Give duplicati running in docker root access

How-To
1

Hi, I’m running duplicati in docker using Caprover one click apps (one-click-apps/public/v4/apps/duplicati.yml at master · caprover/one-click-apps · GitHub). I’m trying to backup other docker volumes, but I am running into permission issues, where duplicati can’t access the contents of var/lib/docker/volumes. How do I give it permission to access this folder?

Hi @AhsanSarwar45 welcome to the forum.

This is a bit Docker specific, so I found this SO thread that explains how to grant the permissions.

That uses the linuxserver duplicati image, which uses restrictive PUID and PGID values. You could try changing those to 0, or use the main duplicati docker image instead of linuxserver. The main project image already runs duplicati with root level permissions.

Thanks, setting PUID and PGID to 0 worked.
