Following the Ceph OSD rework, my test environment regularly failed to

was chown'ing the log and data directories could finish. Pods failed to
start for an arbitrarily long time before starting successfully. This
was a manifestation of a race condition identified in Ceph monitors in

Create a Ceph operator-level method to create an init container that
will chown the necessary directories for all Ceph daemons (any daemon
which runs as the ceph:ceph user-and-group). Also add this container to
expectations for Ceph pod templates in unit tests.

On rare occasion, the ceph checks might not be 100% correct and the user
might decide to force an upgrade anyway.
Correctly, if we are in an upgrade, we perform `ok-to-stop` check for
each daemon, if one of them fails, we retry and eventually fail.
They are corner-cases where users would like to force the upgrade anyway.
Enhance the new CR property: "skipUpgradeChecks: true".

this patch adds two new related features. first, it removes the
requirement that all monitor deployments be pinned to nodes using node
selector. this is allowed when not using host networking and when PVC
storage is used. the second feature introduced in this patch is the
elimination of the Rook scheduler for placing monitors that continue to
use the node selector by using canary pods to that are scheduled by k8s,
after which Rook uses the scheduling results to pin the monitors to
nodes.

When a cluster is updated with a different image version, this triggers
a serialized restart of all the pods. Prior to this commit, no safety
check were performed and rook was hoping for the best outcome.
Now before doing restarting a daemon we check it can be restarted. Once
it's restarted we also check we can pursue with the rest of the
platform. For instance, with monitors we check that they are in quorum,
for OSD we check that PGs are clean and for MDS we make sure they are
all active.

Add a `rook-version` label to all controller resources used by Ceph:
deployments, daemonsets, and jobs. Labels are added to controller
resources only and not to the pod templates within because changing pod
templates causes updates due to the label change. The controller

therefore don't cause an unnecessary upgrade.

The Ceph mon flag `--public-bind-addr` does not keep the same port as
the previous daemon run when the port is left off the flag's value. A
port is undesired since that could interfere with Nautilus' msgr2
protocol, so instead configure the mon's services to forward the default
bind port on pods (6789) to the mon endpoint's port. The endpoint port
will be 6789 for new mons, but it may be 6790 for legacy clusters.

corresponding deployment. This will mean that the secrets do not need to
be micromanaged. When the deployment is deleted, the secret is also

This commit introduces the necessary changes to support the new
messenger feature coming with Ceph Nautilus (currently in development).
What changes? Now the monitor listens on two port:
* old 6789 for messenger v1, which will help us support older client
(e,g: krbd)
* new 3300 for messengers v2, which brings new improvement in the
messaging layer. This new transport layer brings numerous advantages
such as encryption improvement, speed improvement, pluggable nature to
support different network stack than TCP and many more.
We still have one Service IP, however it has 2 ports, see:
```
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
rook-ceph-mon-a ClusterIP 10.106.217.160 <none> 3300/TCP,6789/TCP 4h
rook-ceph-mon-b ClusterIP 10.99.36.175 <none> 3300/TCP,6789/TCP 4h
rook-ceph-mon-c ClusterIP 10.108.220.74 <none> 3300/TCP,6789/TCP 4h
````
The `ceph.conf` has changed and we don't force the port when using an IP
address (public addr etc). Ceph, depending on its version will naturally
start the monitors on their right port, 6789.
A new --ceph-version-name CLI argument has been added to the Rook binary
so that when the pod starts it passes the ceph version name and the
configuration of the ceph.conf, as well as daemon startup flags, happen
properly.
Given that the Rook Operator remembers the port of all the monitors it
deployed (through Pod definition), this change is not an issue and will
maintain backward compatibility.
Note that to test this you must build rook with dev container image,
which contains the dev Nautilus version. So you should do something
like:
`make -j4 BASEIMAGE='ceph/daemon-base:latest-master' IMAGES='ceph' build`

The pod spec for the mgr changed quite a bit, and instead of updating
the unit tests of questionable use, some additional unit test tools
applicable to any Ceph daemon have been added and used with the mgr. The
mgrs unit tests should now be more useful and get in the way of devs
less, and they can be used by other daemons later.

Make the Rook config-init unnecessary for mons, and remove that init
container. Perform all mon configuration steps in the operator, and set
up the mon pods and k8s environment such that only Ceph containers are
needed for running mons.
This should help streamline changes to the mons, as there will be no
need to change the `daemon/mon` code or `cmd/rook/ceph` code with mon
changes in the future.
This work starts to lay the groundwork for supporting the
`design/ceph-config-updates.md` design.
Notable new bits:
Create a keyring secret store helper for storing dameon keyrings, and
use it to store the mon keyring. Mon pods mount the keyring into a
k8s secret-backed volume.
Create a configmap store for the Ceph config file which can be mounted
into pods/containers directly to /etc/ceph/ceph.conf. Also store
individual mon_host and mon_initial_members values which can be mapped
into pods as environment variables and used in Ceph commandline flags,
enabling the mon pods to have the most up-to-date information about the
mon cluster when restarting and without need for operator intervention.

Use init containers to create configuration for Ceph mgrs. There is only
one init container in this design. The init container calls the Rook
binary to create Ceph config files which are then shared with the mds
daemon main container.
Once this init is run, the main mds daemon is run. Leaving room to use
the Ceph-versioned image in the future, call `ceph-mds --foreground ...`
to run the Ceph mds.
The refactor to using an init container also necessitated refactoring
the mdses replicaset implementation to a deployment-per-pod
implementation due to a chicken-egg problem. With a single container (in
the before times) the Rook binary was able to call the ceph-mds daemon
with an id generated from the pod name. Since the pod name is not known
before runtime, and the id is one of the few params that must be
specified to Ceph daemons on run, it is necessary to know the id
beforehand; thus the move to a deployment architecture following the
likes of the mon and mgr daemons.
