<p>I have a pod running Linux, I have let others use it. Now I need to save the changes made by others. Since sometimes I need to delete/restart the pod, the changes are reverted and new pod get created. So I want to save the pod container as docker image and use that image to create a pod.</p>
<p>I have tried <code>kubectl debug node/pool-89899hhdyhd-bygy -it --image=ubuntu</code> then install docker, dockerd inside but they don't have root permission to perform operations, installed crictl they where listing the containers but they don't have options to save them.</p>
<p>Also created a privileged docker image, created a pod from it, then used the command <code>kubectl exec --stdin --tty app-7ff786bc77-d5dhg -- /bin/sh  </code> then tried to get running container, but it was not listing the containers. Below is the deployment i used to the privileged docker container</p>
<pre><code>kind: Deployment
apiVersion: apps/v1
metadata:
  name: app
  labels:
    app: backend-app
    backend-app: app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: backend-app
      task: app

          hostPath:
            path: /run/docker.sock
            type: Socket
      containers:
        - name: app
          image: registry.digitalocean.com/my_registry/docker_app@sha256:b95016bd9653631277455466b2f60f5dc027f0963633881b5d9b9e2304c57098
          ports:
            - containerPort: 80
          volumeMounts:
            - name: task-pv-storage
              mountPath: /var/run/docker.sock
</code></pre>
<p>Is there any way I can achieve this, get the pod container and save it as a docker image? I am using digitalocean to run my kubernetes apps, I do not ssh access to the node.</p>

<p>This is not a feature of Kubernetes or CRI. Docker does support snapshotting a running container to an image however Kubernetes no longer supports Docker.</p>
