[EKS][request]: Add support for tagging ENIs provisioned for worker nodes

[kishoreakshat]

Tell us about your request

We would like to have support for propagation of custom tags to ENIs being used by worker nodes.

Which service(s) is this request for?
EKS

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?

Currently, if you add Resource Tags for Network Interfaces in a Launch Template and use this Launch Template to create/update a Managed Nodegroup, the new Launch Template created by created by EKS workflow does not copy these ENI resource tags and hence any custom tags are not propagated to the underlying ENIs.

Are you currently working around this issue?

There is no workaround currently. The only brute approach is to tag ENIs manually but that hardly helps in automating the process as nodes may get recycled and ENIs ay be detached and reattached.

We have already tried:

1. aws autoscaling create-or-update-tags CLI command [1].

2. using eksctl to apply tags

eksctl create nodegroup --managed --tags --cluster <cluster_name> --region <region_name>

but even with this, tags were not applied to ENIs.

[1] https://docs.aws.amazon.com/cli/latest/reference/autoscaling/create-or-update-tags.html

It would be great if this capability could be automated.

+1 Please add this. I had a 1 to many relationship (Policy-> Role) with a multi-tenant set up and faced an issue for a week because the ENI tags were not being created.

Public IP v4 addresses have become a paid service. Adding a tag to the ENI is a convenient way to distinguish the cost. Hope this feature can release asap.
