Support for systemd-resolve #32

Open smihael opened 3 years ago

smihael commented 3 years ago

This image uses systemd-networkd to regenerate the host's /etc/resolv.conf. However, on Ubuntu 20.04-based systems resolv.conf is linked to ../run/systemd/resolve/stub-resolv.conf which hints to the use of systemd-resolve service.

This causes error as/tmp/systemd/network is not present.

$ docker run  --hostname resolvable -v /var/run/docker.sock:/tmp/docker.sock -v /run/systemd:/tmp/systemd   -v /var/run/dbus/system_bus_socket:/var/run/dbus/system_bus_socket  mgood/resolvable
