New Datasource: AWS EKS release version for node groups

[BornToBeRoot]

Hi all,

to upgrade an EKS cluster you need the release version for the node group. The new data source would be similar to the data source for ami image or eks addons.

In Terraform it looks like this:

resource "aws_eks_node_group" "default" {
...
version = "1.29"
ami_type = "AL2023_x86_64_STANDARD"
release_version = "1.29.10-20241205" # This value is stored in aws ssm
...
}

You can get the value from AWS SSM:

aws ssm get-parameter \
 --name "/aws/service/eks/optimized-ami/1.29/amazon-linux-2023/x86_64/standard/recommended/release_version"

aws ssm get-parameter \
 --name "/aws/service/eks/optimized-ami/1.29/amazon-linux-2023/x86_64/standard/recommended/release_version" \
 --query "Parameter.Value" \
 --output text

1.29.10-20241205

Maybe the EKS Version, AMI Type, etc. can be configured with a comment similar to the aws ami datasource.

Should these continue to be separate datasources, or is the potential to combine them if we make them more generic?

[BornToBeRoot]

I think it should be separate, because it is different from an EKS add-on or an AMI ID.

How many such "different" datasources would be likely to have in future from AWS? e.g. today we have 3, but what's the maximum number?

I don't currently have any use cases apart from these three. I also don't know which other ones exist.

I am also not sure how hard it is to maintain if you combine everything AWS related into one datasource. The use cases are different, even if you get most of the data from aws ssm.
