Errors

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

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

HTTP Status Code: 400

ResourceNotFoundException

The specified resource could not be found. You can view your available clusters with ListClusters. Amazon EKS clusters are Region-specific.

HTTP Status Code: 404

Example

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 AWS General Reference.

You only need to learn how to sign HTTP requests 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 describes a cluster called prod.
