  == Power up and add DNS
  
  You can now power up the first Pi. By default to login use root/hypriot. You will need to set up DNS for each of the Pi's. If you don't want to hook up a monitor and keyboard to login at the console to figure out its IP and Mac address, then you can use nmap [3] to figure this out. If you have a DNS service provision it there, or else name the Pi's in /etc/hosts. I named my Pi's _rpi-master_, _rpi-node-1_, _rpi-node-2_ and _rpi-node-3_. With a quick reboot of each Pi you will see the names reflected at the cmd prompt. Note that if you skip the DNS step your Kubernetes cluster will not work. I added the following to my _/etc/hosts_ files on all machines

  192.168.1.9     rpi-master
  192.168.1.21    rpi-node-1
