What to do if POD is not working?

Look at the bottom of your pod to make sure it still has the silicon grommet. If no, the air channel will not seal so the device will not work. Next you want to clean both of the contact pins on the inside of your device. Pocket lint, dirt, juice and other materials can prevent a proper connection. If Pod’s status is Failed , Kubernetes will try to create new Pods until it reaches terminated-pod-gc-threshold in kube-controller-manager . This will leave many Failed Pods in a cluster and need to be cleaned up. A pod is the smallest unit in Kubernetes (K8S). They should run until they are replaced by a new deployment. Because of this, there is no way to restart a pod, instead, it should be replaced. A pod is the smallest unit in Kubernetes (K8S). They should run until they are replaced by a new deployment.

What happens when a pod fails?

If Pod’s status is Failed , Kubernetes will try to create new Pods until it reaches terminated-pod-gc-threshold in kube-controller-manager . This will leave many Failed Pods in a cluster and need to be cleaned up. To restart without any outage and downtime, use the kubectl rollout restart command, which restarts the Pods one by one without impacting the deployment. Notice in the image below Kubernetes creates a new Pod before Terminating each of the previous ones as soon as the new Pod gets to Running status. In general, Pods do not disappear until someone destroys them. This might be a human or a controller. The only exception to this rule is that Pods with a phase of Succeeded or Failed for more than some duration (determined by the master) will expire and be automatically destroyed. Without a service, Pods are assigned an IP address which allows access from within the cluster. Other pods within the cluster can hit that IP address and communication happens as normal.
