[ aws . eks ]



Updates an Amazon EKS managed node group configuration. Your node group continues to function during the update. The response output includes an update ID that you can use to track the status of your node group update with the DescribeUpdate API operation. Currently you can update the Kubernetes labels for a node group or the scaling configuration.

--cluster-name (string)

The name of the Amazon EKS cluster that the managed node group resides in.

--nodegroup-name (string)

The name of the managed node group to update.

--labels (structure)

The Kubernetes labels to be applied to the nodes in the node group after the update.

addOrUpdateLabels -> (map)

Kubernetes labels to be added or updated.

key -> (string)

value -> (string)

removeLabels -> (list)

Kubernetes labels to be removed.


Shorthand Syntax:


JSON Syntax:

  "addOrUpdateLabels": {"string": "string"
  "removeLabels": ["string", ...]

--scaling-config (structure)

The scaling configuration details for the Auto Scaling group after the update.

minSize -> (integer)

The minimum number of worker nodes that the managed node group can scale in to. This number must be greater than zero.

maxSize -> (integer)

The maximum number of worker nodes that the managed node group can scale out to. Managed node groups can support up to 100 nodes by default.

desiredSize -> (integer)

The current number of worker nodes that the managed node group should maintain.

JSON Syntax:

  "minSize": integer,
  "maxSize": integer,
  "desiredSize": integer

--client-request-token (string)

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

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.
