posixUser

The POSIX system user and, optionally, group to use to run this component on Linux core devices. The user, and group if specified, must exist on each Linux core device. Specify the user and group separated by a colon (:) in the following format: user:group. The group is optional. If you don't specify a group, the IoT Greengrass Core software uses the primary user for the group.

If you omit this parameter, the IoT Greengrass Core software uses the default system user and group that you configure on the Greengrass nucleus component. For more information, see Configure the user and group that run components.
