Teoman ONAY 9b5d97adb9 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.

Guillaume Abrioux bab403b603 container/systemd: ensure /var/log/ceph exists
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
`/var/log/ceph` seems to be removed after the upgrade.
In order to work around this issue let's ensure the directory is present
before trying to start the containers with podman.

Guillaume Abrioux 5ba7824c55 container: force rm --storage on ExecStartPre
This is a workaround to avoid error like following:
```
Error: error creating container storage: the container name "ceph-mgr-magna022" is already in use by "4a5f674e113f837a0cc561dea5d2cd55d16ca159a647b7794ab06c4c276ef701"
```

that doesn't seem to be 100% reproducible but it shows up after a
reboot. The only workaround we came up with at the moment is to run
`podman rm --storage <container>` before starting it.

Dimitri Savineau 16cd183b9c podman: force log driver to journald
Since we've changed to podman configuration using the detach mode and
systemd type to forking then the container logs aren't present in the
journald anymore.

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.

Dimitri Savineau bd22f1d1ec docker: Add Requires on docker service
When using docker container engine then the systemd unit scripts only
use a dependency on the docker daemon via the After parameter.
But if docker is restarted on a live system then the ceph systemd units
should wait for the docker daemon to be fully restarted.

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.

Dimitri Savineau 91bef94b6c ceph-iscsi-gw: Update log directories bind mount
On containerized deployment we need to bind mount the ceph-iscsi
directory to avoid writing the logs in the container.
The /var/log/ceph directory isn't use by rbd-targe-api/gw services

Dimitri Savineau f49090df7e podman: Add systemd dependency on network.target
When using podman, the systemd unit scripts don't have a dependency
on the network. So we're not sure that the network is up and running
when the containers are starting.
With docker this behaviour is already handled because the systemd
unit scripts depend on docker service which is started after the
network.

Sébastien Han f203031f88 iscsi: expose /dev/log in the container
During its initialisation both rbd-target-api and rbd-target-gw try to
open /dev/log for their syslog handler. If the device is not present the
service fails to start. Thus expose /dev/log from the host in the
