create_cluster#

EKS.Client.create_cluster(**kwargs)#

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 Amazon Web Services, and the Kubernetes API is exposed by the Amazon EKS API server endpoint. Each Amazon EKS cluster control plane is single tenant and unique. It 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 nodes (for example, to support kubectl exec, logs, and proxy data flows).

Amazon EKS nodes run in your Amazon Web Services account and connect to your cluster’s control plane over 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 CloudWatch Pricing.

In most cases, it takes several minutes to create a cluster. After you create an Amazon EKS cluster, you must configure your Kubernetes tooling to communicate with the API server and launch nodes into your cluster. For more information, see Allowing users to access your cluster and Launching Amazon EKS nodes in the Amazon EKS User Guide.

Parameters:
  • name (string) –

    [REQUIRED]

    The unique name to give to your cluster.

  • version (string) –

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

    Note

    The default version might not be the latest version available.

  • roleArn (string) –

    [REQUIRED]

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

  • resourcesVpcConfig (dict) –

    [REQUIRED]

    The VPC configuration that’s 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. However, we recommend that you use a dedicated security group for your cluster control plane.

    • subnetIds (list) –

      Specify subnets for your Amazon EKS nodes. Amazon EKS creates cross-account elastic network interfaces in these subnets to allow communication between your 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 that allow communication between your 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. 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 nodes or Fargate pods in the cluster, then ensure that publicAccessCidrs includes the necessary CIDR blocks for communication with the 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, make sure that you specify the necessary CIDR blocks for every node and Fargate Pod in the cluster. For more information, see Amazon EKS cluster endpoint access control in the Amazon EKS User Guide .

      • (string) –

  • kubernetesNetworkConfig (dict) –

    The Kubernetes network configuration for the cluster.

    • serviceIpv4Cidr (string) –

      Don’t specify a value if you select ipv6 for ipFamily. The CIDR block to assign Kubernetes service IP addresses from. If you don’t specify a block, Kubernetes assigns addresses from either the 10.100.0.0/16 or 172.20.0.0/16 CIDR blocks. We recommend that you specify a block that does not overlap with resources in other networks that are peered or connected to your VPC. The block must meet the following requirements:

      • Within one of the following private IP address blocks: 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16.

      • Doesn’t overlap with any CIDR block assigned to the VPC that you selected for VPC.

      • Between /24 and /12.

      Warning

      You can only specify a custom CIDR block when you create a cluster. You can’t change this value after the cluster is created.

    • ipFamily (string) –

      Specify which IP family is used to assign Kubernetes pod and service IP addresses. If you don’t specify a value, ipv4 is used by default. You can only specify an IP family when you create a cluster and can’t change this value once the cluster is created. If you specify ipv6, the VPC and subnets that you specify for cluster creation must have both IPv4 and IPv6 CIDR blocks assigned to them. You can’t specify ipv6 for clusters in China Regions.

      You can only specify ipv6 for 1.21 and later clusters that use version 1.10.1 or later of the Amazon VPC CNI add-on. If you specify ipv6, then ensure that your VPC meets the requirements listed in the considerations listed in Assigning IPv6 addresses to pods and services in the Amazon EKS User Guide. Kubernetes assigns services IPv6 addresses from the unique local address range (fc00::/7). You can’t specify a custom IPv6 CIDR block. Pod addresses are assigned from the subnet’s IPv6 CIDR.

  • logging (dict) –

    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 CloudWatch Pricing.

    • clusterLogging (list) –

          • (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.

  • clientRequestToken (string) –

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

    This field is autopopulated if not provided.

  • tags (dict) –

    Metadata that assists with categorization and organization. Each tag consists of a key and an optional value. You define both. Tags don’t propagate to any other cluster or Amazon Web Services resources.

    • (string) –

      One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

      • (string) –

        The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
