<p>I have launched cluster using aws eks successfully and applied aws-auth but nodes are not joining to cluster. I checked log message of a node and found this - </p>

<p>I am not sure about this. I have attached eks full access to these instance node roles. </p>

<p>If you are using terraform, or modifying tags and name variables, make sure the cluster name matches <em>in the tags</em>!</p>

<p>Node must be "owned" by a certain cluster. The nodes will only join a cluster they're supposed to. I overlooked this, but there isn't a lot of documentation to go on when using terraform. Make sure variables match. This is the node tag naming parent cluster to join:</p>

<pre><code>  tag {
    key = "kubernetes.io/cluster/${var.eks_cluster_name}-${terraform.workspace}"
    value = "owned"
    propagate_at_launch = true
  }
</code></pre>
