<p>I have a running multi-container kubernetes pod and I want to add another docker container to this running pod instead of deleting and creating the pod from scratch.</p>

<p>When you make changes to your pod and deploy them, the replication controller will delete the pod and recreate it with the new configuration - that's how Kubernetes works.</p>

<p>If you're worried about downtime, you can set your Replicas to 5 for example, and enable Rolling Update. This way the pods will be restarted one by one.</p>
