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.
For all the raving about podman, it's dumb too. I've seen multiple container networks stupidly route traffic across each other when they shouldn't. Yay services kept running, but it defeats the purpose. Networking should be so hard that it doesn't work unless it is configured correctly.
Or maybe it should be easy to configure correctly?
instructions unclear, now its hard to use and to configure
That's asking a lot, these days.
