             Summary: Use DefaultAWSCredentialsProviderChain to load AWS credentials from different sources
                 Key: CAMEL-15779
                 URL: https://issues.apache.org/jira/browse/CAMEL-15779
             Project: Camel
          Issue Type: Improvement
            Reporter: Alexey Minakov


Currently both [aws.s3|https://github.com/apache/camel/blob/master/components/camel-aws-s3/src/main/java/org/apache/camel/component/aws/s3/client/impl/S3ClientIAMOptimizedImpl.java#L20] and [aws2.s3|https://github.com/apache/camel/blob/master/components/camel-aws2-s3/src/main/java/org/apache/camel/component/aws2/s3/client/impl/AWS2S3ClientIAMOptimizedImpl.java#L26] IAM optimized client implementations are using a hard-coded [InstanceProfileCredentialsProvider|https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/InstanceProfileCredentialsProvider.html]. It means that you can only use it from EC2 instance, and it will not work in ECS or Fargate task. 

It will make much more sense to use a [DefaultCredentialsProviderChain|https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/DefaultAWSCredentialsProviderChain.html] ([DefaultCredentialsProvider|https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/auth/credentials/DefaultCredentialsProvider.html] for v2). In this case we will be able to use multiple methods for supplying credentials - Java System Properties, Environment Variables, Credential profiles file, Credentials delivered through the Amazon EC2 container service, 
Instance profile credentials delivered through the Amazon EC2 metadata service.
