title: Amazon ECS "the referenced cluster was inactive"
body: <p>I followed the steps to install the ECS client on Ubuntu 16, but when I try to run the ECS container agent, it keeps restarting and when I have a look at the logs</p>

  <p>I didn't find a reference for this error on google and I'm wondering what's wrong...</p>
  
  <p>Do I need to create the cluster name on the ECS dashboard ?
  I have attacher the container role to my EC2 instance, which allows for cluster creation so I don't think the problem comes from here...</p>
