Class: AWS.ECSCredentials

AWS.Credentials show all
Defined in:



This feature is not supported in the browser environment of the SDK.

Represents credentials received from relative URI specified in the ECS container.

This class will request refreshable credentials from the relative URI specified by the AWS_CONTAINER_CREDENTIALS_RELATIVE_URI environment variable in the container. If valid credentials are returned in the response, these will be used with zero configuration.

This credentials class will by default timeout after 1 second of inactivity and retry 3 times. If your requests to the relative URI are timing out, you can increase the value by configuring them directly:

AWS.config.credentials = new AWS.ECSCredentials({
  httpOptions: { timeout: 5000 }, // 5 second timeout
  maxRetries: 10, // retry 10 times
  retryDelayOptions: { base: 200 } // see AWS.Config for information

Method Details

refresh(callback) ⇒ void

Loads the credentials from the relative URI specified by container

Callback (callback):

  • function(err) { ... }

    Called when the request to the relative URI responds (or fails). When this callback is called with no error, it means that the credentials information has been loaded into the object (as the accessKeyId, secretAccessKey, sessionToken, and expireTime properties).


    • err (Error)

      if an error occurred, this value will be filled
