Kubernetes pod never gets ready
I finally solved the problem. In the yaml files describing the Replication Controllers, I was using keyring: in the volume section:
keyring: "ceph.client.admin.keyring" After I generated a Ceph secret and changed the yaml files to use secretRef:
secretRef: name: "ceph-secret"Kubernetes was able to map and mount the Ceph volumes and the pods began to start normally. I don't know why using keyring: doesn't work in this case.
