create-cluster¶

Description¶

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.

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 Managing Cluster Authentication and Launching Amazon EKS nodes in the Amazon EKS User Guide .

Options¶

--name (string)

The unique name to give to your cluster.

--role-arn (string)

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 * .

--resources-vpc-config (structure)

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:

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 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 and you have nodes or 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", ...]
}

--kubernetes-network-config (structure)

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 and can’t change this value once 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.

Shorthand Syntax:

serviceIpv4Cidr=string,ipFamily=string

JSON Syntax:

{
  "serviceIpv4Cidr": "string",
  "ipFamily": "ipv4"|"ipv6"
}

--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 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.

--tags (map)

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

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--encryption-config (list)

The encryption configuration for the cluster.

(structure)

The encryption configuration for the cluster.

resources -> (list)

Specifies the resources to be encrypted. The only supported value is “secrets”.

(string)

provider -> (structure)

Key Management Service (KMS) key. Either the ARN or the alias can be used.

keyArn -> (string)

Amazon Resource Name (ARN) or alias of the KMS key. The KMS key must be symmetric, created in the same region as the cluster, and if the KMS key was created in a different account, the user must have access to the KMS key. For more information, see Allowing Users in Other Accounts to Use a KMS key in the Key Management Service Developer Guide .

Shorthand Syntax:

resources=string,string,provider={keyArn=string} ...

JSON Syntax:

[
  {
    "resources": ["string", ...],
    "provider": {
      "keyArn": "string"
    }
  }
  ...
]

--kubernetes-version (string)

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

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
