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 a deployment where Prometheus is enabled and
Alertmanager is disabled the task "Copying over
prometheus config file" in
'ansible/roles/prometheus/tasks/config.yml' will
fail to template the Prometheus configuration file
'ansible/roles/prometheus/templates/prometheus.yml.j2'
as the variable 'prometheus_alert_rules' does not
contain the key 'files'. This commit fixes this bug.

As part of the effort to implement Ansible code linting in CI
(using ansible-lint) - we need to implement recommendations from
ansible-lint output [1].
One of them is to stop using local_action in favor of delegate_to -
to increase readability and and match the style of typical ansible
tasks.

Introduce kolla_address filter.

Add AF config to vars.
Address contexts:
- raw (default): <ADDR>
- memcache: inet6:[<ADDR>]
- url: [<ADDR>]
Other changes:
globals.yml - mention just IP in comment
prechecks/port_checks (api_intf) - kolla_address handles validation
3x interface conditional (swift configs: replication/storage)
2x interface variable definition with hostname
(haproxy listens; api intf)
1x interface variable definition with hostname with bifrost exclusion
(baremetal pre-install /etc/hosts; api intf)
neutron's ml2 'overlay_ip_version' set to 6 for IPv6 on tunnel network
basic multinode source CI job for IPv6
prechecks for rabbitmq and qdrouterd use proper NSS database now
MariaDB Galera Cluster WSREP SST mariabackup workaround
(socat and IPv6)
Ceph naming workaround in CI
TODO: probably needs documenting
RabbitMQ IPv6-only proto_dist
Ceph ms switch to IPv6 mode
Remove neutron-server ml2_type_vxlan/vxlan_group setting
as it is not used (let's avoid any confusion)
and could break setups without proper multicast routing
if it started working (also IPv4-only)
haproxy upgrade checks for slaves based on ipv6 addresses
TODO:
ovs-dpdk grabs ipv4 network address (w/ prefix len / submask)
not supported, invalid by default because neutron_external has no address
No idea whether ovs-dpdk works at all atm.
ml2 for xenapi
Xen is not supported too well.
This would require working with XenAPI facts.
rp_filter setting
This would require meddling with ip6tables (there is no sysctl param).
By default nothing is dropped.
Unlikely we really need it.
ironic dnsmasq is configured IPv4-only
dnsmasq needs DHCPv6 options and testing in vivo.
KNOWN ISSUES (beyond us):
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.
See: https://github.com/ansible/ansible/issues/63227
Bifrost Train does not support IPv6 deployments.

This commit follows up the work in Kolla to provide deploy and configure the
Prometheus blackbox exporter.
An example blackbox-exporter module has been added (disabled by default)
called os_endpoint. This allows for the probing of endpoints over HTTP
and HTTPS. This can be used to monitor that OpenStack endpoints return a status
code of either 200 or 300, and the word 'versions' in the payload.
This change introduces a new variable `prometheus_blackbox_exporter_endpoints`.
Currently no defaults are specified because the configuration is heavily
dependent on the deployment.

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.

Having all services in one giant haproxy file makes altering
configuration for a service both painful and dangerous. Each service
should be configured with a simple set of variables and rendered with a
single unified template.
Available are two new templates:
* haproxy_single_service_listen.cfg.j2: close to the original style, but
only one service per file
* haproxy_single_service_split.cfg.j2: using the newer haproxy syntax
for separated frontend and backend
For now the default will be the single listen block, for ease of
transition.

This patch extends the prometheus role for being able
to deploy the prometheus-alertmanager[0] container.
The variable enable_prometheus_alertmanager
decides if the container should be deployed and enabled.
If enabled, the following configuration and actions are performed:
- The alerting section on the prometheus-server configuration
is added pointing the prometheus-alertmanager host group as targets.
- HAProxy is configured to load-balance over the prometheus-alertmanager
host group. (external/internal).
Please note that a default (dummy) configuration is provided, that
allows the service to start, the operator should extend it via a node custom config
