Description

while the resource aws_autoscaling_group has suspended_processes like:

  suspended_processes = ["AZRebalance"]

The resource aws_eks_node_group doesn't support suspended_processes

It seems that the Managed Autoscale group has this option

Can you add this support for the resource aws_eks_node_group?

Any updates on this maybe?
We've been experiencing some issues with Cluster autoscaler and AZRebalance

Same issue for me.

I can't help you on coding it, but it I was able to do it with a null_resource command using
aws autoscaling suspend-processes --auto-scaling-group-name ${each.value} --scaling-processes AZRebalance
Auto scaling group names can be accessed through terraform-provider-aws module (I used a data source however for simplicity).

Unfortunately, there's no support for passing down the desired suspended_processes through to the underlying ASG in the EKS API. Given that the underlying ASG isn't managed by Terraform, I think that @eclivus' suggestion is the best option right now. If anyone interested in this feature has a support contract with AWS it might be worth you trying to engage with your TAM to see if the feature can be put on the EKS backlog. There's a related roadmap item aws/containers-roadmap#1453 (with a similar null_resource workaround) which it might be worth folks tracking and/or providing input to.
