<p>I need a help with EKS managed node group.
I've created a cluster with one additional sg. Inside of this cluster I've created managed node group. All code is stocked in terraform. Once managed node group creates new instance, only one security group is attached (SG created by AWS). Is it somehow a way to attach also additional security group to instances?</p>
<p>Thanks in advance for help!</p>

<p>If you are using terraform stock module, you can only add the additional security group in your terraform code and re-apply. Using the EKS console is <a href="https://github.com/aws/containers-roadmap/issues/1588" rel="nofollow noreferrer">work-in progress</a> (you can help to upvote).</p>
