allow additional overrides

[sgarlick987]

Hi, I had a use case around overriding some additional config when duplicating pods.

The background is that we currently use kubectl debug --copy-from for creating rails consoles for engineers to debug with instead of asking them to exec into running pods which may cause disruption if they use more resources than allocated. Our setup specifically has a deployment of one replica that is running a idle rails console, which engineers then copy from when wanting to get into a console and debug. This has a few problems.

1. Since deployments don't support restartPolicy Never when the engineer exits their debug pod it restarts and continues to run after they've finished.
2. Since the pod they clone from is idle, we want to keep its resource usage set as low as possible, but currently it has to be set to a reasonable amount of memory for them to work with

Would being able to override good additions to duplik8s? Thanks.

Hi @sgarlick987, thanks for the feedback! Good idea, being able to override the spec of the duplicate Pod does sound useful. I’ll take a look into it!
