CreateCluster

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.

Array Members: Maximum number of 1 item.

Required: No

kubernetesNetworkConfig

The Kubernetes network configuration for the cluster.

Type: KubernetesNetworkConfigRequest object

Required: No

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.

Type: Logging object

Required: No

name

The unique name to give to your cluster.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 100.

Pattern: ^[0-9A-Za-z][A-Za-z0-9\-_]*

Required: Yes

resourcesVpcConfig

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.

Type: VpcConfigRequest object

Required: Yes

roleArn

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

Type: String

Required: Yes

tags

The metadata to apply to the cluster to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define.

Type: String to string map

Map Entries: Maximum number of 50 items.

Key Length Constraints: Minimum length of 1. Maximum length of 128.

Value Length Constraints: Maximum length of 256.

Required: No

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: String

Required: No

Type: Cluster object

Errors

For information about the errors that are common to all actions, see Common Errors.

ClientException

These errors are usually caused by a client action. Actions can include using an action or resource on behalf of a user that doesn't have permissions to use the action or resource or specifying an identifier that is not valid.

HTTP Status Code: 400

InvalidParameterException

The specified parameter is invalid. Review the available parameters for the API request.

HTTP Status Code: 400

ResourceInUseException

The specified resource is in use.

HTTP Status Code: 409

ResourceLimitExceededException

You have encountered a service limit on the specified resource.

HTTP Status Code: 400

ServerException

These errors are usually caused by a server-side issue.

HTTP Status Code: 500

ServiceUnavailableException

The service is unavailable. Back off and retry the operation.

HTTP Status Code: 503

UnsupportedAvailabilityZoneException

At least one of your specified cluster subnets is in an Availability Zone that does not support Amazon EKS. The exception output specifies the supported Availability Zones for your account, from which you can choose subnets for your cluster.

HTTP Status Code: 400

Examples

In the following example or examples, the Authorization header contents (AUTHPARAMS) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You need to learn how to sign HTTP requests only if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

Example

The following example creates an Amazon EKS cluster called prod with endpoint public and private access enabled.
