Nomad, WSL and bridge networking

Hi all,

I’m running the vanilla ubuntu nomad from the online tutorial and I’m running into network issue.

Specifically, docker backed services gets bound to the 127.0.0.1 IP, which makes them un-accessible from other service containers.

As mentioned in other posts (Nomad service address resolves to localhost ) , I’ve tried using the bridge network type with the address_mode = alloc setting, but no joy.

I think I traced it down to the fact that the bridge network mode gets disabled in nomad due to:

   2023-05-24T13:10:35.636+0100 [WARN]  client.fingerprint_mgr: failed to detect bridge kernel module, bridge network mode disabled:

On a side node, bridge networks work just fine using docker-compose, so I assume nomad’s bridge network is something more general as it covers more than just docker containers.

Is there a way to setup nomad so it activates bridge networking on WSL?

Thanks!
