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).
