When the active mgr changes, there may be user-created services
that also need to have their selector updated to point to the

Allow specifying daemon startup probes where we also allow configuring
liveness probes. Startup probes allow Rook to tolerate when Ceph daemons
occasionally take a long time to start up while not also making
Kubernetes liveness probes slower to detect runtime failures of daemons.
Startup probes are beta in Kubernetes 1.18, so we should not enable
probes by default for earlier Kubernetes versions.

For now, we must run the container with UID 0 and privileged for
multiple reasons:
* the rook binary writes ceph config to /var/lib/rook which is owned by
root
* it's difficult to use /etc/ceph since it will conflict with the
rook-ceph-override configmap AND is also owned by root since it's a
mounted configmap.
* using /etc/ceph might be possible but has other issues with rook's
exec package since the ceph config is built from /var/lib/rook

The cluster info is important context for the cluster controller to
create the cluster, and all the fields must be properly set.
A test cluster name was being set temporarily, resulting in
mons incorrectly getting the wrong cluster CR name. There is no
known issue from the temporary value, it was just exposed by
https://github.com/rook/rook/pull/8678 setting the value to a label.
Now the functions are more clearly named so only unit and
integration tests should be using the test value for the cluster
name where it is not important.

When private/public network have been defined in the Ceph rook cluster it is not
possible to configure properly the ip address of the liveness probe
for the manager.
Changes in the manager in Pacific introduced this regression.
This change replaces the http probe by a command probe, avoiding thus to
determine what is going to be the ip address of the manager before launching
the pod.

This commit is a large refactor on how the operator starts, stops and
how it starts various sub-components such as the ceph-csi driver. It
also refines the way we cancel orchestrations. We don't use breakpoints
anymore but send our self a SIGUP to reload our controller runtime
manager.
The reload will happen under different circonstances like:
* a new adminission controller secret is created/deleted/changed
* a CephCluster CR is edited
As mentioned earlier, the csi driver now has its own controller, just
like flex. It reacts to change in the operator config map for particular
ROOK_CSI_ fields.
A second new controller for the operator's general config has been
created, it manages:
* the logging level
* the ceph CLI command timeout
* the discovery daemon
The operator reacts much more rapidly to cancellation events by stopping
the manager's context and reloading it.

During disaster recovery/migration of a cluster, as part of the failover, the
kubernetes artifacts like deployment, PVC, PV, etc will be restored to a new
cluster by the admin. Even if the kubernetes objects are restored the
corresponding RBD/CephFS subvolume cannot be retrieved during CSI operations as
the clusterID and poolID are not the same in both clusters
This PR creates a mapping between Cluster ID and RBD Pool ID between
local cluster and peer cluster.

Both `ExecuteCommandWithOutputFileTimeout()` and
`ExecuteCommandWithOutputFile()` generate unnecessary system calls by
creating/reading/removing files where the stream output of the command
can simply be used. So sticking with `ExecuteCommandWithOutput()` and
`ExecuteCommandWithCombinedOutput()` for reading outputs is sufficient.

When there are multiple mgr daemons, the mgr sidecar owns reconciling
the services for the active mgr. However, for efficiency the sidecar
only reconciles the services if the active mgr changes. Now the operator
will also reconcile the mgr services to ensure that services are re-created
after being deleted, or otherwise in an incorrect state.

We now pass the networking spec to the clusterInfo so that the executor
can make the right decision on how to execute a command.
This is a small change that allows us to remove the CephBlockPool CR
since it's checking for rbd images. On a Multus deployment, the operator
does not have the network annotations, thus has no access to the OSD
network then rbd commands are hanging forever.
Signed-off-by: Sébastien Han <seb@redhat.com>
When the CephCluster is configured with Multus and multiple networks are
used to deploy Ceph some commands are failing to be executed from the
Operator. These commands, in particular, `radosgw-admin` ones need access
to the "ceph public network" to talk to OSDs. Unfortunately, the
Rook-Ceph Operator does not have the network annotations and thus
doesn't have the networks available and cannot reach OSDs. So the commands end
up hanging and eventually time out.
Applying the annotations to the Operator pod is possible but will result
in restarting the operator too and this should be avoided at all costs.
Also, applying the annotations beforehand is not possible since the
Multus declaration is in the CephCluster specification. So we would have
no idea what to do.
So the current approach runs a new sidecar container in the mgr pod to
act as a proxy for "some" ceph commands, only the `radosgw-admin` ones
for multi-site setup. This is a small container with admin access
running idle waiting for commands to be executed. In a sense, it is
similar to the toolbox but we didn't want to clearly expose it, so
running as a sidecar is quite nice.
Proxying command is obviously not always recommended since we add an
extra hop in the network path. Now each request has to go from the
operator pod to the API server to the remote pod to Ceph. Previously,
the command only goes from the operator to Ceph.
It's worth noting that external mode is not impacted since no rgw pod
is configured. This scenario is flexible and allows us to scale
pretty well since any CephCluster with Multus will see its mgr sidecar
deployed and can then talk to Ceph. We are not limited.
Signed-off-by: Sébastien Han <seb@redhat.com>
In the latest Ceph releases starting with v16.2.1, all clients are recommended
to be updated so they will have a security fix to connect with a secure
global ID. A health warning will be raised if any insecure clients are connected
and another health warning is raised if insecure clients are still allowed.
Rook will now disable allowing the insecure clients if the health warning
is not being raised to indicate that there are insecure clients still connected.
This means that upgraded clusters will not have this disabled until all the
daemons are updated.

The rook.io/v1 package was only an internal implementation detail and
does not have any CRDs that rely on it. The CRD deserialization should
handle the change in internal types without any issue. This separation
gives more flexibility for the storage providers to implement exactly
what is needed for their storage provider instead of forcing to use the
same types and risk affecting another storage provider.

If the cluster is external we want to periodically rehydrate the mgr
endpoint. This handles the scenarion where the active manager changes,
so we need to update the endpoint with the new IP address.
The create-external-cluster-resources.py script now requires an extra
permission to query the manager service so Rook can discover the active
one and its IP.
