title: How to install php-mcrypt in lando with php 7.2?
body: <p>Following example in <a href="https://stackoverflow.com/questions/47181369/how-to-install-mcrypt-on-docker/53466129#53466129">How to install mcrypt on Docker</a> I came to this: </p>
  
  <pre><code>name: myapp
    recipe: drupal7
    config:
      webroot: web
      php: '7.2'
  proxy:
    pma:
      - pma.myapp.lndo.site
  services:
    pma:
      type: phpmyadmin
  appserver:
    extras:
      - "apt-get update -y"
      - "apt-get install libmcrypt-dev"
      - "pecl install mcrypt-1.0.1"
      - "docker-php-ext-enable mcrypt"
  </code></pre>
  
  <p>After rebuilding I see: </p>
  
  <pre><code>$ lando php -m | grep mcrypt
  mcrypt
  </code></pre>
  
  <p>But in my web application when I look at the page with phpinfo(), then there is no trace of mcrypt. Please help me out to install php-mcrypt correctly. </p>
