Allow template rendering from the command line

[maxlaverse]

Hey!
Would it be acceptable to have a feature to only render templates and not applying them ? Similar to what can be done with Helm ?

This allows parsing the generated template to extract some information for other tools, like all the images involved.

Hi! I think this is a great idea, and it fits in nicely with some thoughts I was having about the future of rendering in this tool (#44 (comment)). Can you make it a completely separate command though? Maybe kubernetes-render? That would also require extracting a renderer class that could be called from both the new executable and DeployTask, which I think makes a lot of sense, especially as the renderer gets more complex. IMO the class extraction is also required for #207, so please coordinate with @skaes (who isn't at Shopify either--it's great to have all these contributions! ❤️ ) about who will have time to do that piece first.

Sure @KnVerey , I'll talk to him

Hi @KnVerey.
I rebased the PR and introduced a new command as suggest.
Could you point me in the direction you want this feature to go ?

I won't really have time to work on this pull-request anymore.
I prefer to close it and re-open it in the future if I want to invest in that direction again.
