Using Docker Compose

Example docker-compose.yml file:

services:
    nginx:
        image: ericmathison/wordpress:latest
        restart: always
        volumes:
            - wp-data:/var/www/html
        environment:
            WORDPRESS_DB_HOST: localhost
            WORDPRESS_DB_USER: db-user
            WORDPRESS_DB_PASSWORD: db-password
