Chef bootstrap for Raspberry Pi

Chef bootstrap for Raspberry Pi

This project creates an auto-updating chef-zero based Raspberry Pi node.

1. Write a Debian-based image to the SD card for your Pi (I advise the Buster Lite image as a good small base)
2. SSH into the node (possibly just ssh pi@raspberrypi with password "raspberry" if you're using the defaults)
3. wget https://raw.githubusercontent.com/palfrey/raspberry-chef/master/bootstrap.sh
4. cat bootstrap.sh

• Read the contents of bootstrap.sh and make sure you understand it before just randomly running something I told you to.

5. sudo bash bootstrap.sh
6. sudo poweroff

You've now got an auto-updating SD card, which you can backup and re-use for other nodes. To configure it, there's a series of files in /boot which is a FAT32 partition, which means it'll get mounted on Linux, OS X or Windows which means you can configure it without having a working Pi.

The following files in /boot are of particular use:

• wifi.conf - a wpa_supplicant configuration file. For simple configs, the changes should be obvious, but for more complicated settings see the example config
• chef-url - a git URL to clone that contains Chef cookbooks
• chef-cookbook - Chef cookbook from the chef-url path to run with chef-client
• chef-directory - Optional subdirectory of the git repo to run chef commands from

The update_chef daemon will automatically check chef-url/chef-cookbook and run chef-client in chef-zero configuration if it finds a valid set of configuration.

chef-utils version issues

Seeing build failures due to more recent chef-utils versions not supporting ruby 2.6. Unfortunately the gem_package bits seem to ignore when I specify locked down versions of it.

`<main>': undefined method `include_path' for Libyajl2:Module

Trying to get this working on my RPI2 B on buster lite. Any ideas what is wrong?

Thanks in advance.
