Context: Docker bypasses all UFW firewall rules
(lemmy.world)
Docker docs:
Docker routes container traffic in the nat table, which means that packets are diverted before it reaches the INPUT and OUTPUT chains that ufw uses. Packets are routed before the firewall rules can be applied, effectively ignoring your firewall configuration.
I've been playing with systemd-nspawn for my containers recently, and I've been enjoying it!
Try podman and quadlets
Quadlets are so good.
What advantage does it have over nspawn?
