Liveness probe is not configured

Description

The kubelet uses liveness probes to know when to schedule restarts for containers. Restarting a container in a deadlock state can help to make the application more available, despite bugs.

If a container is unresponsive, either to a deadlocked application or a multi-threading defect, restarting the container can make the application more available, despite the defect.
