AWS-UpdateEKSManagedNodegroupVersion

Description

This runbook updates managed node groups in your Amazon EKS cluster to the latest AMI version. For more information about this update process, see Updating a managed node group in the Amazon EKS User Guide. We also recommend that you review the following topics before you use the AWS-UpdateEKSManagedNodegroupVersion runbook.

If your cluster uses autoscaling, scale the deployment down to zero replicas to avoid conflicting scaling actions.

To scale a deployment to zero replicas

  1. Install the Kubernetes command line utility, kubectl . For more information, see Installing kubectl in the Amazon EKS User Guide.

  2. Run the following command.

    kubectl scale deployments/cluster-autoscaler --replicas=0 -n kube-system
  3. Run the AWS-UpdateEKSManagedNodegroupVersion runbook.

  4. Scale the deployment back to the desired number of replicas by running the following command.

    kubectl scale deployments/cluster-autoscaler --replicas= number -n kube-system
