A UID (user identifier) is a number assigned by the Asustor NAS ADM operating system to each user on the system. This number is used to identify the user to the system and to determine which system resources the user can access. Groups in Asustor NAS ADM are defined by GID (group ID). These values often dictate the user/group that the Docker container will be running as. So if the Docker container accesses a specific drive share, with specific permissions, then the PUID and PGID values will specify the user/group that will be used by the Docker container.
