[Feature Request] Ability to build dockerfile located inside sub-directories about habitus

[mumoshu]

@dduportal Hi! Have you tried setting work_dir in your build.yaml like:

build:
  version: 2016-03-14 # version of the build schema.
  steps:
    test:
      name: test
      dockerfile: test/Dockerfile
      work_dir: test/

I suppose it would work as far as I could see from the implementation 😉

Hello @khash @mumoshu , I have opened a first PR with an implementation proposal for this feature: #102

[dduportal]

Hello @mumoshu @khash , thanks for your feedback (and title fix, my aplogizes).

While I am playing with the work_dir option, I would like to contribute to the documentation to add it in the sights of newcomers.

Where could I find the www.habitus.io website documentation content to help?

Thanks for this @mumoshu , but alas, it is not working:

2018/05/10 11:31:00 ▶ Using '/Users/dadou/workspace/habitus/gh-83-workdir/build.yml' as build file 
2018/05/10 11:31:00 ▶ Collecting artifact information

I am reading the source code and trying to get myself ready in Go to contribute.

As I understand the work_dir directive, it is the same thing as the -d option provided byt the habitus CLI, when means "Path to work directory. This is the path where Dockerfiles should exist for each step and the build happens. Defaults to the current directory., so expctation is a flattened file tree. Am I right?

@dduportal thanks for the offer of help with documentation. You can find Habitus.io contents under the gh-pages branch of the repository.
