ReYuki realyukii

start the program in background

setsid ngrok tcp <port> &>/dev/null </dev/null

optional, if you want store the log, enable ngrok option --log=stdout

parse the json string with node

node -pe 'JSON.parse(process.argv[1])' $(curl -s http://localhost:4040/api/tunnels)
# atau

The idea came from Nir Lichtman video with the title: 'Making Simple Linux Distro from Scratch'

this gist just re-document it in the form of text

Requirement

compiled linux kernel
compiled static-linked busybox
installed qemu

Creating initramfs

Live Boot arch linux:

qemu-system-x86_64 \
-drive format=raw,file=./archlinux-2024.04.01-x86_64.iso,index=0,media=disk \
-enable-kvm -machine pc -cpu host -m 1G -nographic

Since the above command using -nographic, so we don't start VNC server, thus don't forget to add console=ttyS0 to kernel parameter, press on the bootloader to modify kernel parameter
