I am having a hard time to understand the behaviour of readiness probes and liveness probes. And need some input to rightfully set them:

Here’s my initial configuration:

          readinessProbe:
            httpGet:
              path: /readiness
              port: 4001
            initialDelaySeconds: 300
            periodSeconds: 10
          livenessProbe:
            httpGet:
              path: /liveness
              port: 4001
            initialDelaySeconds: 300
            periodSeconds: 30

Based on my understanding after reading documentation and blogs, as soon as the pod starts up, both readiness and liveness probe will start checking the pod (after waiting for first 300 seconds).

1. Should the initialDelaySeconds of livenessProbe be always greated than that of readinessProbe? Reason being, if liveness checks fails before pod is ready, it will restart it and will get stuck in a loop.

2. What happens when both readiness probe and liveness probe are successful but because of some database downtime, readiness probe starts failing. And the whole webserver is not responding i.e. both endpoints readiness and liveness become unavailable. In this case, I think it will again be stuck in crashing loop, unless the database downtime is over.
