We might want to look into expanding play kube to other YAML in the future, so it might be worth keeping the issue open as an enhancement

[haircommander]

I think rescoping the issue as an enhancement would be best. We could create a list of possible yaml kinds we could support. As of now, it reads like a bug
Edit: I am wrong, it does read like an enhancement, but I think having our own issue to track ones we want to support in one place would be good

LGTM and all happy green test buttons.

@haircommander -- I agree. I think that Podman in a future release should support the Kubernetes deployment spec as well as the pod spec. I think a good stop gap is throwing the error message you have in this PR, but the vast majority of Kubernetes deployments (at least that I've seen) all use the deployment spec.

/lgtm
I'll reopen #4093 once this closes it, and retag as enhancement

[rhatdan]

@haircommander Would you like to look into supporting the Deployment spec?

[haircommander]

@rhatdan sure, as time allows 😄
