Rebuild Raspbery PI - Winter 2023/2024 Edition

[scottmuc]

Yay for Repaving!

As much as possible is documented inline in this issue template. In case of problems you may find help by viewing all the previous repave issues. Have fun!

Things to do with the existing build

• [x] Enable DHCP on the router, remove port mapping and statically assign network to PC

  Instructions

  Insert screenshots here ;-)

• [x] Shutdown PI

  Instructions

  Make sure the USB drive has spun down before doing any work.

  sudo shutdown -h now

• [x] Create SD card with the latest Raspberry Pi OS

  Instructions

  Using the SD card in the now powered down PI.

  The new installer has options to enable SSH and create a user.

  installer download

  note check if the underlying Debian distribution is changing as this might result in some issues in the playbook execution.

  The Bullseye 64-bit lite image seems to work for now.

Post OS install steps on desktop

• [x] Ensure a working ansible enviroment

  Instructions

  This will exercise the asdf setup.

• [x] Turn on the PI and note the IP obtained from the Router

• [x] Clean up old host keys

  Instructions

  The new instance will have new host keys so to ensure host key warning messages don't distract us from the repaving, run the following:

  ssh-keygen -R 192.168.2.10
  ssh-keygen -R pi
  ssh-keygen -R pi.home.scottmuc.com
  ssh-keygen -R 192.168.2.102

• [x] Transfer local public ssh key to PI

  Instructions

  In order to avoid the use of sshpass, copy the current sessions public ssh key to to ./ssh/authorized_keys of the pi user on the PI. This user is only necessary to run the bootstrap playbook (which creates an admin ansible user) and will be subsequently cleaned up.

  ssh-copy-id pi@<pi ip>

• [x] Bootstrap with Ansible

  Instructions

  ./ansible.sh and select the bootstrap-playbook.yml

• [x] Add the PI port forwarding

  Instructions

  Needed for the certbot ACME challenge in the next step.

• [x] Complete full configuration

  Instructions

  ./ansible.sh and select the main-playbook.yml

• [x] Reboot PI

• [x] Re-add port mapping to the static IP

• [x] Disable DHCP on the router

• [x] Deploy goodenoughmoney.com

• [x] Create pi Samba user

  Instructions

  Run the following on the PI sudo smbpasswd -a smbrw

• [x] Make this template slightly better

How Do I Know I Am Done?

• [x] https://www.goodenoughmoney.com/ displays stuff

• [x] https://home.scottmuc.com/music/ loads navidrome and the music is playable

• [x] http://prometheus.home.scottmuc.com:9090/ loads and has data

• [x] http://grafana.home.scottmuc.com:3000/ loads and has data

• [x] Z:\ on my Windows PC works

• [x] ipconfig /release and then ipconfig /renew works

• [x] nslookup analytics.google.com is refused

• [x] Print out newly repaved machine details

  Instructions

  cat /etc/os-release && uname -a

Raspberry Pi Imager upgraded from 1.7.6 -> 1.8.4. The new UI was a bit confusing as it was trying to help. It asked what device I am using so it would filter the OSes accordingly... but when I selected a PI 3 it filtered out the 64bit Bookworm OS I have been running.

• [x] update imaging help to reflect new reality.

[scottmuc]

Both ansible playbook runs ran without an issue!

Repave Summary

This was probably as smooth as it gets. Probably as fast as it gets too. So 60min is the relative floor for how long it takes to repave the Pi. This was also done without recording or pairing so there weren't really any moments to reflect and explain.
