title: How chain sleep command in docker compose?
body: <p>Consider a snippet:</p>
  
  <pre><code>---
  version: '3.4'
  services:
    app:
      image: my_image
      command: ["sleep", "60s", "&amp;&amp;", "my_command"]
  </code></pre>
  
  <p>Gives me:</p>
  
  <pre><code>sleep: invalid time interval вЂ�my_commandвЂ™
  Try 'sleep --help' for more information.
  </code></pre>
  
  <p>What is wrong? Why did this happen?</p>
  
  <pre><code>Docker version 19.03.2, build 6a30dfc
  Host OS - windows 10
  </code></pre>
