title: Terraform AWS EKS security group issue
body: <p>I am deploying AWS EKS Cluster using a terraform script. Everything is deploying fine. 
  But I am stuck in an issue with the security group. I have added two ports to allow ingress traffic to my application URL. </p>
  
  <p>But the issue is that, after complete deployment of EKS cluster there is two security group created, one which I have created and other is created by EKS itself. </p>
  
  <p>So here I have to manually add the port in EKS created security group to access my application's URL on the browser. </p>
  
  <p>Here how I can add my specific ports in EKS created security group.</p>
