# Pod Stuck in Terminating State Due to PreStop Hook.

## Problem

Pod stuck in terminating state, Even the `--force` option in kubectl is failing to delete.

{% tabs %}
{% tab title="Kubelet log" %}

```javascript
Reason:"FailedPreStopHook", Message:"Exec lifecycle hook ([/bin/bash -c service httpd stop; sleep 20]) for Container \"container1\" in Pod \"pod_name3(a8xxx-xxxx-xxx-xxx-xx5e9bb1)\" failed - error: command '/bin/bash -c service httpd stop; sleep 20' exited with 137: , message: \"\\x1b[60G[\\x1b[0;32m  OK  \\x1b[0;39m]\\rForcibly killing nodemanager which has gone rogue. Please check if any of the Applications are still hanging.
```

## Environment

* Platform9 Managed Kubernetes - v5.4 and Higher
* Platform9 Edge Cloud - v5.3 and Higher

## Cause

PreStop hook failure is the reason for the pod to be stuck in termination state, these errors can be seen in the kubelet log.

The **preStop** lifecycle hook in Kubernetes pods allows for performing a specific action before a pod is terminated. It gives applications running in a pod an opportunity to gracefully shut down and clean up any resources or connections before the pod is terminated.

When a pod receives a termination signal, such as when it is being scaled down or during a rolling update, Kubernetes initiates the termination process. Before the pod is actually terminated, Kubernetes executes the **preStop** hook, if defined, in each container of the pod:

The preStop hook within the pod:

{% tabs %}
{% tab title="Pod manifest" %}

```javascript
# kubectl get pod pod_name3 -n ns1 -oyaml
apiVersion: v1
kind: Pod
metadata:
  name: pod_name3
  namespace: ns1
spec:
  containers:  
    preStop:                                                              
        exec:
          command:
          - /bin/bash
          - -c
          - service stop httpd; sleep 20
```

{% endtab %}
{% endtabs %}

## Solution

Possible solutions to stop pod being stuck in termination is to identify the reason why the preStop hook commands are failing, and fixing the issue associated with these commands should resolve the issue.

From the above example: Investigate why the `httpd` service is failing to stop within the `container1` of the pod `pod_name3.`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/pmk/solutions/pod-stuck-in-terminating-state-unless-deleted-forcefully.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
