A combination of durable queues and classic queue mirroring can be used
to provide high availability of RabbitMQ. However, these options should
only be used together, otherwise the system will become unstable. Using
the flag ``om_enable_rabbitmq_high_availability`` will either enable
both options at once, or neither of them.
There are some queues that should not be mirrored:
* ``reply`` queues (these have a single consumer and TTL policy)
* ``fanout`` queues (these have a TTL policy)
* ``amq`` queues (these are auto-delete queues, with a single consumer)
An exclusionary pattern is used in the classic mirroring policy. This
pattern is ``^(?!(amq\\.)|(.*_fanout_)|(reply_)).*``

Kolla Ansible is switching to OpenSearch and is dropping support for
deploying ElasticSearch. This is because the final OSS release of
ElasticSearch has exceeded its end of life.
Monasca is affected because it uses both Logstash and ElasticSearch.
Whilst it may continue to work with OpenSearch, Logstash remains an
issue.
In the absence of any renewed interest in the project, we remove
support for deploying it. This helps to reduce the complexity
of log processing configuration in Kolla Ansible, freeing up
development time.

Render {{ openstack_service_workers }} for workers
of each openstack service is not enough. There are
several services which has to have more workers because
there are more requests sent to them.
This patch is just adding default value for workers for
each service and sets {{ openstack_service_workers }} as
default, so value can be overrided in hostvars per server.

- versioned endpoints e.g cinderv3 where I stripped the version

In services which use the Apache HTTP server to service HTTP requests,
there exists a TimeOut directive [1] which defaults to 60 seconds. APIs
which come under heavy load, such as Cinder, can sometimes exceed this
which results in a HTTP 504 Gateway timeout, or similar. However, the
request can still be serviced without error. For example, if Nova calls
the Cinder API to detach a volume, and this operation takes longer
than the shortest of the two timeouts, Nova will emit a stack trace
with a 504 Gateway timeout. At some time later, the request to detach
the volume will succeed. The Nova and Cinder DBs then become
out-of-sync with each other, and frequently DB surgery is required.
Although strictly this category of bugs should be fixed in OpenStack
services, it is not realistic to expect this to happen in the short
term. Therefore, this change makes it easier to set the Apache HTTP
timeout via a new variable.
An example of a related bug is here:
https://bugs.launchpad.net/nova/+bug/1888665
Whilst this timeout can currently be set by overriding the WSGI
config for individual services, this change makes it much easier.

When the internal VIP is moved in the event of a failure of the active
controller, OpenStack services can become unresponsive as they try to
talk with MariaDB using connections from the SQLAlchemy pool.
It has been argued that OpenStack doesn't really need to use connection
pooling with MariaDB [1]. This commit reduces the use of connection
pooling via two configuration options:
- max_pool_size is set to 1 to allow only a single connection in the
pool (it is not possible to disable connection pooling entirely via
oslo.db, and max_pool_size = 0 means unlimited pool size)
- lower connection_recycle_time from the default of one hour to 10
seconds, which means the single connection in the pool will be
recreated regularly
These settings have shown better reactivity of the system in the event
of a failover.

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.

Backport: stein
In the Stein release, cloudkitty switched the default storage backend
from sqlalchemy to influxdb. In kolla-ansible stein configuration, we
did not explicitly set the storage backend, and so we automatically
picked up this change. However, prior to
https://review.opendev.org/#/c/615928/ we did not have full support for
InfluxDB as a storage backend, and so this has broken the Rocky-Stein
upgrade (https://bugs.launchpad.net/kolla-ansible/+bug/1838641), which
fails with this during the DB sync:
ERROR cloudkitty InfluxDBClientError: get_list_retention_policies()
requires a database as a parameter or the client to be using a database
This change synchronises our default with cloudkitty's (influxdb), and
also provides an upgrade transition to create the influxdb database.
We also move the cloudkitty_storage_backend variable to
group_vars/all.yml, since it is used to determine whether to enable
influxdb.
Finally, the section name in cloudkitty.conf was incorrect - it was
storage_influx, but should be storage_influxdb.

This proposal will add support to Kolla-Ansible for Cloudkitty
InfluxDB storage system deployment. The feature of InfluxDB as the
storage backend for Cloudkitty was created with the following commit
https://github.com/openstack/cloudkitty/commit/
c4758e78b49386145309a44623502f8095a2c7ee
Problem Description
===================
With the addition of support for InfluxDB in Cloudkitty, which is
achieving general availability via Stein release, we need a method to
easily configure/support this storage backend system via Kolla-ansible.
Kolla-ansible is already able to deploy and configure an InfluxDB
system. Therefore, this proposal will use the InfluxDB deployment
configured via Kolla-ansible to connect to CloudKitty and use it as a
storage backend.
If we do not provide a method for users (operators) to manage
Cloudkitty storage backend via Kolla-ansible, the user has to execute
these changes/configurations manually (or via some other set of
automated scripts), which creates distributed set of configuration
files, "configurations" scripts that have different versioning schemas
and life cycles.
Proposed Change
===============
Architecture
------------
We propose a flag that users can use to make Kolla-ansible configure
CloudKitty to use InfluxDB as the storage backend system. When
enabling this flag, Kolla-ansible will also enable the deployment of
the InfluxDB via Kolla-ansible automatically.
CloudKitty will be configured accordingly to [1] and [2]. We will also
externalize the "retention_policy", "use_ssl", and "insecure", to
allow fine granular configurations to operators. All of these
configurations will only be used when configured; therefore, when they
are not set, the default value/behavior defined in Cloudkitty will be
used. Moreover, when we configure "use_ssl" to "true", the user will
be able to set "cafile" to a custom trusted CA file. Again, if these
variables are not set, the default ones in Cloudkitty will be used.
Implementation
--------------
We need to introduce a new variable called
`cloudkitty_storage_backend`. Valid options are `sqlalchemy` or
`influxdb`. The default value in Kolla-ansible is `sqlalchemy` for
backward compatibility. Then, the first step is to change the
definition for the following variable:
`/ansible/group_vars/all.yml:enable_influxdb: "{{ enable_monasca |
bool }}"`
We also need to enable InfluxDB when CloudKitty is configured to use
it as the storage backend. Afterwards, we need to create tasks in
CloudKitty configurations to create the InfluxDB schema and configure
the configuration files accordingly.
Alternatives
------------
The alternative would be to execute the configurations manually or
handle it via a different set of scripts and configurations files,
which can become cumbersome with time.
Security Impact
---------------
None identified by the author of this spec
Notifications Impact
--------------------
Operators that are already deploying CloudKitty with InfluxDB as
storage backend would need to convert their configurations to
Kolla-ansible (if they wish to adopt Kolla-ansible to execute these
tasks).
Also, deployments (OpenStack environments) that were created with
Cloudkitty using storage v1 will need to migrate all of their data to
V2 before enabling InfluxDB as the storage system.
Other End User Impact
---------------------
None.
Performance Impact
------------------
None.
Other Deployer Impact
---------------------
New configuration options will be available for CloudKitty.
* cloudkitty_storage_backend
* cloudkitty_influxdb_retention_policy
* cloudkitty_influxdb_use_ssl
* cloudkitty_influxdb_cafile
* cloudkitty_influxdb_insecure_connections
* cloudkitty_influxdb_name
Developer Impact
----------------
None
Implementation

Assignee
--------
* `Rafael Weingärtner <rafaelweingartne>`
Work Items
----------
* Extend InfluxDB "enable/disable" variable
* Add new tasks to configure Cloudkitty accordingly to these new
variables that are presented above
* Write documentation and release notes
Dependencies
============
