Description Sergio 2020-12-11 13:26:31 UTC
Description of problem:
When we configure a wrong registry pod image in the migrationcontroller resource, the migration is stuck forever.

Version-Release number of selected component (if applicable):
MTC 1.4.0

How reproducible:
Always

Steps to Reproduce:
1. In source cluster. Create namespace

$ oc new-project ocp-37313-registrybadimagetgt

2. In source cluster. Configure the migrationcontroller in order to use a wrong registry pod image

$ oc patch migrationcontroller migration-controller -n openshift-migration --type merge -p '{"spec":{"migration_registry_image":"docker.io/registry-fake","migration_registry_repo":"registry","migration_registry_version":"2"}}'


3. Create a migration plan to migrate the namespace created in step 1 and run the migration


Actual results:
The migration is stuck forever saying "waiting for pods to be ready" on the UI.


Expected results:
The migration should fail if we cannot create the registry pods, or at least show an error/warning telling the user that the registry pods cannot be created because of an ImagePullBackOff error and the cluster where the pods cannot be created.
