Updating kubectl on the Bastion

With the update of EKS, the kubectl binary on the bastion host must also be updated. You must use a kubectl version that is within one minor version difference of your Amazon EKS cluster control plane. For example, a 1.20 kubectl client works with Kubernetes 1.19, 1.20 and 1.21 clusters. A list of supported Kubernetes binaries can be found here.

For information on installing kubectl, see Creating and Configuring the Bastion.
