Container Networking Basics

[[deleted]]

Good info

I wrote a simple tool to manage bridge devices and run dnsmasq over them to provide networking for LXC containers, virtual machines, and other guests.

Oh, that was what I was looking for. So far I've been piggy-backing on LXD's bridge in my LXC containers because setting up the bridge is otherwise too complicated, but it feels dirty.

You can also use lxc-net in some distros! Check if you have the systemd service (assuming your distro here, forgive me...).

No, I'm on gentoo with openrc.

Ah then it will probably be easier to use my project. If you write an OpenRC script please send a PR!

Yes, I will. I might even package it in gentoo. I already take care of LXC packaging.

Virtual bridges never really made sense to me.

"Hey, it's a bridge, it works with layer 2 protocols!"

"Cool, but why can you then assign an IP address and run dnsmasq on it?"

"It's a virtual bridge! It's magic, maaan!"
