Teoman ONAY f8facde33a podman pids.max default value is 2048, docker's one is 4096 which are
sufficient for the default value (512) of rgw thread pool size.
But if its value is increased near to the pids-limit value,
it does not leave place for the other processes to spawn and run within
the container and the container crashes.

pids-limit set to unlimited regardless of the container engine.

This adds a `ExecStartPre=-/usr/bin/mkdir -p /var/log/ceph` in all
systemd service templates for all ceph daemon.
This is specific to RHCS after a Leapp upgrade is done. Indeed, the

Dimitri Savineau 47b7c00287 podman: always remove container on start
In case of failure, the systemd ExecStop isn't executed so the container
isn't removed. After a reboot of a failed node, the container doesn't
start because the old container is still present in created state.
We should always try to remove the container in ExecStartPre for this
situation.
A normal reboot doesn't trigger this issue and this also doesn't affect
nodes running containers via docker.
This behaviour was introduced by d43769d.

Because we need to manage legacy ceph-disk based OSD with ceph-volume
then we need a way to know the osd_objectstore in the container.

Note that this won't have any impact for ceph-volume lvm based OSD.

Rename docker_env_args fact to container_env_args and move the container
condition on the include_tasks call.

now included in the container_env_args variable.

Guillaume Abrioux 3e262e072b containers: use --cpus instead --cpu-quota
When using docker 1.13.1, the current condition:

```
{% if (container_binary == 'docker' and ceph_docker_version.split('.')[0] is version_compare('13', '>=')) or container_binary == 'podman' -%}
```

is wrong because it compares the first digit (1) whereas it should
compare the second one.
It means we always use `--cpu-quota` although documentation recommend
using `--cpus` when docker version is 1.13.1 or higher.

From the doc:
> --cpu-quota=<value>	Impose a CPU CFS quota on the container. The number of
> microseconds per --cpu-period that the container is limited to before
> throttled. As such acting as the effective ceiling.
> If you use Docker 1.13 or higher, use --cpus instead.

Guillaume Abrioux 8c8ec63633 container: use tmpfiles.d to creates /run/ceph
instead of using `RuntimeDirectory` parameter in systemd unit files,
let's use a systemd `tmpfiles.d` to ensure `/run/ceph`.

Explanation:

`podman` doesn't create the `/var/run/ceph` if it doesn't exist the time
where the container is run while `docker` used to create it.
In case of `switch_to_containers` scenario, `/run/ceph` gets created by
a tmpfiles.d systemd file; when switching to containers, the systemd
unit file complains because `/run/ceph` already exists

The better fix would be to ensure `/usr/lib/tmpfiles.d/ceph-common.conf`
is removed and only rely on `RuntimeDirectory` from systemd unit file parameter
but we come from a non-containerized environment which is already running,
it means `/run/ceph` is already created and when starting the unit to
start the container, systemd will still complain and we can't simply
remove the directory if daemons are collocated.

Applying and passing the OSD_BLUESTORE/FILESTORE on the fly is wrong for
existing clusters as their config will be changed.

Typically, if an OSD was prepared with ceph-disk on filestore and we
change the default objectstore to bluestore, the activation will fail.
The flag osd_objectstore should only be used for the preparation, not
activation. The activate in this case detects the osd objecstore which
prevents failures like the one described above.
