How To Run

---

Build for Local

1. create docker-machine for local (with virtualbox driver)

$ docker-machine create --driver virtualbox dev

2. activate docker-machine

$ eval $(docker-machine env dev)

3. add environment

$ export REACT_APP_USERS_SERVICE_URL=http://DOCKER_MACHINE_IP

4. Build the images and spin up the containers

$ docker-compose up -d --build

5. create and seed the db then run the tests

$ docker-compose run users-service python manage.py recreate_db
$ docker-compose run users-service python manage.py seed_db
$ docker-compose run users-service python manage.py test

Test it by opening your browser http://0.0.0.0:80 or http://0.0.0.0:80/users

---

Build for Production

1. create docker-machine for production (with driver digitalocean based on ubuntu 14.04)

$ docker-machine create --driver digitalocean --digitalocean-access-token=DO_TOKEN --digitalocean-image ubuntu-14-04-x64 prod

2. activate docker-machine

$ eval "$(docker-machine env prod)"

3. add environment

$ export REACT_APP_USERS_SERVICE_URL=http://DOCKER_MACHINE_IP
$ export SECRET_KEY=MyS3cr3tK3y

4. Build the images and spin up the containers

$ docker-compose -f docker-compose-prod.yml up -d --build

5. create and seed the db then run the tests

$ docker-compose -f docker-compose-prod.yml run users-service python manage.py recreate_db
$ docker-compose -f docker-compose-prod.yml run users-service python manage.py seed_db
$ docker-compose -f docker-compose-prod.yml run users-service python manage.py test

6. watch the logs

$ docker-compose logs -f users-service

7. grab ip

$ docker-machine ip prod

Test it by opening your browser http://YOUR_PROD_IP:80 or http://YOUR_PROD_IP:80/users
