When using TLS on the ceph dashboard or grafana services, we can provide
the TLS certificate and key.
Those files should be present on the ansible controller and they will be
copyied to the right node(s).
In some situation, the TLS certificate and key could be already present
on the target node and not on the ansible controller.
For this scenario, we just need to copy the files locally (on each remote
host).
This patch adds the dashboard_tls_external variable (with default to
false) to allow users to achieve this scenario when configuring this
variable to true.
In addition of 155e2a2, the active mds daemons isn't stop/start
correctly as opposed as the other services so that daemon doesn't come
back after the upgrade.
Due to [1], ceph-volume has now a dependency on pyyaml but it's not
installed by default via the package dependency.
This patch only add the required package on non containerized
deployment and as temporary workaround for the CI.
The dashboard upgrade workflow should do the same process than the ceph
upgrade otherwise any systemd unit modification won't be apply on the
monitoring/dashboard stack.
During the daemon upgrade we're
- stopping the service when it's not containerized
- running the daemon role
- start the service when it's not containerized
- restart the service when it's containerized
This implementation has multiple issue.
1/ We don't use the same service workflow when using containers
or baremetal.
2/ The explicity daemon start isn't required since we'are already
doing this in the daemon role.
3/ Any non backward changes in the systemd unit template (for
containerized deployment) won't work due to the restart usage.
This patch refacts the rolling_update playbook by using the same service
stop task for both containerized and baremetal deployment at the start
of the upgrade play.
It removes the explicit service start task because it's already included
in the dedicated role.
The service restart tasks for containerized deployment are also
removed.
Finally, this adds the missing service stop task for ceph crash upgrade
workflow.
The iscsigws restart scripts for tcmu-runner and rbd-target-{api,gw}
services only call the systemctl restart command.
We don't really need to copy a shell script to do it when we can use
the ansible service module instead.
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.
Set the cephadm cmd as a fact instead of rewriting the same command
over and over.
This also fix an issue when using docker as container engine because
the --docker cephadm parameter should be use before the subcommand
not after.
The ceph-dashboard role is executed on the mgr nodes so the TLS cert/key
files are copied to those nodes.
But we are running importing the cert/key files into the ceph
configuration on the monitor.
This is a partial revert of b38019e because we don't want to execute
the whole play on the monitor otherwise if we have some empty group
like rgws or mdss then the orchestrator commands will still be
executed.
Instead we should keep the real target group name at play level and
delegate the orchestator commands to the monitor. The whole play
will be skipped is the group is empty.
Print a message at the end of the playbook to inform users that they
don't have to user ceph-ansible playbooks anymore as everything else
need to be done via cephadm (day 2 operation).
When reporting the orchestrator service/daemon list at the end of the
playbook, we can use the --refresh option otherwise we could have
an outdated output.
Like rolling_update or switch2container playbooks, we need to set/unset
some osd flags before and after the OSD daemons adoption.
This also adds a task for waiting for clean pgs at then of an OSd node.
cephadm uses default value for dashboard container images which need to
be customized by ansible for upstream or downstream purpose.
This feature wasn't present when cephadm-adopt.yml has been designed.
Also set the container_image_base variable for upgrade purpose.

facts: explicitly disable facter and ohai
By default, ansible gathers facts from facter and ohai if installed on
the remote nodes, given we don't need them, let's exclude these facts
from our facts gathering
When rgw and osd are collocated, the current workflow prevents from
scaling out the radosgw_num_instances parameter when rerunning the
playbook.
The environment file used in the rgw systemd template is rendered when
executing the `ceph-rgw` role but during a new run of the playbook (in
order to scale out rgw instances), handlers are triggered from `ceph-osd`
role which is run before `ceph-rgw`, therefore it tries to start the new
rgw daemon whereas its corresponding environment file hasn't been
rendered yet and fails like following:
```
ceph-radosgw@rgw.ceph4osd3.rgw1.service failed to run 'start-pre' task: No such file or directory
```
This commit moves the tasks generating this file in `ceph-config` role
so it is generated early.

dashboard: configure mgr backend before restart
We need to set the mgr dashboard server ip address before restarting the
dashboard module otherwise we can try to bind the dashboard module on an
already used address.
We already do this configuration for the dashboard port value and ssl
setup so we should do the same for server address too.
This commit makes the playbook copying self-signed generated certificate
to monitors.
When mons and mgrs are deployed on dedicated nodes the playbook will
fail when trying to import certificate and key files since they are
generated on mgrs whereas we try to import them from a monitor.

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.

travis: use tests/requirements.txt
Explicitly install ansible-lint pytest pytest-cov via pip results of a
specific pytest version (4.3.1) which is not supported for pytest-cov
(2.10).
Because we are already defining a specific pytest version in the tests
requirements then we can install all the python dependencies from that
file and remove this from the pip install command.
Since we only have one scenario since nautilus then we can just move
the container start command from ceph-osd-run.sh to the systemd unit
service.
As a result, the ceph-osd-run.sh.j2 template and the
ceph_osd_docker_run_script_path variable are removed.

debian/uca: remove the handler notification
The "update apt cache" in the ceph-handler role was never called and the
handler trigger after adding the uca repository doesn't exist at all.
Instead of using a handler for that we can just set the update_cache
parameter to true like the other apt_repository tasks.
container: inspect Id field instead of RepoDigests
When a container image managed by podman isn't tag anymore then the
RepoDigests field when inspecting the image doesn't return any value.
This is different from docker workflow and it breaks the ceph-ansible
container upgrade when collocated multiple services and using a non
fix container tag (like latest or 4).

ceph-nfs: add stable noarch repository
When using the stable nfs ganesha repository, we need have both arch

Currently the noarch repository is missing which cause the non
containerized deployment to fail.
setting attributes with empty string is a bad user input.
Also, removing `rule_name` attribute when creating a code erasure pool.
(this rule isnt intended for code erasure pool type).
facts: always set ceph_run_cmd and ceph_admin_command
always set these facts on monitor nodes whatever we run with `--limit`.
Otherwise, playbook will fail when using `--limit` on nodes where these
facts are used on a delegated task to monitor.
