Rollout & Availability

Pod non disponibili durante un rollout

kube_deployment_status_replicas_available{namespace!~"kube-.*|openshift-.*"}
< kube_deployment_spec_replicas{namespace!~"kube-.*|openshift-.*"}

Pod in stato Terminating a lungo (stuck)

kube_pod_deletion_timestamp{namespace!~"kube-.*|openshift-.*"} > 0
and
(time() - kube_pod_deletion_timestamp) > 300

Availability: % pod Ready sul totale desired

sum by (namespace, deployment) (kube_deployment_status_replicas_available)
/
sum by (namespace, deployment) (kube_deployment_spec_replicas) * 100

Per il timestamp esatto dell’ultimo rollout completato PromQL da solo non basta: meglio correlare con oc rollout status / eventi della pipeline CI.
