Hi all,

We are trying to install Airship, but ran into some issues I’d like to bring up here. Specifically, we base our config on treasuremap tag v19.02.04 and see the following two problems:

i) The ceph-rbd-provisioner pod tries to use service kube-dns although only coredns is deployed by Airship.

Log:

kubectl logs -n ceph ceph-rbd-provisioner-85f5b5bb8b-8vzc7

I0207 11:21:51.007104 1 leaderelection.go:156] attempting to acquire leader lease...

I0207 11:21:51.014035 1 leaderelection.go:178] successfully acquired lease to provision for pvc ucp/mysql-data-mariadb-server-0

E0207 11:21:51.249161 1 provision.go:199] error getting kube-dns service: services "kube-dns" not found

I0207 11:22:16.379111 1 leaderelection.go:204] stopped trying to renew lease to provision for pvc ucp/mysql-data-mariadb-server-1, timeout reached

We are wondering if that is a version selection problem (non-matching Kubernetes and DNS service), but we haven’t touched the versions.yaml.

ii) The ceph-rgw pod is not started on the Genesis node (nor on any other node; this is during an early phase before other nodes are provisioned); no related error in logs; all other ceph pods seem to be there. As a result, PVCs are not bound and database pods cannot start.

Did anybody run into this issue before or could point us in the right direction?

Thanks a lot!
