Release Notes

Release: AWS Elastic Beanstalk introduces a maintenance service-linked role on April 18, 2019

Elastic Beanstalk added a new service-linked role for maintenance, to join the monitoring service-linked role already in use.

Release date: April 18, 2019

Changes

AWS Elastic Beanstalk uses AWS Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to Elastic Beanstalk. Service-linked roles are predefined by Elastic Beanstalk and include all the permissions that the service requires to call other AWS services on your behalf.

A service-linked role makes setting up an Elastic Beanstalk environment easier because you don’t have to manually add the necessary permissions. Elastic Beanstalk defines the permissions of its service-linked roles, and unless defined otherwise, only Elastic Beanstalk can assume its roles.

Elastic Beanstalk already supports a monitoring service-linked role, which it uses for health monitoring and event reporting when no explicit service role is specified during environment creation. Today's release adds a maintenance service-linked role, which Elastic Beanstalk will associate with environments that need regular maintenance activities. At this time, Elastic Beanstalk will use a maintenance service-linked role with environments that don't have an instance profile, as an alternative way to retrieve your application source code from Amazon Simple Storage Service (Amazon S3) during deployment.

For more information, see Using Service-Linked Roles for Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide.
