update-nodegroup-version

Description

Updates the Kubernetes version or AMI version of an Amazon EKS managed node group.

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.

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 more information, see Amazon EKS optimized Amazon Linux 2 AMI versions in the Amazon EKS User Guide .

You cannot roll back a node group to an earlier Kubernetes version or AMI version.

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 force the update if Amazon EKS is unable to drain the nodes as a result of a pod disruption budget issue.

Options

--cluster-name (string)

The name of the Amazon EKS cluster that is associated with the managed node group to update.

--nodegroup-name (string)

The name of the managed node group to update.

--release-version (string)

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 more information, see Amazon EKS optimized Amazon Linux 2 AMI versions in the Amazon EKS User Guide . If you specify launchTemplate , and your launch template uses a custom AMI, then don’t specify releaseVersion , or the node group update will fail. For more information about using launch templates with Amazon EKS, see Launch template support in the Amazon EKS User Guide.

--launch-template (structure)

An object representing a node group’s launch template specification. You can only update a node group using a launch template if the node group was originally deployed with a launch template.

name -> (string)

The name of the launch template.

version -> (string)

The version of the launch template to use. If no version is specified, then the template’s default version is used.

id -> (string)

The ID of the launch template.

Shorthand Syntax:

name=string,version=string,id=string

JSON Syntax:

{
  "name": "string",
  "version": "string",
  "id": "string"
}

--force | --no-force (boolean)

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.

--client-request-token (string)

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request.

--kubernetes-version (string)

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 launchTemplate , and your launch template uses a custom AMI, then don’t specify version , or the node group update will fail. For more information about using launch templates with Amazon EKS, see Launch template support in the Amazon EKS User Guide.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.
