Added the Docker SBT plugin.

Whoever reviews this, please confirm that you can get the server running on Docker before merging.

It works for me, but it would be great to confirm that I didn't forget to commit set-up files or something.

Part of feature CSSE497/pathfinder#8.

Why are ports 9000 - 9443 open?

[aj-michael]

It's not 9000 - 9443. It's 9000 and 9443. The default Play HTTP port is 9000. The default Play HTTPS port is 9443.

What is the output of the following commands?

docker-machine -v
docker -v
activator --version

[aj-michael]

It looks like this may be a problem with an older version of SBT that they fixed:

http://stackoverflow.com/questions/30565463/java-util-regex-patternsyntaxexception-when-using-sbt-dockerpublishlocal

sbt/sbt-native-packager#588

It is working for me with sbt launcher version 0.13.8

[grovecj]

docker-machine.exe version 0.4.1 (e2c88d6)
Docker version 1.8.2, build 0a8c2e3
sbt launcher version 0.13.8

[aj-michael]

Hmmm, I have the same versions except that I have Docker 1.8.1 instead of Docker 1.8.2. Will investiage.

[grovecj]

Are you testing this on linux?

[aj-michael]

I have only tested it on OSX, trying Windows now.

[aj-michael]

Ok, I can reproduce this error on Windows with the same versions as OSX. My hunch is it's a backslash-in-file-path regex problem in the docker stack somewhere.

[aj-michael]

Ok, I've found a solution and have now successfully run the project on Docker on Windows.

I added a commit to update the Sbt Native Packager.

There were also a few additional steps:

1. I restarted the container with docker-machine restart default.
2. I set the configuration in my cmd prompt with docker-machine env default --shell=cmd and then running the commands that it tells you to run.
