AWS credentials

The S3 CSV Input step provides credentials to the Amazon Web Services SDK for Java using a credential provider chain. The default credential provider chain looks for AWS credentials in the following locations and in the following order:

• Environment variables

  The variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN. See AWS Environment Variables.

• AWS credentials file

  The credentials file, located in the /.aws directory on Linux, macOS, and Unix operating systems, and in the "%UserProfile%\.aws directory on Windows operating systems. SeeAWS Configuration and Credential Files

• CLI configuration file

  The config file is located in the same directory as the credentials file. The config file can contain a default profile, named profiles, and CLI-specific configuration parameters for each profile.

• ECS container credentials

  These credentials are provided by the Amazon Elastic Container Service on container instances set up by the ECS administrator. See AWS Using an IAM Role to Grant Permissions to Applications.

• Instance profile credentials

  These credentials are delivered through the Amazon EC2 metadata service, and can be used on EC2 instances with an assigned instance role.

The S3 CSV Input step can use any of these methods to authenticate AWS credentials. For more information on setting up AWS credentials, see Working with AWS Credentials.
