Umbrella App mix docker.build failed

[kloktech-mark]

Following error displayed when running mix docker.build. I am not sure if this is related to #15 where app and version needs to specified, the referenced distillery's issue, bitwalker/distillery#201

@linmark333 Please try current master (f5c504f)

/cc @lpil this might also solve your umbrella issues

@teamon I've also run into this problem in my umbrella app, and have retried using master. I get the same error from master.

Output:

The command '/bin/sh -c mix release --env=prod --verbose' returned a non-zero code: 1

Edit

To provide a bit more information, above that error and stack trace, I get some other errors:

Step 12/12 : RUN mix release --env=prod --verbose
 ---> Running in fac10e2b1e53
fatal: Not a git repository (or any of the parent directories): .git

That Not a git repository error repeats a number of times. Finally, some dependency errors which is really weird to me…

Unchecked dependencies for environment prod:
* amqp (Hex package)
  the dependency is not available, run "mix deps.get"

It lists all my app's dependencies there, not just a couple.

These errors only happen when running a mix docker.build

It's because in the Dockerfile.build, the mix.exs and mix.lock is copied, but I believe this won't work for an umbrella app, as this will require apps etc as well?

[jeremytregunna]

I manually copy all the apps as well. I don't recall how I worked around this issue, but I since have. Not helpful I know, so my apologies about that.

EDIT: To clarify, I copy the mix.exs's from the apps, and their respective configs.

@jeremytregunna yeah, did the same and works. Testing now, this is awesome :)
