title: Docker compose up [ecs context] with private repo
body: <p>Trying to upload compose.yml to aws with docker-compose [ecs context];
  Have my private repositories in <a href="https://hub.docker.com/" rel="nofollow noreferrer">https://hub.docker.com/</a>.</p>
  <ol>
  <li>Created ecs context, started to use it (docker context use)</li>
  <li>Executed <code>docker login</code> -&gt; login succeeded</li>
  <li>Executed <code>docker compose up</code></li>
  </ol>
  <p>It fails and returns the error</p>
  <blockquote>
  <p>ServerService TaskFailedToStart: CannotPullContainerError: inspect image has been retried 1 time(s): failed to resolve ref &quot;docker.io/myrepo/server:latest&quot;: pull access denied, the repository does not exist or may require authorization: server message: insufficient_scope: authorization...'</p>
  </blockquote>
  <p>How should I get access to this 'docker ecs compose' tool? Is it related somehow to aws credentials?</p>
