If anybody uses this in prod from a git repo, might want to place your database creds in an .env file adjacent to your compose file then gitignore the .env.

Referenced like so:

.env contents

MYSQL_ROOT_PASSWORD=MyExamplePassword

MYSQL_ROOT_USER=MyExampleUser

docker-compose.yml contents:

MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}

MYSQL_ROOT_USER: ${MYSQL_ROOT_USER}

Don’t commit secrets to git!

Damn mobile formatting.
