Both the AWS CLI and the eksctl CLI can be used to list your Elastic Kubernetes Service (EKS) Clusters.

• aws eks list-clusters (this article)
• eksctl get clusters

The aws eks list-clusters command can be used to list your Elastic Kubernetes Service (EKS) Clusters.

~]$ aws eks list-clusters
{
    "clusters": [
        "my-cluster"
    ]
}

This will use the default profile in your hidden AWS credentials file (e.g. /home/john.doe/.aws/credentials). For example, if your hidden AWS credentials file has the following, the default credential would be used.

~]$ cat /home/john.doe/.aws/credentials 
[default]
aws_secret_access_key = ABCDEFG123456789ABCDEFG123456789ABCDEFG12
aws_access_key_id = ABCDEFG123456789ABCD

Or, the --profile flag could be used to use some other profile in your hidden AWS credentials file.

~]$ aws eks list-clusters --profile johndoe
{
    "clusters": [
        "my-cluster"
    ]
}

And then the aws eks describe-cluster command can be used to display more information about the cluster.

~]$ aws eks describe-cluster --name my-cluster
{
    "cluster": {
        "name": "my-cluster",
