With OpenSSL version prior 1.1.1 (like CentOS 7 with 1.0.2k), the -addext
doesn't exist.
As a solution, this uses the default openssl.cnf configuration file as a
template and add the subjectAltName in the v3_ca section. This temp openssl
configuration file is removed after the TLS certificate creation.
This patch also move the run_once statement at the block level.
add-osd: use container_exec_cmd fact from mon host
Because we're delegating the task to the first monitor node, we need to be
sure that the container_exec_cmd fact is the one from that node too otherwise
we could have a mismatch on the ceph-mon container name.

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.
infra: use dedicated variables for balancer status
The balancer status is registered during the cephadm-adopt, rolling_update
and swith2container playbooks. But it is also used in the ceph-handler role
which is included in those playbooks too.
Even if the ceph-handler tasks are skipped for rolling_update and
switch2container, the balancer_status variable is erased with the skip task
result.
infrastructure-playbooks: Get Ceph info in check mode
In the `set osd flags` block, run the Ceph commands that gather information
from the cluster (and don't make any changes to it) even when running in check
mode.
This allows the tasks that depend on the variables set by those tasks to
succeed in check mode.
When the rgw_multisite_proto variable is set to https then we shoudn't use
the IP address in the zone endpoints list but the node FQDN to match the
TLS certificate CN.
This refactor merges the two playbooks so we only have to maintain 1
playbook.
(Symlink the old purge-container-cluster.yml playbook for backward
compatibility).
Populating the ceph_mgr_modules list in the mgr_modules doesn't make sense
since that file is only executed if the list isn't empty or we're using the
dashboard.
We already have config override variables for existing block (like
ganesha_ceph_export_overrides, ganesha_log_overrides, etc...) or a
global one (ganesha_conf_overrides) but redefining the NFS_CORE_PARAM
block in that variable will erase all previous values (currently only
Bind_Addr).
If one a the monitor is out of the quorum then nothing prevents the upgrade
playbook to run.
We only check if we have at least three monitor nodes but we should also
check if those monitor nodes are correctly present in the quorum.

When calling the `ceph_key` module with `state: info`, if the ceph
command called fails, the actual error is hidden by the module which
makes it pretty difficult to troubleshoot.
The current code always states that if rc is not equal to 0 the keyring
doesn't exist.
`state: info` should always return the actual rc, stdout and stderr.
When running the switch-to-containers playbook with multisite enabled,
the fact "rgw_instances" is only set for the node being processed
(serial: 1), the consequence of that is that the set_fact of
'rgw_instances_all' can't iterate over all rgw node in order to look up
each 'rgw_instances_host'.
Adding a condition checking whether hostvars[item]["rgw_instances_host"]
is defined fixes this issue.
When monitors and rgw are collocated with multisite enabled, the
rolling_update playbook fails because during the workflow, we run some
radosgw-admin commands very early on the first mon even though this is
the monitor being upgraded, it means the container doesn't exist since
it was stopped.
This block is relevant only for scaling out rgw daemons or initial
deployment. In rolling_update workflow, it is not needed so let's skip
it.
When deploying dashboard in a cluster with rgw multisite deployed.
Due to the last rgw multisite refactor, we now expect the variable
`rgw_zonemaster` to be defined in the dict `rgw_instances`.
The idea here is to create that user on the cluster as soon as we have 1
`rgw_zonemaster` set to `true` in `rgw_instances`.
ceph-crash deployments is broken when ceph-ansible playbook is called
with --limit in containerized contexts since we don't set
`container_exec_cmd` on the first monitor.
When osd nodes are collocated in the clients group (HCI context for
instance), the current logic will exclude osd nodes since they are
present in the client group.
The best fix would be to exclude clients node only when they are not
member of another group but for now, as a workaround, we can enforce
the addition of osd nodes to fix this specific case.
0990ae41099d8b9d678f546fc8790033f421711f changed the filter in
selectattr() from 'match' to 'equalto' but due to an incompatibility with
the Jinja2 version for python 2.7 on el7 we must stick to using 'match'
filter.
This commit checks the length of `virtual_ips` doesn't exceed the length
of `groups[rgwloadbalancer_group_name]`.
It also ensure this variable is defined when
`groups[rgwloadbalancer_group_name]` contains at least one node.
While 2ca33641 fixed a bug in the way the `keepalived.conf.j2` template matched
hostnames to set the VRRP `MASTER`/`BACKUP` states, it also introduced a
regression in the case where `virtual_ips` is a list of more than one IP
address.
The previous behavior would result in each host in the `rgwloadbalancers` group
to be `MASTER` for one of the `virtual_ips`, but the new behavior caused the
first host to be `MASTER` for all the IP address in `virtual_ips`.
This is a workaround for an issue in ansible.
When trying to stop/mask/disable this service in one task, the stop
didn't actually happen, the task doesn't fail but for some reason the
container is still present and running.
Then the task starting the service in the role ceph-crash fails because
it can't start the container since it's already running with the same
name.

ceph-mon: Fix check mode for deploy monitor tasks
Skip the `get initial keyring when it already exists` task when both commands

Config the monitoring stack components api urls using a VIP
When dashboard_frontend_vip is provided, all the services should be
configured using the related VIP. A new VIP variable is added for
both prometheus and alertmanager: we're already able to properly
config the grafana vip using dashboard_frontend_vip variable.
This change adds the same variable for both prometheus and
alertmanager.
The `set_fact rgw_ports` task was failing due to a templating error, because
`hostvars[item].rgw_instances` is a list, but it was treated as if it was a
dictionary.
Another issue was the fact that the `unique` filter only applied to the list
being appended to `rgw_ports` instead of the entire list, which means it was
possible to have duplicate items.
Lastly, `rgw_ports` would have been a list of integers, but the `seport` module
expects a list of strings.
This commit fixes all of the issues above, allowing the `ceph-rgw-loadbalancer`
role to work on systems with SELinux enabled.
switch-to-containers: only chown corresponding files
When collocating daemons, if we chown all files under `/var/lib/ceph` it
can cause issues for the collocated daemons that wouldn't have been
migrated yet.
This commit makes the playbook chown only the files corresponding to the
daemon being migrated.
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.
rbdmirror: add retries/until when configuring mirroring
`configure_mirroring.yml` is called right after the daemon is started.
Sometimes, it can happen the first task in `configure_mirroring.yml` is
run while the daemon isn't yet ready, adding a retries/until on that
task should help to avoid causing the playbook to fail.
