Support for deploying just a single module

[jovrum]

r10k supports deploying a single module to a specific environment like so:

r10k deploy module foobar -e production

This deploys module foobar to environment production but leaves other modules untouched.

This is useful when pinning a lot of modules to the latest version or head of a git branch and only doing full environment deploys on a regular basis. It would be really nice if g10k supported the same workflow.

To be honest I could not get it to work with r10k.

Could you please provide a complete command including a r10k config (like https://github.com/xorpaul/g10k/blob/master/test.yaml) that does what you want?

[jovrum]

Sure, here's a control repository, r10k configuration file and a readme describing how to reproduce:

https://github.com/jovrum/r10k-single-module-env

One thing I noticed is that the $basedir/production directory has to exist when doing a single-module deployment in the production environment, otherwise r10k will exit almost immediately with status 0 and no output. r10k deploy environment ... creates the necessary directory structure. This has not been a problem for me in practice, but I can't see how this would be intended or useful behavior.

Fixed with https://github.com/xorpaul/g10k/releases/tag/v0.3.12

Awesome, thanks! Will test it out later.
