Upgrading RStudio Server Runtimes from Version 5.2 to Version 5.4

Information you need to complete this task

Review the following information before you upgrade RStudio Server Runtimes:

Version requirements

All the components that are associated with an instance of IBM Software Hub must be installed at the same release. For example, if the IBM Software Hub control plane is at Version 5.4.0, you must upgrade RStudio Server Runtimes to Version 5.4.0.

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

Common core services

RStudio Server Runtimes requires the IBM Software Hub common core services.

If the common core services are not at the correct version in the operands project for the instance, the common core services are automatically upgraded when you upgrade RStudio Server Runtimes. The common core services upgrade increases the amount of time the upgrade takes to complete.

Before you begin

Private container registry

If your environment uses a private container registry (for example, your cluster is air-gapped), this task assumes that the following tasks are complete:

1. The RStudio Server Runtimes software images are mirrored to the private container registry.

   Where to find more information
   If this task is not complete, see Mirroring images to a private container registry.

2. The cpd-cli is configured to pull the olm-utils-v4 image from the private container registry.

   If this task is not complete, see Pulling the olm-utils-v4 image from the private container registry.

Cluster-scoped resources

This task assumes that the cluster-scoped resources, such as custom resource definitions, cluster roles, and cluster role bindings, were updated.

Where to find more information
If this task is not complete, see Updating the cluster-scoped resources for the platform and services.

Image pull secrets

This task assumes that the secrets that contain the image pull credentials for the instance exist.

Where to find more information
If this task is not complete, see Creating image pull secrets for an instance of IBM Software Hub.

Prerequisite services

Before you upgrade RStudio Server Runtimes, ensure that the following services are upgraded and running:

• Watson Studio

Procedure

Complete the following tasks to upgrade RStudio Server Runtimes:

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

Upgrading the service

To upgrade RStudio Server 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 operator and custom resource for RStudio Server Runtimes.

   cpd-cli manage install-components \
   --license_acceptance=true \
   --components=rstudio \
   --release=${VERSION} \
   --patch_id=${PATCH_ID} \
   --operator_ns=${PROJECT_CPD_INST_OPERATORS} \
   --instance_ns=${PROJECT_CPD_INST_OPERANDS} \
   --image_pull_prefix=${IMAGE_PULL_PREFIX} \
   --image_pull_secret=${IMAGE_PULL_SECRET} \
   --upgrade=true

Validating the upgrade

[SUCCESS]... The install-components 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=rstudio
