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


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


Solution

  • 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.
