Idea: kompose up, ps, delete, scale redirect to kubectl

[janetkuo]

kompose up, ps, delete, scale are duplicate of kubectl, but are easier to learn from compose users perspective.

How about we suggest users the right kubectl command for each kompose command so that we don't need to reinvent the wheel? Something like:

$ kompose up
To initiate your compose services, run "kubectl create -f web-rc.json -f web-svc.json".

Thoughts?

I like it but maybe we shouldn't make it so manual by making them copy/paste. Maybe something like:

$ kompose up
To initiate your compose services, run "kubectl create -f web-rc.json -f web-svc.json".
Would you like us to run that command for you now? (y/n)

Ah ha, that makes more sense to me @dustymabe

[janetkuo]

@dustymabe Thanks that sounds good!

yes +1
we can support up, ps and delete via a simple wrapper to kubectl
and focus on the conversion for now.

Open question: what's the right behavior of kompose up?

1. If there's no existing converted k8s files: it should tell the users to run kompose convert
2. If there's multiple existing k8s files: should it just create whatever config files we have? What if those files are stale (docker-compose.yaml updated since last conversion)? What if we have more than one k8s files (.yaml, .json, different controllers...)? We can just convert again and then create those k8s primitives, but we don't have the options in kompose up like we do in kompose convert.

Open question: what's the right behavior of kompose up?

Update per earlier discussion with @Runseb and @ngtuna: kompose up will do the equivalent of kompose convert && kubectl create -f <svc_files> -f <deployment_files> ... (note that we only support default convert behavior, i.e. converting to deployments)

Close as dup #40 #41

@ngtuna what about kompose ps and kompose scale?

[ngtuna]

@janetkuo By closing this issue, I just wanna make some clean up on issues. We can have another discussion on kompose ps and kompose scale, then we open the corresponding issues for them later.
