Support converting OpenShift json <-> Kubernetes json/yaml

[rothgar]

As a user I'd like to use OpenShift json files or Kubernetes yaml files to convert manifests from one environment to the other. This seems like it would be easier to support than docker-compose files but currently is a manual process (as far as I've found).

Maybe I missed an existing issue or PR (I searched) but this would be a great addition for both communities.

just to confirm, instead of transforming from docker formats to k8s/openshift, you would like to transform from openshift to k8s ?

[rothgar]

Correct. That is my initial goal, but I could also see a use case to switch from k8s manifests -> openshift

Hi,
regarding k8s->openshift you don't need any conversion, everything that works on k8s should work on OpenShift by default.

Other way is problematic. OpenShift is superset of k8s. For most objects it will be ok (because they are same in openshift and k8s), but there are objects in OpenShift that cannot be easily mapped to Kubernetes, for example BuildConfig.

Theoretically it can be done (to some degree), but I don't think that it is something that is in scope for Kompose.

[rothgar]

If it's out of scope that is fine (we can close this issue) I just think it may be a use case for some people. Me being one of those people where I often translate OpenShift -> Kubernetes manifests manually. It could help broaden available applications for both OpenShift and vanilla Kubernetes

@rothgar this has come up a few times in OpenShift as well. Even if we don't want to do it here, I'd be open to implementing it in the OpenShift CLI or another command. I agree the idea of:

deployment config -> deployment
route -> ingress

and vice versa would be very useful.

[rothgar]

I assumed kompose would be the tool to do the conversions. It'd be nice if I didn't need oc or multiple conversion tools for each scenario.

[sebgoa]

@rothgar let's definitely keep this issue open. We talked about supporting other input formats (like nomad Jobs) for example, so we could add openshift -> k8s conversion.

And I agree that having only one conversion tool would be better.

@fejta-bot @fejta How do I remove / whitelist the Kompose repo from this bot?

[fejta]

Move it out of the kubernetes org

[kadel]

@cdrage I think that this bot will be useful

[cdrage]

@fejta Okay, we'll keep it around 👍

Since there's been no activity since December and this has (mainly) been used as a Docker Compose to Kubernetes / OpenShift tool, I'm going to close this (for now).
