Bug: can't use docker because error while starting network service: 'no such file or directory' #910
Description
Hi,
Very happy with edgevpn for a while now. But I stumbled upon the Dockerfile and thought it would be better for my use case.
And well besides #908 , I was never able to make it work.
I tried disabling dht, dhcp, using the host network mode and a bunch of other things, to no avail.
Then I noticed that if I ran edgevpn api/start/service-add/etc it seemed to work. Only without those would it crash. Also adding --dhcp seemed to not make it crash.
Here is the reproduction code:
sudo docker run -it --env "EDGEVPNTOKEN=$(edgevpn -g -b)" --rm quay.io/mudler/edgevpn:latest

error while starting network service: 'no such file or directory'
This seems to be the same bug as #44
Edit: I was able to fix it: I needed to expose a device to docker compose:
devices:
- /dev/net/tun:/dev/net/tunI will make a PR to explain how to use docker compose to setup edgevpn
