# MySQL in Docker
docker run --name=mysql01 -p 3306:3306 mysql/mysql-server:latest
docker exec -it mysql01 mysql -uroot -p
# Enter the one time password generated from the docker run command
# and then change the root password
ALTER USER 'root'@'localhost' IDENTIFIED BY 'mypassword';
# Create a user with your host IP address so it can connect from Buffalo
# outside the container
create user 'root'@'172.17.0.1' with password 'mypassword';
GRANT ALL PRIVILEGES ON * . * TO 'root'@'172.17.0.1';

# database.yml looks like this
# Of course, you should be connecting with a different user in a real app.
development:
  dialect: mysql
  database: coke_development
  user: root
  password: mypassword
  host: 127.0.0.1
  pool: 5

Hey there,
Does all of this just go into the database.yml or is the actual docker code supposed to reside elsewhere?

Thanks,
