#Image Registry Replacement

For cross-cluster and cross-platform recovery scenarios, use this procedure to restore application images so they can pull from the correct repository after migration.

• Image repository migration: When the image repository changes, update application image references to the new repository.
• Image synchronization: When synchronizing images to other projects within the repository (for example, promoting from test to production), update application image references to the new version.

#Procedure

1. Before performing the recovery task, create a ConfigMap that maps old to new image repositories. Replace the placeholders in the following example and save as change-registry-config.yaml.

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: change-registry-config
     namespace: cpaas-system
     labels:
       velero.io/plugin-config: ""
       alauda.io/change-registry: RestoreItemAction
   data:
     old: <Old Image Repository Address>
     new: <New Image Repository Address>

2. On a control-plane node of the target cluster, create the ConfigMap:

   kubectl apply -f change-registry-config.yaml

3. After creation, continue with the application recovery task.
