Instead of having a variable for each flags, could we just have an emptyImageFlags and use it for all parameters?

I'll need to make sure I have this logic wired in the new implementation of ComputeImage I'm working on

I wonder if we want to setup traefik / nginx with hub ports in all cases or not. The problem is that if the user decides to scale the number of replicas of the hub API, then traefik / nginx config is not ready.

This would work for Hub XML-RPC API since we can have at most 1 replica, but I would see a Connection.GetReplicasCount("hub-xmlrpc-api"). This could also be reused for CoCo containers in the future.

During a migration to kubernetes the server is deployed after the rsync to prepare the SSL secrets and PVC. This has the nasty effect to corrupt the synchronized data with a too recent catalog version ID. This would let the DB migration to fail starting the old postgresql server. To workaround this, move the data to the the backup place after the rsync instead of the begining of the db upgrade.
After the k8s migration the pod has been started again since the initial connection creation. We need to reset the connection to not search for the old pod name.
Some pods require a long time to run. This is the case for the DB upgrade finalization that runs a potentially long reindex.
Migration deploys the helm chart multiple times. Identifying which revision corresponds to which step in helm history is hard without a description.
