Subir WordPress PHP + MYSQL com Docker Compose

Vamos criar um novo diretório para criar o dockerCompose e arquivos do WordPress.
No site do docker hub temos um exemplo de uso para criação de imagem wordpress
https://hub.docker.com/_/wordpress

version: '3.1'

services:

  wordpress:
    image: wordpress
    restart: always
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: exampleuser
      WORDPRESS_DB_PASSWORD: examplepass
      WORDPRESS_DB_NAME: exampledb
    volumes:
      - wordpress:/var/www/html

  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_DATABASE: exampledb
      MYSQL_USER: exampleuser
      MYSQL_PASSWORD: examplepass
      MYSQL_RANDOM_ROOT_PASSWORD: '1'
    volumes:
      - db:/var/lib/mysql

volumes:
  wordpress:
  db:

Apenas executamos o comando para dar build no docker-compose e após subir os containers.

docker-compose build
docker-compose up
