CreatePodIdentityAssociation

Creates an EKS Pod Identity association between a service account in an Amazon EKS cluster and an IAM role with EKS Pod Identity. Use EKS Pod Identity to give temporary IAM credentials to pods and the credentials are rotated automatically.

Amazon EKS Pod Identity associations provide the ability to manage credentials for your applications, similar to the way that Amazon EC2 instance profiles provide credentials to Amazon EC2 instances.

If a pod uses a service account that has an association, Amazon EKS sets environment variables in the containers of the pod. The environment variables configure the AWS SDKs, including the AWS Command Line Interface, to use the EKS Pod Identity credentials.

Pod Identity is a simpler method than IAM roles for service accounts, as this method doesn't use OIDC identity providers. Additionally, you can configure a role for Pod Identity once, and reuse it across clusters.

URI Request Parameters

The request uses the following URI parameters.

name

The name of the cluster to create the association in.

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

namespace

The name of the Kubernetes namespace inside the cluster to create the association in. The service account and the pods that use the service account must be in this namespace.

Type: String

Required: Yes

roleArn

The Amazon Resource Name (ARN) of the IAM role to associate with the service account. The EKS Pod Identity agent manages credentials to assume this role for applications in the containers in the pods that use this service account.

Type: String

Required: Yes

serviceAccount

The name of the Kubernetes service account inside the cluster to associate the IAM credentials with.

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.

The following basic restrictions apply to tags:

Maximum number of tags per resource – 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length – 128 Unicode characters in UTF-8
Maximum value length – 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

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
