# 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
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!
