AWS::Greengrass::FunctionDefinition RunAs

The access identity whose permissions are used to run the Lambda function. This setting overrides the default access identity that's specified for the group (by default, ggc_user and ggc_group). You can override the user, group, or both. For more information, see Run as in the AWS IoT Greengrass Version 1 Developer Guide .

Important

Running as the root user increases risks to your data and device. Do not run as root (UID/GID=0) unless your business case requires it. For more information and requirements, see Running a Lambda Function as Root.

In an AWS CloudFormation template, RunAs is a property of the Execution property type.
