CreateAccessEntry

Creates an access entry.

An access entry allows an IAM principal to access your cluster. Access entries can replace the need to maintain entries in the aws-auth ConfigMap for authentication. You have the following options for authorizing an IAM principal to access Kubernetes objects on your cluster: Kubernetes role-based access control (RBAC), Amazon EKS, or both. Kubernetes RBAC authorization requires you to create and manage Kubernetes Role, ClusterRole, RoleBinding, and ClusterRoleBinding objects, in addition to managing access entries. If you use Amazon EKS authorization exclusively, you don't need to create and manage Kubernetes Role, ClusterRole, RoleBinding, and ClusterRoleBinding objects.

For more information about access entries, see Access entries in the Amazon EKS User Guide.

Request Syntax


POST /clusters/name/access-entries HTTP/1.1
Content-type: application/json

{
   "clientRequestToken": "string",
   "kubernetesGroups": [ "string" ],
   "principalArn": "string",
   "tags": { 
      "string" : "string" 
   },
   "type": "string",
   "username": "string"
}

URI Request Parameters

The request uses the following URI parameters.

name

The name of your cluster.

Required: Yes

Request Body

The request accepts the following data in JSON format.

clientRequestToken

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

Type: String

Required: No

kubernetesGroups

The value for name that you've specified for kind: Group as a subject in a Kubernetes RoleBinding or ClusterRoleBinding object. Amazon EKS doesn't confirm that the value for name exists in any bindings on your cluster. You can specify one or more names.

Kubernetes authorizes the principalArn of the access entry to access any cluster objects that you've specified in a Kubernetes Role or ClusterRole object that is also specified in a binding's roleRef. For more information about creating Kubernetes RoleBinding, ClusterRoleBinding, Role, or ClusterRole objects, see Using RBAC Authorization in the Kubernetes documentation.

If you want Amazon EKS to authorize the principalArn (instead of, or in addition to Kubernetes authorizing the principalArn), you can associate one or more access policies to the access entry using AssociateAccessPolicy. If you associate any access policies, the principalARN has all permissions assigned in the associated access policies and all permissions in any Kubernetes Role or ClusterRole objects that the group names are bound to.

Type: Array of strings

Required: No

principalArn

The ARN of the IAM principal for the AccessEntry. You can specify one ARN for each access entry. You can't specify the same ARN in more than one access entry. This value can't be changed after access entry creation.

The valid principals differ depending on the type of the access entry in the type field. The only valid ARN is IAM roles for the types of access entries for nodes: . You can use every IAM principal type for STANDARD access entries. You can't use the STS session principal type with access entries because this is a temporary principal for each session and not a permanent identity that can be assigned permissions.

IAM best practices recommend using IAM roles with temporary credentials, rather than IAM users with long-term credentials.

Type: String

Required: Yes

tags

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 AWS resources.

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

type

The type of the new access entry. Valid values are Standard, FARGATE_LINUX, EC2_LINUX, and EC2_WINDOWS.

If the principalArn is for an IAM role that's used for self-managed Amazon EC2 nodes, specify EC2_LINUX or EC2_WINDOWS. Amazon EKS grants the necessary permissions to the node for you. If the principalArn is for any other purpose, specify STANDARD. If you don't specify a value, Amazon EKS sets the value to STANDARD. It's unnecessary to create access entries for IAM roles used with Fargate profiles or managed Amazon EC2 nodes, because Amazon EKS creates entries in the aws-auth ConfigMap for the roles. You can't change this value once you've created the access entry.

If you set the value to EC2_LINUX or EC2_WINDOWS, you can't specify values for kubernetesGroups, or associate an AccessPolicy to the access entry.

Type: String

Required: No

username

The username to authenticate to Kubernetes with. We recommend not specifying a username and letting Amazon EKS specify it for you. For more information about the value Amazon EKS specifies for you, or constraints before specifying your own username, see Creating access entries in the Amazon EKS User Guide.

Type: String

Required: No

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

accessEntry

An access entry allows an IAM principal (user or role) to access your cluster. Access entries can replace the need to maintain the aws-auth ConfigMap for authentication. For more information about access entries, see Access entries in the Amazon EKS User Guide.

Type: AccessEntry object

Errors

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

InvalidParameterException

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

HTTP Status Code: 400

InvalidRequestException

The request is invalid given the state of the cluster. Check the state of the cluster and the associated operations.

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

ResourceNotFoundException

The specified resource could not be found. You can view your available clusters with ListClusters. You can view your available managed node groups with ListNodegroups. Amazon EKS clusters and node groups are AWS Region specific.

HTTP Status Code: 404

ServerException

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

HTTP Status Code: 500

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 Amazon EKS 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 access entry for an IAM role with the name my-role. Since a type isn't specified, it's created as type Standard. Since a username isn't specified, Amazon EKS sets the value for username.
