important

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

Set up DNS with Dnsmasq

important

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.

   bind-interfaces

   # The line below comes from the domain you want to use and what ip you want to point it to

   address=/.onepanel.test/192.168.99.0

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 127.0.0.53 nameserver.

nameserver 127.0.0.53

Make sure the changes persist

sudo resolvconf --enable-updates

sudo resolvconf -u

Finally, reboot your machine.
