[WIP] Basic Docker Setup

[sigmarstern]

First build the image using docker-compose build. First rm -rf node_modules. (Thanks @pgoetze for pointing that out) Then build the image using docker-compose build. This will:

• Create a new Docker image based on node:argon
• Runs npm install when building the image and keeps installed modules in /tmp/node_modules

Then create and start a new container based on the previously built image using docker-compose up. This will:

• mount application directory to /app inside the container
• create a symbolic link node_modules pointing to /tmp/node_modules if not already present
• create a pre-commit git hook which invokes node_modules/pre-commit/hook inside the container
• run npm run dev
• expose port 8000 (babel) on the Docker machine's port 80
• expose port 8080 (webpack) on the Docker machine's port 8080

@mattberridge, @pgoetze, @artibella could you please give it a try and also check, whether the pre-commit hook is working properly?

Looks like it needs a -d for checking the presence of the directory instead of -h for the shell inside of the container.

docker-compose up with-h fails for me the second time with:

$ docker-compose up
Starting irisfrontend_web_1
Attaching to irisfrontend_web_1
web_1  | Symlink preinstalled node_modules from /tmp
web_1  | ln: failed to create symbolic link '/app/node_modules/node_modules': File exists
irisfrontend_web_1 exited with code 1

Nevermind—I forgot to delete the local node_modules, therefor it failed. Works.
