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 information about Linux versions, see Amazon EKS optimized Amazon Linux AMI versions in the Amazon EKS User Guide . For information about Windows versions, see Amazon EKS optimized Windows 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, every Pod on that node is 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 your cluster.

--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 information about Linux versions, see Amazon EKS optimized Amazon Linux AMI versions in the Amazon EKS User Guide . Amazon EKS managed node groups support the November 2022 and later releases of the Windows AMIs. For information about Windows versions, see Amazon EKS optimized Windows 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.

You must specify either the launch template name or the launch template ID in the request, but not both.

version -> (string)

The version number 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.

You must specify either the launch template ID or the launch template name in the request, but not both.

Shorthand Syntax:

name=string,version=string,id=string

JSON Syntax:

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

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

Force the update if any Pod on the existing node group can’t be drained due to a Pod disruption budget issue. If an update fails because all Pods can’t be drained, you can force the update after it fails to terminate the old node whether or not any Pod is running on the node.

--client-request-token (string)

A 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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
