title: How to use docker with drupal and drush?
body: <p>I'd like to use <a href="https://github.com/drush-ops/drush" rel="noreferrer">drush</a>. It needs to run in the drupal container. There's also a <a href="https://hub.docker.com/r/drush/drush" rel="noreferrer">drush docker repo</a>. But I have no clue how to make it available whithin the drupal container. It's my first docker and drupal project, so maybe I'm getting things completely wrong. </p>
  
  <p>How can I use drush with this drupal docker image?
  <a href="https://hub.docker.com/_/drupal/" rel="noreferrer">https://hub.docker.com/_/drupal/</a>
  Is it possible to manage it with docker-compose? Maybe extending the drupal container?</p>
  
  <p>This is my <code>docker-compose.yml</code>:</p>
  
  <pre><code>mysql:
    image: mysql:5.5
    ports:
      - "3306:3306"
    environment:
      - MYSQL_USER=xxxxx
      - MYSQL_PASSWORD=xxxxxx
      - MYSQL_ROOT_PASSWORD=xxxxxx
      - MYSQL_DATABASE=xxxxxx
  
  drupal:
    image: drupal:8.0.4
    links:
      - mysql
    ports:
      - "8080:80"
  </code></pre>
