The results of `aws eks list-nodegroups` and `eksctl get nodegroups` are inconsistent

Question

eksctl  get nodegroups --cluster=cluster-name --profile=dev
aws eks list-nodegroups --cluster=cluster-name --profile=dev

First result is correct
Second result is air as follows:

{ 
    "nodegroups": [] 
} 

I used these two commands to get the nodegroup of the cluster, but found that the results were not consistent.
The configuration file I used was the same ~/.aws/config.
The cluster_name was checked by the command. Come out, these two commands can correctly detect cluster but cannot detect nodegroup
Thanks in advance

What versions of aws and eksctl are you using? – Fug

I installed it according to the aws document, it should be the latest version, aws-cli/2.0.38 eksctl/0.25.0 – Watanabe

Answer 1

According to eksctl documentation:

Listing nodegroups

To list the details about a nodegroup or all of the nodegroups, use:

eksctl get nodegroup --cluster=<clusterName> [--name=<nodegroupName>]

Nodegroup immutability

By design, nodegroups are immutable. This means that if you need to change something (other than scaling) like the AMI or the instance type of a nodegroup, you would need to create a new nodegroup with the desired changes, move the load and delete the old one. Check Deleting and draining.

And for list-nodegroup from AWS documentation

Lists the Amazon EKS managed node groups associated with the specified cluster in your AWS account in the specified Region. Self-managed node groups are not listed.

As you can see there are differences in these commands such as Self-managed node groups are not listed in the second command.
