Local DNS with Dnsmasq


This guide is for Ubuntu 20.04 or higher installed as host OS on a local cluster.

Set up DNS with Dnsmasq


Make sure you have an ip address and the domain you want to use ready.

  1. We're going to be using dnsmasq so we can use wildcards.

    First, install dnsmasq

    sudo apt install dnsmasq
  2. Now let's update the DNS configuration

    edit the file /etc/dnsmasq.conf

    and add to the end

    # This option is also commented above in the file, but we add it to the end for ease of use.
    # The line below comes from the domain you want to use and what ip you want to point it to
  3. Restart dnsmasq

    sudo systemctl restart dnsmasq
  4. Make dnsmasq dns server reachable

    First, install and enable resolvconf

    sudo apt-get install resolvconf
    sudo systemctl enable resolvconf
    sudo systemctl start resolvconf

Then, edit the /etc/resolvconf/resolv.conf.d/tail file to make sure we keep the nameserver.


Make sure the changes persist

sudo resolvconf --enable-updates
sudo resolvconf -u

Finally, reboot your machine.
