Adding ceph storage results in "ambiguous relation" error

[Barry Price]

After following the instructions here to deploy kubernetes and the extra ceph units:

https://jaas.ai/canonical-kubernetes

> Next relate the storage cluster with the Kubernetes cluster:

> juju add-relation kubernetes-master ceph-mon

However:

$ juju add-relation kubernetes-master ceph-mon
ERROR ambiguous relation: "kubernetes-master ceph-mon" could refer to "kubernetes-master:ceph-client ceph-mon:client"; "kubernetes-master:ceph-storage ceph-mon:admin"
$

This is with Juju 2.6.8 on Ubuntu 16.04.

Hi Barry, it looks like those instructions have fallen out of sync with our official docs @ https://ubuntu.com/kubernetes/docs/storage. Please refer to those instead.

We have a docs bug open to correct this (and similar) discrepancies at https://github.com/charmed-kubernetes/kubernetes-docs/issues/294.

Thanks for reporting this! I'll close this bug in lieu of the docs bug above.
