Upgrade Exoscale clusters to component version v9

When upgrading to component version v9 for Exoscale clusters, the following breaking change may require manual changes in the Project Syn config of existing clusters:

The config changes outlined in this guide must be applied at the same time as the upgrade to component version v9.
We will publish a guide to migrate existing clusters to use instance pools in a future version of this component.

Steps

  1. Get a clone of the tenant repo of the clusters that you want to upgrade to component version v9.

  2. Make sure component openshift4-terraform is updated to at least v9.0.0 so the variable infra_use_instancepool exists

  3. Set parameters.openshift4_terraform.variables.infra_use_instancepool to true for existing clusters which have been setup with instancepools for the worker and infra nodes.

    The variable infra_use_instancepool has no effect for clusters which set variabl use_instancepools to false.

  4. Commit the changes
