  • The issue is that the docker container will still be running as the LXC’s root user even if you specify another user to run as in the docker compose file or run command, and if root doesn’t have access to the dir the container will always fail.

    The solution to this is to remap the unprivileged LXC’s root user to a user on the Proxmox host that has access to the dir using the LXC’s config file, mount the container’s filesystem using pct mount, and then chown everything in the container owned by the default root mapped user (100000).

    These are the commands I use for this:

    find /var/lib/lxc/xxx/rootfs -user 100000 -type f -exec chown username {} +;
    find /var/lib/lxc/xxx/rootfs -user 100000 -type d -exec chown username {} +;
    find /var/lib/lxc/xxx/rootfs -user 100000 -type l -exec chown -h username {} +;
    find /var/lib/lxc/xxx/rootfs -group 100000 -type f -exec chown :username {} +;
    find /var/lib/lxc/xxx/rootfs -group 100000 -type d -exec chown :username {} +;
    find /var/lib/lxc/xxx/rootfs -group 100000 -type l -exec chown -h :username {} +
    

    (Replace xxx with the LXC number and username with the host user/UID)

    If group permissions are involved you’ll also have to map those groups in the LXC config, create them in the LXC with the corresponding GIDs, add them as supplementary groups to the root user in the LXC, and then add them to the docker compose yaml using group_add.

    It’s super confusing and annoying but this is the workflow I’m using now to avoid having to have any resources tied up in VMs unnecessarily.








  • You’d be surprised how often none of that is touched, and I really doubt any repackers are bothering to block any network calls if the original scene release didn’t. I’ve used some equivalent of OpenSnitch that prompts on all network requests that I haven’t explicitly allowed already for the past decade, and at least 90% of all games I downloaded during that time tried to phone home.

    ALWAYS set firewall rules to block internet access to any software you pirate.








  • I only use rolling releases on my desktop and have ran into enough issues with apps not working because of changes made in library updates that I’d rather they just include whatever version they’re targeting at this point. Sure, that might mean they’re using a less secure version, and they’re less incentivized to stay on the latest version and fix those issues as they arise, but I’m also not as concerned about the security implications of that because everything is running as my unprivileged user and confined to the flatpak.

    I’d rather have a less secure flatpak then need to downgrade a library to make one app I need work and then have a less secure system overall.




  • IIRC from running into this same issue, this won’t work the way you have the volume bind mounts set up because it will treat the movies and downloads directories as two separate file systems, which hardlinks don’t work across.

    If you bind mounted /media/HDD1:/media/HDD1 it should work, but then the container will have access to the entire drive. You might be able to get around that by running the container as a different user and only giving that user access to those two directories, but docker is also really inconsistent about that in my experience.
