Set up persistent storage for K3s (via USB drive)

Get root: ssh pi-k3s-master.local -t sudo su
Find your disk via fdisk -l (e.g. /dev/sda1)
Erase drive by repartitioning: mkfs.ext4 /dev/sda1

Mount drive:

mkdir /mnt/pi-k3s-storage
chown -R ericboehs:ericboehs /mnt/pi-k3s-storage
mount /dev/sda1 /mnt/pi-k3s-storage

Chromium on Vercel (serverless)

This is an up-to-date guide on running Chromium in Vercel serverless functions in 2022. What you will read below is the result of two days of research, debugging, 100+ failed deployments, and a little bit of stress.

Getting started

Step 1: Install dependencies

Use chrome-aws-lambda that comes with Chromium pre-configured to run in serverless, and puppeteer-core due to the smaller size of Chromium distributive.
