Step 1

1. In <wc>/mapi/clusters/kustomization.yaml:

resources:
  - ../../../../../../../../bases/cluster
  - ../../../../../../../../bases/apps/default_step1

2. In staging.yaml > Update default_apps_release to 0.11.0.

This will annotate the apps with app-operator.giantswarm.io/paused: true.

Step 2

1. In <wc>/mapi/clusters/kustomization.yaml:

resources:
  - ../../../../../../../../bases/cluster
  - ../../../../../../../../bases/apps/default_step2

This will the delete default-apps-cloud-director App CR.

Step 3

1. In <wc>/mapi/clusters/kustomization.yaml (remove line *bases/apps/default*):

resources:
  - ../../../../../../../../bases/cluster_step3

2. In <wc>/mapi/clusters/cluster-extraconfig.yaml:

   • Remove internal.
   • [Tamarin] Remove .global.metadata.name (substituted in the bases).
   • [Leopard] Remove ...network.loadBalancer and ...network.loadBalancer.hostEntries

3. In <wc>.yaml in the substitute section:

   • Set cluster_release: 27.0.0
   • Remove default_apps_release

This will upgrade the cluster chart to releases and deploy default apps as part of the cluster chart.

Step 4

Final cleanup after all WCs are updated

• Delete ../../../../../../../../bases/apps/default*
• Delete bases/cluster
• Rename bases/cluster_step3 to bases/cluster
• Fix the WC kustomizations

1. In <wc>/mapi/clusters/kustomization.yaml (remove _step3 in resource):

resources:
