title: AWS creation failed: Service already exists. (Service: AWSServiceDiscovery; Status Code: 400; Error Code: ServiceAlreadyExists; Request ID)
body: <p>I am new to AWS and encountered some problem while trying to create a EC2 service in a ECS cluster.</p>
  <p>I was able to successfully create a brand new service (<code>service1</code>) in <code>cluster1</code>, but afterwards, I decided to delete <code>cluster1</code> and create <code>cluster2</code>. The problem came when I try to re-create <code>service1</code> in <code>cluster2</code>. Whenever I try to add the service, I will get the following error</p>
  <pre><code>creation failed: Service already exists. (Service: AWSServiceDiscovery; Status Code: 400; Error Code: ServiceAlreadyExists; Request ID: d854025e-ebcc-11e8-84ab-b3bac906f2ef)
  </code></pre>
  <p>Does anyone know how to resolve this problem? I have tried deregistering the task definition but it didn't work. <code>cluster1</code> has been deleted and there are no services in <code>cluster2</code>.</p>
