title: ECS_CONTAINER_METADATA_URI_v4 Not available
body: <p>I have an ECS cluster which has a few services.
  All the containers are running on EC2 mode.</p>
  <p><strong>Objective</strong>: I want to get the service name inside the container.</p>
  <p><strong>Steps taken</strong></p>
  <ol>
  <li>Enabled &quot;enable_ecs_managed_tags: true&quot;</li>
  <li>RAN <code>wget -qO- $ECS_CONTAINER_METADATA_URI/taskWithTags</code>
  --&gt;this does not give me the <code>aws:ecs:serviceName</code> which I need.</li>
  <li>So I ran <code>wget -qO- $ECS_CONTAINER_METADATA_URI_V4/taskWithTags</code>
  --&gt;this doesn't return anything at all.</li>
  </ol>
  <p>What am I doing wrong? Or is there another way to get the service name to which the container belong to.</p>
  <p>BTW I've double checked if the tags are there. They are there as required in the tasks which can be seen from the AWS console.</p>
