Phoenix Docker Quickstart

A docker compose setup with Phoenix 1.3, Elixir 1.5, Erlang 20.0.

Install Docker: https://www.docker.com/get-docker

Initial setup:

git clone https://github.com/smartmetals/phoenix_quickstart
cd phoenix_quickstart
source functions.sh
phx-new myappname

Note that your app name must start with a letter and have only lowercase letters, numbers and underscore.

Answer yes to the questions about installing dependencies.

Open projects/myappname/config/dev.exs and change the db hostname: from localhost to "db". Do the same in projects/myappname/config/test.exs.

Note below commands use the sourced function dmix, not mix directly.

dmix ecto.create
dserver # docker-compose up

Browse: http://localhost:4000

If you start a new shell, source functions.sh again and run phx-init myappname.

Start a repl with diex. Run any command in the web container with drun.
