To understand the concept of graceful shutdown, let’s quickly review how Kubernetes shuts down containers. When a user or the Kubernetes scheduler requests deletion of a pod, the kubelet running on a node first sends aSIGTERMsignal via the Linux operating system. The container can register a ...
While the pod is running, the kubelet can restart each container to handle certain errors. Within the pod, Kubernetes tracks the state of the various containers and determines the actions required to return the pod to a healthy state. A pod cannot repair itself—if the node where the pod is...

(by default) orOnfailure. The kubelet reads this configuration and tries to restart it, eventually ending in a loop. This wait time lets us know that there is a problem within the program and gets us to check on them. So, CrashLoopBackOff is not entirely bad. It works like a warning...
