title: ecs error: "An error occurred (ClusterNotFoundException) when calling the..."
body: <p>I've defined a cluster in ECS and failed to clean it up properly.  I've  terminated EC2 instances that are associated with this cluster which get recreated.  No clusters/repos/services appear in my ECS console.  In fact, when I go to this service through the console, I see the getting started wizard.  I've started some digging with the CLI.</p>
  
  <p>When issuing the commands:</p>
  
  <ul>
  <li>aws ecs list-container-instances</li>
  <li>aws ecs list-services</li>
  <li>aws ecs list-tasks</li>
  </ul>
  
  <p>I see the message <strong>An error occurred (ClusterNotFoundException) when calling the ____ operation: Cluster not found.</strong> (even when including my region).</p>
  
  <p>When issuing the command:</p>
  
  <ul>
  <li>aws ecs describe-clusters</li>
  </ul>
  
  <p>I get the result:</p>
  
  <pre><code>{
      "clusters": [],
      "failures": [
          {
              "arn": "arn:aws:ecs:us-east-1:123456789012:cluster/default",
              "reason": "MISSING"
          }
      ]
  }
  </code></pre>
  
  <p>Any ideas on how I can clean up my mess would be much appreciated.  Thanks!</p>
