Sébastien Han 93b2448619 ceph: refactor rgw bootstrap
This commit does multiple things:

* remove support for AllNodes where we would deploy one rgw per node on
all the nodes.
* a transition path is implemented in the code so that if someone has an
existing deployment, daemonsets will be removed and replaced by an
deployments.
* when using "instances", each rgw deployed has its own key which makes
Ceph reporting the exact number of rgw running, see:

  services:
    mon: 3 daemons, quorum a,b,c (age 12h)
    mgr: a(active, since 12h)
    osd: 3 osds: 3 up (since 12h), 3 in (since 12h)
    rgw: 3 daemons active (my.store.a, my.store.b, my.store.c)

Major Themes

Action Required

Notable Features

  • Creation of storage pools through the custom resource definitions (CRDs) now allows users to optionally specify deviceClass property to enable distribution of the data only across the specified device class. See Ceph Block Pool CRD for an example usage

Ceph

  • Rook can now be configured to read "region" and "zone" labels on Kubernetes nodes and use that information as part of the CRUSH location for the OSDs.
  • Rgw pods have liveness probe enabled
  • Rgw is now configured with the Beast backend as of the Nautilus release
  • OSD: newly updated cluster from 0.9 to 1.0.3 and thus Ceph Nautilus will have their OSDs allowing new features for Nautilus
  • Rgw instances have their own key and thus are properly reflected in the Ceph status

Breaking Changes

Known Issues

Deprecations

Ceph

  • For rgw, when deploying an object store with object.yaml, using allNodes is not supported anymore, a transition path has been implemented in the code though. So if you were using allNodes: true, Rook will replace each daemonset with a deployment (one for one replacement) gradually. This operation will be triggered on an update or when a new version of the operator is deployed. Once complete, it is expected that you edit your object CR with kubectl -n rook-ceph edit cephobjectstore.ceph.rook.io/my-store and set allNodes: false and instances with the current number of rgw instances.
