How to Fix Kubernetes Pods Stuck in Terminating Status

How to Fix Kubernetes Pods Stuck in Terminating Status

Kubernetes is a popular container orchestration tool used to automate the deployment, scaling, and management of containerized applications. However, sometimes pods can get stuck in terminating status, preventing new pods from being scheduled on the same node. This can be frustrating, but luckily there are several ways to fix this issue.

In this article, we will discuss the steps you can take to resolve the problem of Kubernetes pods stuck in terminating status.

  1. Identify the Pod

The first step in fixing the issue of Kubernetes pods stuck in terminating status is to identify the pod causing the problem. You can do this by running the following command:
kubectl get pods --all-namespaces | grep Terminating

This command will show you a list of all pods that are in the terminating state.

  1. Check the Pod Status

After identifying the pod causing the problem, you need to check its status to see why it's stuck in the terminating state. You can do this by running the following command:
kubectl describe pod <pod-name> -n <namespace>

This command will give you a detailed description of the pod, including its current status and any events that have occurred.

  1. Delete the Finalizer

If a pod is stuck in the terminating state, it's likely because it has a finalizer that is preventing it from being deleted. To delete the finalizer, you can run the following command:
kubectl patch pod <pod-name> -n <namespace> -p '{"metadata":{"finalizers":[]}}' --type=merge

This command will remove all finalizers from the pod, allowing it to be deleted.

  1. Force Delete the Pod

If the previous steps did not work, you can force delete the pod by running the following command:
kubectl delete pod <pod-name> -n <namespace> --grace-period=0 --force

This command will forcefully delete the pod, ignoring the grace period.

  1. Check Node Status

If the pod is still stuck in the terminating state after force deleting it, you should check the status of the node it was running on. You can do this by running the following command:
kubectl describe node <node-name>

This command will give you a detailed description of the node, including its status and any events that have occurred.

  1. Restart Kubernetes Services

If the node is healthy and the pod is still stuck in the terminating state, you should try restarting the Kubernetes services on the affected node. You can do this by running the following command:
systemctl restart kubelet.service

This command will restart the kubelet service, which is responsible for managing pods on the node.

By following these steps, you should be able to fix the issue of Kubernetes pods stuck in terminating status. If none of these steps work, you may need to contact Kubernetes support for further assistance.
