Example usage for com.amazonaws.auth InstanceProfileCredentialsProvider InstanceProfileCredentialsProvider

Introduction

In this page you can find the example usage for com.amazonaws.auth InstanceProfileCredentialsProvider InstanceProfileCredentialsProvider.

Prototype

public InstanceProfileCredentialsProvider(boolean refreshCredentialsAsync) 

Source Link

Document

Spins up a new thread to refresh the credentials asynchronously if refreshCredentialsAsync is set to true, otherwise the credentials will be refreshed from the instance metadata service synchronously,

It is strongly recommended to reuse instances of this credentials provider, especially when async refreshing is used since a background thread is created.
