Installing K3s on Raspberry Pi Cluster

Description

This article will document how to deploy K3s to a cluster of Raspberry Pis.

Requirements

I am using the following:

This is a self-contained example of both the rendezvous server (UDP brokering) and a fully-asyncio P2P client that:

Uses STUN to detect your NAT type and public mapping (pystun3)
Attempts a permanent UPnP port forward if available (miniupnpc)
Registers with a public rendezvous server over UDP
Performs a simultaneous TCP open (true TCP hole-punch) via asyncio
Falls back to a simple TCP-relay on the rendezvous server if punching fails

You’ll need to install:

Below is a beginner-friendly roadmap you can follow from absolute zero to your first industry-recognized credential. Skim it all once, then work through it one phase at a time.

ft sync on Linux (Debian/Ubuntu)

fieldtheory (ft) is a CLI tool that syncs your X/Twitter bookmarks locally. Its built-in ft sync command reads cookies directly from Chrome — but that feature is macOS-only. On Linux you'll see:

Couldn't connect to your Chrome session.

This script is a drop-in workaround. It extracts the cookies from Chrome or Brave on Linux using the GNOME Secret Service (keyring), then calls fieldtheory's internal sync function directly.
