Docker User Setup Security

Hey all, just a quick post, If you have read any of my guides you will see I always grant access to my Synology shares using the admin group ID and a my admin account user ID.

Thanks to a Reddit userย /u/jasonsteelj that pointed out this is not very good practice if a container is compromised it has admin rights to all your shares.

In order to limit this you should setup a unique user for each container limiting its access to only the data it should.

So over the next few days I will be updating the guides to show how this is done, as well as updating my own personal containers.

    A guide to better security is always good.

    Sometime I am just happy to get things running, that I brush under the carpet anything that may break something.

      True, I never really thought of this element when I set out.

    Dear Dr. F,

    The link to your SABNZBD tutorial is gone ๐Ÿ™

    Would you be so kind to restore it?

    Thank you very much,

    Bye from The Netherlands,

      Hey Vince, I need to edit it as the pictures are broken, i will re-enable with a note for you until I get chance to edit it

    Hi Doc ๐Ÿ˜€

    Thanks for your reply. I managed to get it working anyway. However: I think there is something not working: the PUID and PGID.

    Because: suppose you create a user docker-sabnzbd, PUID=1060, PGID=100.

    If you put these two in the environmental settings, restart the container, and then go to the CLI via SSH and issue ps -u | grep sab (to display the process running concerning sabnzbd), you will see that the process is still run as root, not as the user docker-sabnzbd.

    You may try that for yourself.

      Hey, do you mean the SAB user within the container itself? As the user within the container may be a root, but it will only have access as per the user rights you have given PUID 1060 on the host. That’s how I understood it.

    Hi Doc,

    I don’t know of any SAB user in the container itself?

    The ps -u | grep sab shows the container runs as root, not as PUID 1060.

    Your IP via a ping is:

      This site is hosted on an OVH shared server so it’s their IP

  6. A Jackett setup guide would be great too! ๐Ÿ™‚ Thanks for all your help

      This is one I will add to the list

    Could you provide a walk-through for setting up rclone through Docker to stream movies to Plex from Google Drive? Even a guide for setting up rclone without Plex integration would be extremely useful.

      You wont catch me uploading anything to Google Drive especially copyrighted content. Not something I would use I am afraid.
