Creates an Amazon EKS control plane.

The Amazon EKS control plane consists of control plane instances that run the Kubernetes software, such as etcd and the API server. The control plane runs in an account managed by AWS, and the Kubernetes API is exposed via the Amazon EKS API server endpoint. Each Amazon EKS cluster control plane is single-tenant and unique and runs on its own set of Amazon EC2 instances.

The cluster control plane is provisioned across multiple Availability Zones and fronted by an Elastic Load Balancing Network Load Balancer. Amazon EKS also provisions elastic network interfaces in your VPC subnets to provide connectivity from the control plane instances to the worker nodes (for example, to support kubectl exec , logs , and proxy data flows).

Amazon EKS worker nodes run in your AWS account and connect to your cluster's control plane via the Kubernetes API server endpoint and a certificate file that is created for your cluster.

You can use the endpointPublicAccess and endpointPrivateAccess parameters 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 * .

You can use the logging parameter 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 .

Cluster creation typically takes between 10 and 15 minutes. After you create an Amazon EKS cluster, you must configure your Kubernetes tooling to communicate with the API server and launch worker nodes into your cluster. For more information, see Managing Cluster Authentication and Launching Amazon EKS Worker Nodes in the Amazon EKS User Guide .

type name

string

param name

[REQUIRED]

The unique name to give to your cluster.

type version

string

param version

The desired Kubernetes version for your cluster. If you don't specify a value here, the latest version available in Amazon EKS is used.

type roleArn

string

param roleArn

[REQUIRED]

The Amazon Resource Name (ARN) of the IAM role that provides permissions for Amazon EKS to make calls to other AWS API operations on your behalf. For more information, see Amazon EKS Service IAM Role in the * Amazon EKS User Guide * .

type resourcesVpcConfig

dict

param resourcesVpcConfig

[REQUIRED]

The VPC configuration used by the cluster control plane. Amazon EKS VPC resources have specific requirements to work properly with Kubernetes. For more information, see Cluster VPC Considerations and Cluster Security Group Considerations in the Amazon EKS User Guide . You must specify at least two subnets. You can specify up to five security groups, but we recommend that you use a dedicated security group for your cluster control plane.

  • 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 a security group, the default security group for your VPC is used.

    • (string) --

  • endpointPublicAccess (boolean) --

    Set this value to false to disable public access for your cluster's Kubernetes API server endpoint. If you disable public access, your cluster's Kubernetes API server can receive only 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. For more information, see Amazon EKS Cluster Endpoint Access Control in the * Amazon EKS User Guide * .

type logging

dict

param logging

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.

    • (dict) --

      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.

type clientRequestToken

string

param clientRequestToken

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

This field is autopopulated if not provided.

DeleteCluster (updated) Link ¶
Changes (response)
{'cluster': {'identity': {'oidc': {'issuer': 'string'}}}}

Deletes the Amazon EKS cluster control plane.

Note

If you have active services in your cluster that are associated with a load balancer, you must delete those services before deleting the cluster so that the load balancers are deleted properly. Otherwise, you can have orphaned resources in your VPC that prevent you from being able to delete the VPC. For more information, see Deleting a Cluster in the Amazon EKS User Guide .

Returns descriptive information about an Amazon EKS cluster.

The API server endpoint and certificate authority data returned by this operation are required for kubelet and kubectl to communicate with your Kubernetes API server. For more information, see Create a kubeconfig for Amazon EKS .

Note
