Elixir & Phoenix development using Docker.

For setting up a docker development environment for Elixir & Phoenix.

1. Set PHOENIX_DOCKER_GENERATOR to the path of this folder, for example if it's at $HOME/repos/phx-docker-gen, then put this in your .{z,bash}rc file: export PHOENIX_DOCKER_GENERATOR=$HOME/repos/phx-docker
2. Then stick the file gen-phx in your path.
3. Run gen-phx appname; appname should be underscore-case format. The script changes "hostname" from "localhost" to "db" in config/dev.exs; it needs to match the database service named in docker-compose.yml, in this case it is db.

For an existing project, follow steps 1 and 2 above and run gen-phx-existing inside the project folder. It will add the 3 Docker files (or overwrite them if they exist, adjust the script per your needs), set up the containers and run migrations.
