title: Clarification on Docker Compose's `start_period` paramter
body: <p>I am trying to understand how the <a href="https://docs.docker.com/compose/compose-file/compose-file-v3/#healthcheck" rel="nofollow noreferrer"><code>start_period</code> works with Docker Compose</a>.  If we have the following as a Healthcheck:</p>
  <pre><code>--start-period=60s --retries=2
  </code></pre>
  <p>Does that mean that Docker Swarm will try twice, each time wait 60 sec before considering the container Unhealthy?</p>
  <p>Thank you.</p>
