update-cluster-config¶

Description¶

Updates an Amazon EKS cluster configuration. Your cluster continues to function during the update. The response output includes an update ID that you can use to track the status of your cluster update with the DescribeUpdate API operation.

You can use this API operation to enable or disable exporting the Kubernetes control plane logs for your cluster to CloudWatch Logs. By default, cluster control plane logs aren’t exported to CloudWatch Logs. For more information, see Amazon EKS Cluster Control Plane Logs in the * Amazon EKS User Guide * .

Note

CloudWatch Logs ingestion, archive storage, and data scanning rates apply to exported control plane logs. For more information, see Amazon CloudWatch Pricing .

You can also use this API operation to enable or disable public and private access to your cluster’s Kubernetes API server endpoint. By default, public access is enabled, and private access is disabled. For more information, see Amazon EKS Cluster Endpoint Access Control in the * Amazon EKS User Guide * .

Warning

At this time, you can not update the subnets or security group IDs for an existing cluster.

Cluster updates are asynchronous, and they should finish within a few minutes. During an update, the cluster status moves to UPDATING (this status transition is eventually consistent). When the update is complete (either Failed or Successful ), the cluster status moves to Active .

Synopsis¶

  update-cluster-config
--name <value>
[--resources-vpc-config <value>]
[--logging <value>]
[--client-request-token <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--name (string)

The name of the Amazon EKS cluster to update.

--resources-vpc-config (structure)

An object representing the VPC configuration to use for an Amazon EKS cluster.

subnetIds -> (list)

Specify subnets for your Amazon EKS worker nodes. Amazon EKS creates cross-account elastic network interfaces in these subnets to allow communication between your worker nodes and the Kubernetes control plane.

(string)

securityGroupIds -> (list)

Specify one or more security groups for the cross-account elastic network interfaces that Amazon EKS creates to use to allow communication between your worker nodes and the Kubernetes control plane. If you don’t specify any security groups, then familiarize yourself with the difference between Amazon EKS defaults for clusters deployed with Kubernetes:

1.14 Amazon EKS platform version eks.2 and earlier

1.14 Amazon EKS platform version eks.3 and later

For more information, see Amazon EKS security group considerations in the * Amazon EKS User Guide * .

(string)

endpointPublicAccess -> (boolean)

Set this value to false to disable public access to your cluster’s Kubernetes API server endpoint. If you disable public access, your cluster’s Kubernetes API server can only receive requests from within the cluster VPC. The default value for this parameter is true , which enables public access for your Kubernetes API server. For more information, see Amazon EKS Cluster Endpoint Access Control in the * Amazon EKS User Guide * .

endpointPrivateAccess -> (boolean)

Set this value to true to enable private access for your cluster’s Kubernetes API server endpoint. If you enable private access, Kubernetes API requests from within your cluster’s VPC use the private VPC endpoint. The default value for this parameter is false , which disables private access for your Kubernetes API server. If you disable private access and you have worker nodes or AWS Fargate pods in the cluster, then ensure that publicAccessCidrs includes the necessary CIDR blocks for communication with the worker nodes or Fargate pods. For more information, see Amazon EKS Cluster Endpoint Access Control in the * Amazon EKS User Guide * .

publicAccessCidrs -> (list)

The CIDR blocks that are allowed access to your cluster’s public Kubernetes API server endpoint. Communication to the endpoint from addresses outside of the CIDR blocks that you specify is denied. The default value is 0.0.0.0/0 . If you’ve disabled private endpoint access and you have worker nodes or AWS Fargate pods in the cluster, then ensure that you specify the necessary CIDR blocks. For more information, see Amazon EKS Cluster Endpoint Access Control in the * Amazon EKS User Guide * .

(string)

Shorthand Syntax:

subnetIds=string,string,securityGroupIds=string,string,endpointPublicAccess=boolean,endpointPrivateAccess=boolean,publicAccessCidrs=string,string

JSON Syntax:

{
  "subnetIds": ["string", ...],
  "securityGroupIds": ["string", ...],
  "endpointPublicAccess": true|false,
  "endpointPrivateAccess": true|false,
  "publicAccessCidrs": ["string", ...]
}

--logging (structure)

Enable or disable exporting the Kubernetes control plane logs for your cluster to CloudWatch Logs. By default, cluster control plane logs aren’t exported to CloudWatch Logs. For more information, see Amazon EKS Cluster Control Plane Logs in the * Amazon EKS User Guide * .

Note

CloudWatch Logs ingestion, archive storage, and data scanning rates apply to exported control plane logs. For more information, see Amazon CloudWatch Pricing .

clusterLogging -> (list)

The cluster control plane logging configuration for your cluster.

(structure)

An object representing the enabled or disabled Kubernetes control plane logs for your cluster.

types -> (list)

The available cluster control plane log types.

(string)

enabled -> (boolean)

If a log type is enabled, that log type exports its control plane logs to CloudWatch Logs. If a log type isn’t enabled, that log type doesn’t export its control plane logs. Each individual log type can be enabled or disabled independently.

JSON Syntax:

{
  "clusterLogging": [
    {
      "types": ["api"|"audit"|"authenticator"|"controllerManager"|"scheduler", ...],
      "enabled": true|false
    }
    ...
  ]
}

--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.

See ‘aws help’ for descriptions of global parameters.
