title: docker-compose phpmyadmin kicks out
body: <p>I'm trying to use a docker-compose.yml for launching <code>mariabd</code> and <code>phpmyadmin</code>. When I edit something on <code>phpmyadmin</code> it kicks me out to login page.</p>
  
  <pre><code>db:
    image: mariadb
    environment:
      MYSQL_ROOT_PASSWORD: Pass123
    restart: always
    volumes:
      - "./.data/db:/var/lib/mysql/:rw"
  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    links:
      - db:mysql
    ports:
      - 8181:80
    environment:
      MYSQL_USERNAME: root
      MYSQL_ROOT_PASSWORD: Pass123
      PMA_HOST: mysql
  </code></pre>
  
  <p>I've tried with a volume container with <code>busybox</code> to keep data of <code>mysql</code>, changed <code>mariabd</code> for <code>mysql</code> image. But I don't get with the solution. What should I do to solve this?</p>
  
  <p>Thanks in advance</p>
