Ubuntu 17.04 systemd-resolved configuration

Question

I use Ubuntu for development. And I've build my dev env with using dnsmasq for resolving my dev hostnames, usually it's:

<projectname>.dev.net

So I set up my own DNS server for getting proper IP address (I'm using docker)

I used to create conf file in /etc/NetworkManager/dnsmasq.d with content:

server=/dev.net/172.18.0.1

Thus dnsmasq redirects all dns-resolve request to 172.18.0.1 for *.dev.net domains.

How can I configure the same behaviour for resolved?

Answer 1

It is not possible to configure different upstream servers for i.e. dev.net with systemd-resolved.service

What worked for me (on Ubuntu 17.04) is to install and configure a dnsmasq server alongside the systemd-resolved.service

The steps needed would be:

package installation:

apt install dnsmasq -y

start and enable dnsmasq service:

systemctl start dnsmasq
systemctl enable dnsmasq

add a configuration file inside /etc/dnsmasq.d/ like this:

server=/dev.net/172.18.0.1

Answer 2

Ok, so here is how I resolved this:

First, installed dnsmasq:

sudo apt-get install dnsmasq

added dns=dnsmasq to /etc/NetworkManager/NetworkManager.conf's [main] section.

Edited /etc/systemd/resolved.conf to add:

DNS=127.0.1.1
FallbackDNS=127.0.1.1

in the [Resolve] section.

Copy all needed configuration to /etc/NetworkManager/dnsmasq.d/.

After reboot everything should be fine (or just restart NetworkManager & systemd-resolved).
