Tool to check the result of a templated stack #127
Description
Following my comment in #122 (comment)
It would be nice to have a cli tool that outputs the result of the templating steps without having to spin up a dedicated swarmCD instance.
This would mean extracting the core logic to a separate module that can then be called by both swarmcd and the tool.
The tool can be either a totally separated program executable, or live within a cli command of the current executable (of course using that command would mean to avoid running the current init and run methods).
The inputs should be:
- path of the stack template
- path of the values file
- (if Compose files templating improvements #122 goes through) an optional directory of templates
I would default to stdout for the rendered result.
