ListAddons - Amazon EKS

ListAddons

Lists the installed add-ons.

Request Syntax

GET /clusters/name/addons?maxResults=maxResults&nextToken=nextToken HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

name

The name of your cluster.

Length Constraints: Minimum length of 1. Maximum length of 100.

Pattern: ^[0-9A-Za-z][A-Za-z0-9\-_]*

Required: Yes

maxResults

The maximum number of results, returned in paginated output. You receive maxResults in a single page, along with a nextToken response element. You can see the remaining results of the initial request by sending another request with the returned nextToken value. This value can be between 1 and 100. If you don't use this parameter, 100 results and a nextToken value, if applicable, are returned.

Valid Range: Minimum value of 1. Maximum value of 100.

nextToken

The nextToken value returned from a previous paginated request, where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is used only to retrieve the next items in a list and not for other programmatic purposes.

Request Body

The request does not have a request body.

Response Syntax

HTTP/1.1 200
Content-type: application/json

{
   "addons": [ "string" ],
   "nextToken": "string"
}

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.

addons

A list of installed add-ons.

Type: Array of strings

nextToken

The nextToken value to include in a future ListAddons request. When the results of a ListAddons request exceed maxResults, you can use this value to retrieve the next page of results. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is used only to retrieve the next items in a list and not for other programmatic purposes.

Type: String

Errors

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

ClientException

These errors are usually caused by a client action. Actions can include using an action or resource on behalf of an IAM principal that doesn't have permissions to use the action or resource or specifying an identifier that is not valid.

HTTP Status Code: 400

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

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 lists the add-ons installed to a cluster.
