Liveness probes *do not* wait for readiness probes to succeed. If you want to wait before executing a liveness probe you should use initialDelaySeconds or a startupProbe.

Readiness probes are configured similarly to liveness probes. The only difference
is that you use the `readinessProbe` field instead of the `livenessProbe` field.
