1. Create the Dockerfile for postgres service

cd apps/web/ python3 create_postgres_dockerfile.py cd ..

2. Build and run the Docker containers

time docker-machine create -d virtualbox dev; eval "$(docker-machine env dev)"

time docker-compose build time docker-compose up -d time docker-compose run web env time docker-compose logs

How to cache locally? ??

3. Create or re-initialize the database

docker-compose run --rm web python ./instance/db_create.py

$ psql -p 5432 -U postgres --password

POSTGRES_USER = 'teladoc'

POSTGRES_PASSWORD = 'flask_recipes'

Set environment variables

ENV POSTGRES_DB workflow_recipes

Go to your favorite web browser and open:

http://192.168.99.100:5000  $ Check the IP address using 'docker-machine ip'

Stop and remove all docker containers.

docker ps -aq. docker stop $(docker ps -aq) docker rm $(docker ps -aq)

Remove docker-machine named dev

docker-machine rm dev
