/clusters/{name}/node-groups/{nodegroupName}/update-version
http://eks.{region}.amazonaws.com/clusters/{name}/node-groups/{nodegroupName}/update-version<p>Updates the Kubernetes version or AMI version of an Amazon EKS managed node group.</p> <p>You can update a node group using a launch template only if the node group was originally deployed with a launch template. If you need to update a custom AMI in a node group that was deployed with a launch template, then update your custom AMI, specify the new ID in a new version of the launch template, and then update the node group to the new version of the launch template.</p> <p>If you update without a launch template, then you can update to the latest available AMI version of a node group's current Kubernetes version by not specifying a Kubernetes version in the request. You can update to the latest AMI version of your cluster's current Kubernetes version by specifying your cluster's Kubernetes version in the request. For information about Linux versions, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/eks-linux-ami-versions.html">Amazon EKS optimized Amazon Linux AMI versions</a> in the <i>Amazon EKS User Guide</i>. For information about Windows versions, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/eks-ami-versions-windows.html">Amazon EKS optimized Windows AMI versions</a> in the <i>Amazon EKS User Guide</i>. </p> <p>You cannot roll back a node group to an earlier Kubernetes version or AMI version.</p> <p>When a node in a managed node group is terminated due to a scaling action or update, the pods in that node are drained first. Amazon EKS attempts to drain the nodes gracefully and will fail if it is unable to do so. You can <code>force</code> the update if Amazon EKS is unable to drain the nodes as a result of a pod disruption budget issue.</p>
Path Parameters
The name of the Amazon EKS cluster that is associated with the managed node group to update.
The name of the managed node group to update.
Body Params
Force the update if the existing node group's pods are unable to be drained due to a pod disruption budget issue. If an update fails because pods could not be drained, you can force the update after it fails to terminate the old node whether or not any pods are running on the node.
The Kubernetes version to update to. If no version is specified, then the Kubernetes version of the node group does not change. You can specify the Kubernetes version of the cluster to update the node group to the latest AMI version of the cluster's Kubernetes version. If you specify <code>launchTemplate</code>, and your launch template uses a custom AMI, then don't specify <code>version</code>, or the node group update will fail. For more information about using launch templates with Amazon EKS, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html">Launch template support</a> in the <i>Amazon EKS User Guide</i>.
<p>An object representing a node group launch template specification. The launch template can't include <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateNetworkInterface.html"> <code>SubnetId</code> </a>, <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_IamInstanceProfile.html"> <code>IamInstanceProfile</code> </a>, <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_RequestSpotInstances.html"> <code>RequestSpotInstances</code> </a>, <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_HibernationOptionsRequest.html"> <code>HibernationOptions</code> </a>, or <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_TerminateInstances.html"> <code>TerminateInstances</code> </a>, or the node group deployment or update will fail. For more information about launch templates, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateLaunchTemplate.html"> <code>CreateLaunchTemplate</code> </a> in the Amazon EC2 API Reference. For more information about using launch templates with Amazon EKS, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html">Launch template support</a> in the <i>Amazon EKS User Guide</i>.</p> <p>You must specify either the launch template ID or the launch template name in the request, but not both.</p>
<p>The AMI version of the Amazon EKS optimized AMI to use for the update. By default, the latest available AMI version for the node group's Kubernetes version is used. For information about Linux versions, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/eks-linux-ami-versions.html">Amazon EKS optimized Amazon Linux AMI versions</a> in the <i>Amazon EKS User Guide</i>. Amazon EKS managed node groups support the November 2022 and later releases of the Windows AMIs. For information about Windows versions, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/eks-ami-versions-windows.html">Amazon EKS optimized Windows AMI versions</a> in the <i>Amazon EKS User Guide</i>.</p> <p>If you specify <code>launchTemplate</code>, and your launch template uses a custom AMI, then don't specify <code>releaseVersion</code>, or the node group update will fail. For more information about using launch templates with Amazon EKS, see <a href="https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html">Launch template support</a> in the <i>Amazon EKS User Guide</i>.</p>
