Download Pi OS lite version from https://www.raspberrypi.com/software/operating-systems/
unxz the image and use dd to write it to a SD card.
Mount the SD card / and /boot on a directory under /mnt/, eg.
sudo mkdir -p /mnt/d1/boot /mnt/d1/root sudo mount /dev/mmcblk0p1 /mnt/d1/boot sudo mount /dev/mmcblk0p2 /mnt/d1/root
Run the ./setup.sh script, passing /mnt/d1/
sudo ./setup.sh /mnt/d1/
Edit /mnt/d1/boot/wpa_supplicant.conf and change the SSID and password to your AP.
Optionally change the password of the life user by replacing the default password in /mnt/d1/boot/userconf with the output from: openssl passwd -6
Unmount /mnt/d1/boot and /mnt/d1/root and insert the SD card into the Pi and boot it.
It is best to do this with a display and keyboard so you can see what IP address is assigned, or deal with any unexpected errors.
Now you can reboot, and it should show the IP address at the login prompt, depending on the timing of bringing up the network.
Edit the hosts file to set the correct IP address. Run the setup.yml playbook to setup the life display and change the boot display settings.
ansible-playbook -v -k ./setup.yml
the SSH password will be the password you created for the 'life' user. Or the default of asdasdasd
It is easiest to just build the sdl2-life program on the Pi. The git repo has been checked out into /opt/sdl2-life/ and it should simply be a matter of running:
cd /opt/sdl2-life && go build
to build it.
At this point the system should be ready. You can run /home/life/run-life-server to test, and then reboot to make sure it starts on its own.
If everything looks ok you can turn off the boot logo and text by editing /boot/cmdline.txt and adding:
logo.nologo console=null quiet
to the end of the kernel boot cmdline. This does make it much harder to debug problems, but worst case you can mount the SD card on another system and remove those arguments to turn them back on.
