The docker does not require running as root. The default user is set to root for convenience and to verify upon start up
that all the directories and files have the correct permissions. The user drops to
nobody and group
(65534:65534) before starting Lenses.
If the image is started without root privileges, Lenses will start successfully using the effective uid:gid applied. Make sure any volumes mounted (i.e. for license, settings, data) have the correct permission set.
