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

Developer Impact
----------------
None
Implementation

* Add new tasks to configure Cloudkitty accordingly to these new
variables that are presented above
* Write documentation and release notes

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.

Some kolla-ansible jobs failed due to using external mirrors
instead of local ones.
This was due to not using the template override provided by kolla.
This patch fixes that.

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.

During an upgrade, nova pins the version of RPC calls to the minimum
seen across all services. This ensures that old services do not receive
data they cannot handle. After the upgrade is complete, all nova
services are supposed to be reloaded via SIGHUP to cause them to check
again the RPC versions of services and use the new latest version which
should now be supported by all running services.
Due to a bug [1] in oslo.service, sending services SIGHUP is currently
broken. We replaced the HUP with a restart for the nova_compute
container for bug 1821362, but not other nova services. It seems we need
to restart all nova services to allow the RPC version pin to be removed.
Testing in a Queens to Rocky upgrade, we find the following in the logs:
Automatically selected compute RPC version 5.0 from minimum service
version 30
However, the service version in Rocky is 35.
There is a second issue in that it takes some time for the upgraded
services to update the nova services database table with their new
version. We need to wait until all nova-compute services have done this
before the restart is performed, otherwise the RPC version cap will
remain in place. There is currently no interface in nova available for
checking these versions [2], so as a workaround we use a configurable
delay with a default duration of 30 seconds. Testing showed it takes
about 10 seconds for the version to be updated, so this gives us some
headroom.
This change restarts all nova services after an upgrade, after a 30
second delay.

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.
