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.
