Lan Ip And lxdbr0 Ip

2

Hi Najib!

You can create a LXD profile with two entries about networking (macvlan, and bridged), then create a container using that profile.
Here is how to do that:

  1. I suppose you already have a profile according to https://blog.simos.info/how-to-make-your-lxd-container-get-ip-addresses-from-your-lan/ Let’s call that profile lanprofile.

  2. Copy that profile into a new name, let’s say, macbridge (macvlan and bridge).

    lxc profile copy lanprofile macbridge

  3. Add a new eth1 network interface for the lxdbr0 bridge.

    lxc profile device add macbridge eth1 nic nictype=bridged parent=lxdbr0

  4. By doing so, the macbridge profile will look like:

    devices:
  eth0:
    nictype: macvlan
    parent: enp3s0
    type: nic
eth1:
  nictype: bridged
  parent: lxdbr0
  type: nic

  5. And now you can launch the container with

    lxc launch ubuntu:18.04 --profile macbridge mycontainer

When you get a shell in mycontainer, you will notice that eth1 did not get an IP address automatically. It’s up to you to make the configuration to get the IP address automatically. The manual way, anyway, is sudo dhclient eth1.
