio Runtimes.

    Repeat as needed If you are responsible for multiple instances of Cloud Pak for Data, you can repeat this task to upgrade more instances of Watson Studio Runtimes on the cluster.

Information you need to complete this task

Review the following information before you upgrade Watson Studio Runtimes:

Version requirements

All the components that are associated with an instance of Cloud Pak for Data must be installed at the same release. For example, if the Cloud Pak for Data control plane is at Version 5.0.3, you must upgrade Watson Studio Runtimes to Version 5.0.3.

Environment variables
The commands in this task use environment variables so that you can run the commands exactly as written.
  • If you don't have the script that defines the environment variables, see Setting up installation environment variables.
  • To use the environment variables from the script, you must source the environment variables before you run the commands in this task. For example, run:
    source ./cpd_vars.sh
Storage requirements
You don't need to specify storage when you upgrade Watson Studio Runtimes.

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 Watson Studio Runtimes. If this task is not complete, see System requirements.
The workstation from which you will run the upgrade is set up as a client workstation and the following command-line interfaces:
  • Cloud Pak for Data CLI: cpd-cli
  • OpenShift® CLI: oc
If this task is not complete, see Updating client workstations.
The Cloud Pak for Data control plane is upgraded. If this task is not complete, see Upgrading an instance of Cloud Pak for Data.
For environments that use a private container registry, such as air-gapped environments, the Watson Studio Runtimes software images are mirrored to the private container registry. If this task is not complete, see Mirroring images to a private container registry.
For environments that use a private container registry, such as air-gapped environments, the cpd-cli is configured to pull the olm-utils-v3 image from the private container registry. If this task is not complete, see Pulling the olm-utils-v3 image from the private container registry.
Ensure that the correct components are specified before running the upgrade. If this task is not complete, see Watson Studio Runtimes in the Services list.

Prerequisite services

Before you upgrade Watson Studio Runtimes, ensure that the following services are upgraded and running:

Procedure

Complete the following tasks to upgrade Watson Studio Runtimes:

  1. Upgrading the service
  2. Validating the upgrade
  3. What to do next

Upgrading the service

Important: The Operator Lifecycle Manager (OLM) objects for Watson Studio Runtimes were updated when you upgraded the Cloud Pak for Data platform. The cpd-cli manage apply-olm updates all of the OLM objects in the operators project at the same time.

To upgrade Watson Studio Runtimes:

  1. Log the cpd-cli in to the Red Hat® OpenShift Container Platform cluster:
    ${CPDM_OC_LOGIN}
    Remember: CPDM_OC_LOGIN is an alias for the cpd-cli manage login-to-ocp command.
  2. Update the custom resources for Watson Studio Runtimes.
    cpd-cli manage apply-cr \
    --components=ws_runtimes \
    --release=${VERSION} \
    --cpd_instance_ns=${PROJECT_CPD_INST_OPERANDS} \
    --license_acceptance=true \
    --upgrade=true
    Important: If you want to upgrade all existing runtimes automatically when you upgrade Watson Studio, specify the ws_runtimes component when you upgrade Watson Studio.

    If you do not specify the ws_runtimes component when you upgrade Watson Studio, only the default runtime is upgraded. You must upgrade the non-default runtimes manually.

Validating the upgrade

Watson Studio Runtimes is upgraded when the apply-cr command returns:
[SUCCESS]... The apply-cr command ran successfully

If you want to confirm that the custom resource status is Completed, you can run the cpd-cli manage get-cr-status command:

cpd-cli manage get-cr-status \
--cpd_instance_ns=${PROJECT_CPD_INST_OPERANDS} \
--components=ws_runtimes

What to do next

If you are using custom runtime images in Watson Studio, you must create and register these images again after you have upgraded Cloud Pak for Data to rebase the image with the latest Cloud Pak for Data runtime image. See Building custom images.

The service is ready to use. For details, see Notebook environments.
