We assume that all groups are present in the inventory, and quite obtuse
errors can result if any are not.
This change adds a precheck that checks for the presence of all expected
groups in the inventory for each service. It also introduces a common
service-precheck role that we can use for other common prechecks.

There are cases when a multinode deployment ends up in unusable
keystone public wsgi on some nodes.
The root cause is that keystone public wsgi doesn't find fernet
keys on startup - and then persists on sending 500 errors to any
requests - due to a race condition between
fernet_setup/fernet-push.sh and keystone startup.

For the CentOS 7 to 8 transition, we will have a period where both
CentOS 7 and 8 images are available. We differentiate these images via a
tag - the CentOS 8 images will have a tag of train-centos8 (or
master-centos8 temporarily).
To achieve this, and maintain backwards compatibility for the
openstack_release variable, we introduce a new 'openstack_tag' variable.
This variable is based on openstack_release, but has a suffix of
'openstack_tag_suffix', which is empty except on CentOS 8 where it has a
value of '-centos8'.

In source images, keystone-manage is installed to a virtualenv in

use PATH=/usr/bin:/bin. This results in the following error:

One cannot use IPv6 address to reference the image for docker like we
currently do, see: https://github.com/moby/moby/issues/39033
(docker_registry; docker API 400 - invalid reference format)
workaround: use hostname/FQDN
RabbitMQ may fail to bind to IPv6 if hostname resolves also to IPv4.
This is due to old RabbitMQ versions available in images.
IPv4 is preferred by default and may fail in the IPv6-only scenario.
This should be no problem in real life as IPv6-only is indeed IPv6-only.
Also, when new RabbitMQ (3.7.16/3.8+) makes it into images, this will
no longer be relevant as we supply all the necessary config.
See: https://github.com/rabbitmq/rabbitmq-server/pull/1982
For reliable runs, at least Ansible 2.8 is required (2.8.5 confirmed
to work well). Older Ansible versions are known to miss IPv6 addresses
in interface facts. This may affect redeploys, reconfigures and
upgrades which run after VIP address is assigned.

After all of the discussions we had on
"https://review.opendev.org/#/c/670626/2", I studied all projects that
have an "oslo_messaging" section. Afterwards, I applied the same method
that is already used in "oslo_messaging" section in Nova, Cinder, and
others. This guarantees that we have a consistent method to
enable/disable notifications across projects based on components (e.g.
Ceilometer) being enabled or disabled. Here follows the list of
components, and the respective changes I did.
* Aodh:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.
* Congress:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.
* Cinder:
It was already properly configured.
* Octavia:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.
* Heat:
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components
* Ceilometer:
Ceilometer publishes some messages in the rabbitMQ. However, the
default driver is "messagingv2", and not ''(empty) as defined in Oslo;
these configurations are defined in ceilometer/publisher/messaging.py.
Therefore, we do not need to do anything for the
"oslo_messaging_notifications" section in Ceilometer
* Tacker:
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components
* Neutron:
It was already properly configured.
* Nova
It was already properly configured. However, we found another issue
with its configuration. Kolla-ansible does not configure nova
notifications as it should. If 'searchlight' is not installed (enabled)
the 'notification_format' should be 'unversioned'. The default is
'both'; so nova will send a notification to the queue
versioned_notifications; but that queue has no consumer when
'searchlight' is disabled. In our case, the queue got 511k messages.
The huge amount of "stuck" messages made the Rabbitmq cluster
unstable.
https://bugzilla.redhat.com/show_bug.cgi?id=1478274https://bugs.launchpad.net/ceilometer/+bug/1665449
* Nova_hyperv:

* Vitrage

* Watcher
I created a mechanism similar to what we have in AODH, Cinder, Nova,

* Barbican
I created a mechanism similar to what we have in Cinder, Nova,
and others. I also added a configuration to 'keystone_notifications'
section. Barbican needs its own queue to capture events from Keystone.
Otherwise, it has an impact on Ceilometer and other systems that are
connected to the "notifications" default queue.
* Keystone
Keystone is the system that triggered this work with the discussions
that followed on https://review.opendev.org/#/c/670626/2. After a long
discussion, we agreed to apply the same approach that we have in Nova,
Cinder and other systems in Keystone. That is what we did. Moreover, we
introduce a new topic "barbican_notifications" when barbican is
enabled. We also removed the "variable" enable_cadf_notifications, as
it is obsolete, and the default in Keystone is CADF.
* Mistral:
It was hardcoded "noop" as the driver. However, that does not seem a
good practice. Instead, I applied the same standard of using the driver
and pushing to "notifications" queue if Ceilometer is enabled.
* Cyborg:
I created a mechanism similar to what we have in AODH, Cinder, Nova,
and others.
* Murano
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components

A common class of problems goes like this:
* kolla-ansible deploy
* Hit a problem, often in ansible/roles/*/tasks/bootstrap.yml
* Re-run kolla-ansible deploy
* Service fails to start
This happens because the DB is created during the first run, but for some
reason we fail before performing the DB sync. This means that on the second run
we don't include ansible/roles/*/tasks/bootstrap_service.yml because the DB
already exists, and therefore still don't perform the DB sync. However this
time, the command may complete without apparent error.
We should be less careful about when we perform the DB sync, and do it whenever
it is necessary. There is an argument for not doing the sync during a
'reconfigure' command, although we will not change that here.
This change only always performs the DB sync during 'deploy' and
'reconfigure' commands.

Currently, we have a lot of logic for checking if a handler should run,
depending on whether config files have changed and whether the
container configuration has changed. As rm_work pointed out during
the recent haproxy refactor, these conditionals are typically
unnecessary - we can rely on Ansible's handler notification system
to only trigger handlers when they need to run. This removes a lot
of error prone code.
This patch removes conditional handler logic for all services. It is
important to ensure that we no longer trigger handlers when unnecessary,
because without these checks in place it will trigger a restart of the
containers.

When running deploy or reconfigure for Keystone,
ansible/roles/keystone/tasks/deploy.yml calls init_fernet.yml,
which runs /usr/bin/fernet-rotate.sh, which calls keystone-manage
fernet_rotate.
This means that a token can become invalid if the operator runs
deploy or reconfigure too often.
This change splits out fernet-push.sh from the fernet-rotate.sh
script, then calls fernet-push.sh after the fernet bootstrap
performed in deploy.

Right now every controller rotates fernet keys. This is nice because
should any controller die, we know the remaining ones will rotate the
keys. However, we are currently over-rotating the keys.
When we over rotate keys, we get logs like this:
This is not a recognized Fernet token <token> TokenNotFound
Most clients can recover and get a new token, but some clients (like
Nova passing tokens to other services) can't do that because it doesn't
have the password to regenerate a new token.
With three controllers, in crontab in keystone-fernet we see the once a day
correctly staggered across the three controllers:
ssh ctrl1 sudo cat /etc/kolla/keystone-fernet/crontab
0 0 * * * /usr/bin/fernet-rotate.sh
ssh ctrl2 sudo cat /etc/kolla/keystone-fernet/crontab
0 8 * * * /usr/bin/fernet-rotate.sh
ssh ctrl3 sudo cat /etc/kolla/keystone-fernet/crontab
0 16 * * * /usr/bin/fernet-rotate.sh
Currently with three controllers we have this keystone config:
[token]
expiration = 86400 (although, keystone default is one hour)
allow_expired_window = 172800 (this is the keystone default)
[fernet_tokens]
max_active_keys = 4
Currently, kolla-ansible configures key rotation according to the following:
rotation_interval = token_expiration / num_hosts
This means we rotate keys more quickly the more hosts we have, which doesn't
make much sense.
Keystone docs state:
max_active_keys =
((token_expiration + allow_expired_window) / rotation_interval) + 2
For details see:
https://docs.openstack.org/keystone/stein/admin/fernet-token-faq.html
Rotation is based on pushing out a staging key, so should any server
start using that key, other servers will consider that valid. Then each
server in turn starts using the staging key, each in term demoting the
existing primary key to a secondary key. Eventually you prune the
secondary keys when there is no token in the wild that would need to be
decrypted using that key. So this all makes sense.
This change adds new variables for fernet_token_allow_expired_window and
fernet_key_rotation_interval, so that we can correctly calculate the
correct number of active keys. We now set the default rotation interval
so as to minimise the number of active keys to 3 - one primary, one
secondary, one buffer.
This change also fixes the fernet cron job generator, which was broken
in the following cases:
* requesting an interval of more than 1 day resulted in no jobs
* requesting an interval of more than 60 minutes, unless an exact
multiple of 60 minutes, resulted in no jobs
It should now be possible to request any interval up to a week divided
by the number of hosts.
