NixOS in LXC works great, although I switched to bare metal NixOS a few months ago. I didn’t see the need for proxmox as it hindered my ability of declaring the whole system.

Creating NixOS LXC’s is a bit of a pita. Some links that helped me two years ago:

• https://wiki.nixos.org/wiki/Proxmox_Virtual_Environment#LXC
• https://web.archive.org/web/20230818134729/https://blog.xirion.net/posts/nixos-proxmox-lxc/

It’s great to see another open source OIDC provider (with more features). I’ve set up Pocket ID which is awesome because of it’s simplicity and it’s great.

Yes. 127.0.0.0 is the localhost. This is the IP the container is listening on. Even if there was no firewall it wouldn’t allow any connection except from the host. If it’s set to 0.0.0.0 it means it’ll allow connections from any IP (which might not be an issue depending on your setup).

The reverse proxy runs on localhost anyway, so any other IPs have no reason to ever have access.

Some I haven’t yet found in this thread:

• rootless podman
• container port mapping to localhost (e.g. 127.0.0.1:8080:8080)
• systemd services with many of its sandboxing features (PrivateTmp, …)

I do think the second part of your statement was unnecessary.
