Can I add side car container to a running pod?

[Tamal Saha]

Hi,

I am working on a TPR controller that will add a side card container to a pod. From what I can tell so far is that a side car container can't be added to an existing pod. I get an error message like below:

1. pods "two-containers" was not valid:

2. # * spec.containers: Forbidden: pod updates may not add or remove containers

3. #

So, my TPR controller basically have to add the side card container to the RC or Deployment PodTemplate and then restart the pods. Is there a way to do with without requiring restarting running pods? This seems possible from pure Linux namespace perspective.

Thanks,

Afaik, is not possible.

And the idea is that deploys are easy, so you do them a lot, and not mutate your things but just deploy (to add a sidecar container or whatever).

But maybe there is a way that I don't know about
