Due to a bug in ansible, kolla-ansible deploy currently fails in nova
with the following error when used with ansible earlier than 2.8:

task path:
/home/zuul/src/opendev.org/openstack/kolla-ansible/ansible/roles/nova/tasks/discover_computes.yml:30

    "failed": true,
    "msg": "The field 'vars' has an invalid value, which
        includes an undefined variable. The error was:

This was caused by
https://review.opendev.org/#/q/I2915e2610e5c0b8d67412e7ec77f7575b8fe9921,
which hits upon an ansible bug described here:

We can work around this by not using an intermediary variable.

* Fix wsrep sequence number detection. Log message format is
  'WSREP: Recovered position: <UUID>:<seqno>' but we were picking out
  the UUID rather than the sequence number. This is as good as random.

* Add become: true to log file reading and removal since
  I4a5ebcedaccb9261dbc958ec67e8077d7980e496 added become: true to the
  'docker cp' command which creates it.

* Don't run handlers during recovery. If the config files change we
  would end up restarting the cluster twice.

* Wait for wsrep recovery container completion (don't detach). This
  avoids a potential race between wsrep recovery and the subsequent
  'stop_container'.

* Finally, we now wait for the bootstrap host to report that it is in
  an OPERATIONAL state. Without this we can see errors where the
  MariaDB cluster is not ready when used by other services.

There are now several good tools for deploying Ceph, including Ceph
Ansible and ceph-deploy. Maintaining our own Ceph deployment is a
significant maintenance burden, and we should focus on our core mission
to deploy OpenStack. Given that this is a significant part of kolla
ansible currently we will need a long deprecation period and a migration
path to another tool.

There is a race condition during nova deploy since we wait for at least
one compute service to register itself before performing cells v2 host
discovery.  It's quite possible that other compute nodes will not yet
have registered and will therefore not be discovered. This leaves them
not mapped into a cell, and results in the following error if the
scheduler picks one when booting an instance:

Host 'xyz' is not mapped to any cell

The problem has been exacerbated by merging a fix [1][2] for a nova race
condition, which disabled the dynamic periodic discovery mechanism in
the nova scheduler.

This change fixes the issue by waiting for all expected compute services
to register themselves before performing host discovery. This includes
both virtualised compute services and bare metal compute services.

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
============
None

Documentation Impact
====================
New documentation for the feature.

This performs the same as a deploy-bifrost, but first stops the
bifrost services and container if they are running.

This can help where a docker stop may lead to an ungraceful shutdown,
possibly due to running multiple services in one container.
