Download Raspbian Lite and flash it to an SD card and all USBs.

Default user is pi, password is raspberry.

On a first RPI boot from SD card and upgrade all:

sudo apt-get install && sudo apt-get upgrade

Add the following line to the end of /boot/config.txt

program_usb_boot_mode=1

WARN Don't create any new lines.

Reboot device and validate that USB boot is enabled:

$ vcgencmd otp_dump | grep 17
17:3020000a

Boot from this SD card all others RPis. At this point you can start booting from a USB sticks.

On every node you need to setup static IP in /etc/dhcpcd.conf (use your network):

profile static_wlan0
static ip_address=192.168.0.101/24
static routers=192.168.0.1
static domain_name_servers=8.8.8.8

You may choose to setup static IPs through your router.

Then setup through raspi-config:

• WiFi connection
• Host name, e.g. k8s-master-1, k8s-worker-1, k8s-worker-2, etc.
• Change pi password
• Enable sshd server

Last but not least is to enable ntp which will sync clocks between your workers. This is extremely important since server will drop too old messages.

ntp is disabled by default in the latest system versions.

 sudo apt install ntp
 sudo systemctl enable ntp
 sudo timedatectl set-ntp 1

To adjust your timezone run raspi-config and go to Localization Options -> Change Timezone.
