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

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

And then the aws eks list-addons command can be used to list the Add Ons.

~]$ aws eks list-addons --cluster-name my-cluster
{
    "addons": [
        "my-add-ons"
    ]
}

And then the aws eks describe-addon command can be used to show more details about an Add On.

~]$ aws eks describe-addon --cluster my-cluster --addon-name my-add-on
{
    "addon": {
        "addonName": "my-add-on",
        "clusterName": "my-cluster",
        "status": "ACTIVE",
        "addonVersion": "v1.15.1-eksbuild.1",
