Deregistering a cluster

If you are finished using a connected cluster, you can deregister it. After it's deregistered, the cluster is no longer visible in the Amazon EKS console.

You must have the following permissions to call the deregisterCluster API:

• eks:DeregisterCluster

• ssm:DeleteActivation

• ssm:DeregisterManagedInstance

This process involves two steps: Deregistering the cluster with Amazon EKS and uninstalling the eks-connector agent in the cluster.

To deregister the Kubernetes cluster

AWS CLI

Prerequisites

• AWS CLI must be installed. To install or upgrade it, see Installing the AWS CLI.

• Ensure the Amazon EKS Connector agent role was created. .

Deregister the connected cluster.

aws eks deregister-cluster \
    --name my-cluster \
    --region region-code

AWS Management Console

1. Open the Amazon EKS console at https://console.aws.amazon.com/eks/home#/clusters.

2. Choose Clusters.

3. On the Clusters page, select the connected cluster and select Deregister.

4. Confirm that you want to deregister the cluster.

eksctl

Prerequisites

• eksctl version 0.68 or later must be installed. To install or upgrade it, see Getting started with Amazon EKS – eksctl.

• Ensure the Amazon EKS Connector agent role was created. .

To deregister your cluster with eksctl

• For the Connector configuration, specify your Amazon EKS Connector agent IAM role. For more information, see Required IAM roles for Amazon EKS Connector.

  eksctl deregister cluster --name my-cluster

To clean up the resources in your Kubernetes cluster

Helm

• Run the following command to uninstall the agent.

  helm -n eks-connector uninstall eks-connector

YAML manifest

1. Delete the Amazon EKS Connector YAML file from your Kubernetes cluster.

   kubectl delete -f eks-connector.yaml

2. If you created clusterrole or clusterrolebindings for additional IAM principals to access the cluster, delete them from your Kubernetes cluster.
