Can you give some more details about what you re trying to accomplish

clean-engineer-75963 · Answer

I have a fiddly deploy step where I need to create a Deployment then port forward into one of the Pods it creates to finish configuring the software

gorgeous-egg-16927 · Answer

What are you using to do the port forwarding kubectl

clean-engineer-75963 · Answer

Yes since the Python kubernetes client doesn t support it yet

gorgeous-egg-16927 · Answer

Ok then I d suggest using the selector to find the Pod s rather than using the name directly

clean-engineer-75963 · Answer

`kubectl port forward` doesn t support ` l`

gorgeous-egg-16927 · Answer

You can do something like ```kubectl get pods selector=app=cassandra``` to list all matching pods and could further filter that down as needed

Yes definitely an option I was wondering if there was a Pulumi native way to do it

gorgeous-egg-16927 · Answer

Well if you figure out the correct kubectl incantation you should be able to shell out to it from within a pulumi program and then use that output

gorgeous-egg-16927 · Answer

Or use a k8s client for python

gorgeous-egg-16927 · Answer

That scenario is currently a bit outside of our main workflow but feel free to open an issue on <https github com pulumi pulumi kubernetes issues> if you want to provide more details on your use case

gorgeous-egg-16927 · Answer

`kubectl get pods selector=tier=frontend o jsonpath= items 0 metadata name ` will get you just the pod name
