feat(instance): liveness probe isolation checker (#7466)%0A%0AEnhances the liveness probe logic for primary instances in HA clusters%0Ato detect network isolation scenarios.%0A%0AThe probe first checks if the Pod can reach the API server. If the API%0Aserver is unreachable, it then attempts to contact peer PostgreSQL%0Ainstances in the same cluster via a REST entrypoint.%0A%0AIf neither the API server nor any replicas are reachable, the liveness%0Aprobe fails, prompting Kubernetes to restart the Pod.%0A%0AUpon restart, the instance manager will refuse to start PostgreSQL, as%0Ait cannot download the Cluster definition—preventing unsafe behavior in%0Aisolated environments.%0A%0AThis behavior applies only to primary instances in clusters with HA%0Areplicas and is disabled by default.%0A%0ACloses: #7465%0A%0ASigned-off-by: Leonardo Cecchi <[email protected]>%0ASigned-off-by: Armando Ruocco <[email protected]>%0ASigned-off-by: Niccolò Fei <[email protected]>%0ASigned-off-by: Gabriele Bartolini <[email protected]>%0ASigned-off-by: Marco Nenciarini <[email protected]>%0ACo-authored-by: Armando Ruocco <[email protected]>%0ACo-authored-by: Niccolò Fei <[email protected]>%0ACo-authored-by: Gabriele Bartolini <[email protected]>%0ACo-authored-by: Marco Nenciarini <[email protected]>
