Associates an identity provider configuration to a cluster.

If you want to authenticate identities using an identity provider, you can create an identity provider configuration and associate it to your cluster. After configuring authentication to your cluster you can create Kubernetes Role and ClusterRole objects, assign permissions to them, and then bind them to the identities using Kubernetes RoleBinding and ClusterRoleBinding objects. For more information see Using RBAC Authorization in the Kubernetes documentation.

--cluster-name (string)

The name of your cluster.

--oidc (structure)

An object representing an OpenID Connect (OIDC) identity provider configuration.

identityProviderConfigName -> (string)

The name of the OIDC provider configuration.

issuerUrl -> (string)

The URL of the OIDC identity provider that allows the API server to discover public signing keys for verifying tokens. The URL must begin with https:// and should correspond to the iss claim in the provider’s OIDC ID tokens. Based on the OIDC standard, path components are allowed but query parameters are not. Typically the URL consists of only a hostname, like https://server.example.org or https://example.com . This URL should point to the level below .well-known/openid-configuration and must be publicly accessible over the internet.

clientId -> (string)

This is also known as audience . The ID for the client application that makes authentication requests to the OIDC identity provider.

usernameClaim -> (string)

The JSON Web Token (JWT) claim to use as the username. The default is sub , which is expected to be a unique identifier of the end user. You can choose other claims, such as email or name , depending on the OIDC identity provider. Claims other than email are prefixed with the issuer URL to prevent naming clashes with other plug-ins.

usernamePrefix -> (string)

The prefix that is prepended to username claims to prevent clashes with existing names. If you do not provide this field, and username is a value other than email , the prefix defaults to issuerurl# . You can use the value - to disable all prefixing.

groupsClaim -> (string)

The JWT claim that the provider uses to return your groups.

groupsPrefix -> (string)

The prefix that is prepended to group claims to prevent clashes with existing names (such as system: groups). For example, the value``oidc:`` will create group names like oidc:engineering and oidc:infra .

requiredClaims -> (map)

The key value pairs that describe required claims in the identity token. If set, each claim is verified to be present in the token with a matching value. For the maximum number of claims that you can require, see Amazon EKS service quotas in the Amazon EKS User Guide .

key -> (string)

value -> (string)

Shorthand Syntax:


JSON Syntax:

  "identityProviderConfigName": "string",
  "issuerUrl": "string",
  "clientId": "string",
  "usernameClaim": "string",
  "usernamePrefix": "string",
  "groupsClaim": "string",
  "groupsPrefix": "string",
  "requiredClaims": {"string": "string"

--tags (map)

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.

key -> (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.

value -> (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).

Shorthand Syntax:


JSON Syntax:

{"string": "string"

--client-request-token (string)

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

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.



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 .
