Foodsoft on Docker
This document explains setup and using docker the foodsoft with docker.
Requirements
- Docker (=> 1.5)
- Docker Compose (=> 1.1)
- 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
TODO: Right know this is not gonna work because of the new database configuration via ENV variable. See Notes below.
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
Run the tests
docker-compose run app ./bin/test
Jump in a running container for debugging.
docker exec -ti foodsoft_app_1 bash
Notes
Gemfile updates
This is bit tricky, as the gemfiles are stored in the container and so we have to rebuild the container each time we change the Gemfile. To avoid installing all the gems from scratch we can use this workaround:
docker-compose run app bundle update rails # Update Gemfile.lock file
docker ps -a # Look for the last exited container and grab the Container ID
docker commit -m "Updated rails" <Container ID> foodsoft_app
Database configuration
TO make thins easier we use the ENV Variable DATABASE_URL. But to make this work, the shouldn't be any config/database.yml file!
