Featuring:

• Docker Compose v1.12.0
• Python 3.6 (With an virtul environment)

OS X Instructions

1. Start new machine - docker-machine create -d virtualbox dev;
2. Build images - docker-compose build
3. Start services - docker-compose up -d
4. Create migrations - docker-compose run web /usr/local/bin/python manage.py migrate todo
5. Grab IP - docker-machine ip dev - and view in your browser

Ubuntu Instructions

1. Start a python virtul environment, pip install docker-compose
2. Point docker to VM (you may need to start the vm docker-machine start dev), eval $(docker-machine env dev)
3. build images - docker-compose build
4. Start services -docker-compose up -d
5. Create Database in postgres -psql -h 192.168.x.x -p 5432 -U postgres create database my_db \l check List of databases.
6. Create migrations -docker-compose run web python manage.py migrate

Note

requirements.txt is update. docker-compose.yml is update. production.yml is not update. If you have old pgdata volume, remember delete it, or your will get errors.

postgres_1  | FATAL:  database files are incompatible with server
postgres_1  | DETAIL:  The data directory was initialized by PostgreSQL version 9.5, which is not compatible with this version 9.6.2.

docker-compose down won't delete volumes! You should do it by manual. docker-compose.yml 中的volume的路徑要用絕對路徑。 postgresql 要另建my_db
