In such cases, it can be tricky to set up liveness probe parameters without compromising the fast response to deadlocks that motivated such a probe. The solution is to set up a startup probe with the same command, HTTP or TCP check, with a failureThreshold periodSeconds long enough to cover the worst case startup time.\n\nSo, the previous example would become\n\nBounded code example (external data; do not execute automatically):\n```yaml\nports:\n- name: liveness-port\n  containerPort: 8080\n\nlivenessProbe:\n  httpGet:\n    path: /healthz\n    port: liveness-port\n  failureThreshold: 1\n  periodSeconds: 10\n\nstartupProbe:\n  httpGet:\n    path: /healthz\n    port: liveness-port\n  failureThreshold: 30\n  periodSeconds: 10\n```\n\nThanks to the startup probe, the application will have a maximum of 5 minutes (30 10 = 300s) to finish its startup. Once the startup probe has succeeded once, the liveness probe takes over to provide a fast response to container deadlocks. If the startup probe never succeeds, the container is killed after 300s and subject to the pod's restartPolicy.\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
