How to delete CrashLoopBackOff pod

Dealing with Kubernetes pods in the “CrashLoopBackOff” state is often a headache for many of our customers.

According to our experts, this state lets us know that a pod has been repeatedly crashing, and to prevent further resource drain, Kubernetes intervenes and puts a stop to its restart attempts.

Today, we are going to take a look at identifying, understanding, and resolving this issue.

1. First, we have to identify the pod behind the fuss. So, open a command line and run this command:

   kubectl get pods

   This gives a list of all pods in our Kubernetes cluster and their respective statuses. We have to look through the list to spot the pod marked with the “CrashLoopBackOff” status.
2. Next, we have to run this command with the pod name with the CrashLoopBackOff status:

   kubectl describe pod pod_name

   This will give us a breakdown of the pod, including a timeline of events leading up to the crashes.
3. Now, it is time to delete the pod causing the issues with this command:

   kubectl delete pod pod_name

   By running this command Kubernetes will terminate the problematic pod. Furthermore, if the pod is part of a deployment or replica set, Kubernetes will create a replacement automatically.
4. At this point, we have to monitor the new pod to ensure it does not follow the same crash-prone path. We can use this command to check the status of the pod:

   kubectl get pods
5. If the problem continues, we have to find the root cause behind the crashes. Looking through the logs will help us with this. We can access the logs with this command:

   kubectl logs pod_name
