Foodsoft on Docker

This document explains setting up and using Foodsoft with Docker.

Requirements

Docker (=> 1.9.1)
Docker Compose (=> 1.4)
Nothing more, no ruby, mysql, redis etc!

For installing instructions see https://docs.docker.com/installation/. Docker runs on every modern linux kernel, but also with a little help on MacOS and Windows!

Setup

Create docker volume for mysql data:

mkdir -p ~/.docker-volumes/foodsoft/mysql

Setup foodsoft development data: (This will take some time, containers needs to be pulled from docker registry and a lot dependencies needs to be installed.)

docker-compose run app rake foodsoft:setup_development

Usage

Start containers (in foreground, stop them with CTRL-C)

docker-compose up

Run a rails/rake command

docker-compose run app rake db:migrate

Open a rails console

docker-compose run app rails c

Setup the test database

docker-compose run app rake db:setup RAILS_ENV=test DATABASE_URL=mysql2://root:secret@mysql/test

Run the tests

docker-compose run app ./bin/test

Jump in a running container for debugging.

docker exec -ti foodsoft_app_1 bash

Receiving mails

Go to http://localhost:1080.

Notes

Gemfile updates

As we use a special container (bundle, see docker-compose.yml) you only have to run the bundle command as normally: docker-compose run app bundle

Database configuration

To make this easier we use the environment variable DATABASE_URL (and TEST_DATABASE_URL when using the testing script).
