docker: mysql: docker-compose.yml setup

If you need a quick mysql that stuff can connect to -create a new folder and inside it create a file named docker-compose.yml and put the following in it.  If you need to install docker/docker-compose a quick script is here:

Note: version '2.0' is now obsoleted.

version: '2.1'

services:
  mysql:
    image: mysql:8.0
    restart: always
    ports:
      - 3306:3306
    volumes:
      - ./mysql:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: 'somepassword'

To check that it ran properly:

docker-compose up

To run permanently in daemon mode:

docker-compose up -d
