Document differences between (var.worker_groups, var.worker_groups_launch_template) Workers Groups and (var.node_groups) Managed Node Groups

Whats the difference between Workers and Nodes?

First, my apologies if this is not the place for these kind of questions.

I was wondering if anyone can point me some basic differences between Worker groups and Node groups. If I create a node group, I am able to see it from the AWS console in the "compute" section of the cluster. But if I create a worker-group, I only see it if I query the cluster with kubectl get nodes.

Thanks!

worker_nodes are "self-managed" node groups, while node_groups are AWS-managed node-groups. It would be nice to have a renaming of these variables to make the distinction a bit more clearer. For more info, I suggest you look at the official docs: https://docs.aws.amazon.com/eks/latest/userguide/eks-compute.html

Thank you! Cristal clear.

Also it would be fair to mention that node_groups don't allow you to use spot instances.

Can someone update the FAQ to explain this difference please ?

This is a duplicate of #895
but this module does need some better documentation (FAQ update?) so it doesn't continue to keep getting asked.

Yep. I'll happy to review and merge the PR.

Sure, I can write something up when I find free time.

Maybe @pranas #895 (comment) ?

Sorry, I lost track of this promise. I'm gonna do it right now and open PR so everyone can pitch in on what exactly should be there.

Closing this since #1081 is now merged.
