Standardize API health check endpoints

2026-04-12T13:02:28+00:00

Configure dedicated health check endpoints for Load Balancers Standardize health check paths in OpenStack and Grafana Ansible defaults to improve Load Balancer (HAProxy) reliability. The 'httpchk' configuration for the modified roles now uses dedicated health check endpoints (e.g., /healthcheck or /api/health) and enforces an HTTP 200 OK expectation. This ensures faster and more robust failure detection. Additionally, by moving health checks away from generic endpoints (such as OPTIONS /), application logs are now much cleaner. The log files will no longer be flooded every second with HAProxy probe entries like: "OPTIONS / HTTP/1.0" 200 94 0.000954 NOTE: The following services are exceptions to this standardization and still use the root endpoint (`/`) for health checks due to the lack of a dedicated health check middleware in their default API paste configuration: **cyborg_api**, **masakari**, **mistral_api**, **nova_api**, **octavia_api**, **placement**, **tacker**, **venus**, and **watcher**. Updated roles: * aodh * barbican * cinder * cloudkitty * cyborg * designate * etcd * glance * gnocchi * grafana * heat * horizon * influxdb * ironic * keystone * loadbalancer * magnum * manila * masakari * mistral * neutron * nova * nova-cell * octavia * opensearch * placement * rabbitmq * skyline * tacker * trove * venus * watcher * zun Change-Id: Ibbb9fda45a98565ab12e784bbef80be787bd6638 Signed-off-by: Piotr Milewski

etcd: deduplicate environments for containers

2023-11-29T17:43:22+00:00

* etcd service containers usually have a set of environment parameters required to boot the container. * The short-lived etcd bootstrap containers pass extra ETCD_INITIAL_* environment variables, but still need to pass the ones that the service containers use. * This uses ansible's `combine` filter to cut down on the duplication. * This is intended to be just a straightforward refactor.

etcd: Add support for more scenarios

2023-11-28T17:43:56+00:00

This commit addresses a few shortcomings in the etcd service: * Adding or removing etcd nodes required manual intervention. * The etcd service would have brief outages during upgrades or reconfigures because restarts weren't always serialised. This makes the etcd service follow a similar pattern to mariadb: * There is now a distiction between bootstrapping the cluster and adding / removing another member. * This more closely follows etcd's upstream bootstrapping guidelines. * The etcd role now serialises restarts internally so the kolla_serial pattern is no longer appropriate (or necessary). This does not remove the need for manual intervention in all failure modes: the documentation has been updated to address the most common issues. Note that there's repetition in the container specifications: this is somewhat deliberate. In a future cleanup, it's intended to reduce the duplication.
