Steps to reproduce:

• Create a cluster named "my-cluster"

• Add an app repository

• It is associated with the cluster, yeah!

• Try to deploy an app from the catalog and you have "my-cluster" as an option

• Delete the cluster (not the repository)

• Try to deploy an app from the catalog and there are no cluster options (because there are no clusters available)

• Create a new cluster named "my-cluster"

• List app repositories - it says that the repository is assigned with 1 cluster

• Try to deploy an app from the catalog and there are still no cluster options :(, even though the list claimed that the repository was assigned to a cluster

Workaround:

• List the repositories and edit it

• Don't change a thing, just click "Save"

• Now the repository is actually assigned to the cluster and can actually deploy

Workarounds make me sad.
