Automating UTM VMs on macOS

A comprehensive, distribution-agnostic guide to automating VM creation and management with UTM on macOS.

Document Information

Abstract: This guide documents hard-won lessons from real-world UTM automation, focusing on the challenges unique to UTM/QEMU on macOS rather than any specific Linux distribution.

Claude Jail DevContainer

This is a Taskfile that would start claude in an isolated Docker container in the "unhinghed" node with --dangerously-skip-permissions.

Creates:

rename a section of a filename, i. e. example.1.{txt,conf,db} or 12345.1.{wav,ogg,mp3} and change the 1 to a 2 in the filename while preserving the rest of it.

  zmv -n '(*.)(<->)(.[^.]#)' '$1$(($2+1))$3' # would rename x.0001.y to x.2.y.
  zmv -n '(*.0#)(<->)(.[^.]#)' '$1$(($2+1))$3'

Rename files to lower case

  $ zmv '*' '${(L)f}'

Safest way to clean up boot partition - Ubuntu 14.04LTS-x64, Ubuntu 16.04LTS-x64

Reference

Case I: if /boot is not 100% full and apt is working

1. Check the current kernel version

$ uname -r

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

	FROM debian:10-slim

	RUN apt-get update -y && \
	apt-get install -y awscli curl gnupg && \
	apt-key adv --fetch-keys "https://nginx.org/keys/nginx_signing.key" && \
	echo "deb http://nginx.org/packages/debian buster nginx" > /etc/apt/sources.list.d/nginx.list

	RUN curl --silent --show-error --location --output /tmp/amazon-ssm-agent.deb "https://s3.us-east-1.amazonaws.com/amazon-ssm-us-east-1/latest/debian_amd64/amazon-ssm-agent.deb" && \
	dpkg -i /tmp/amazon-ssm-agent.deb

	on run {input, parameters}
	tell application "Finder"
	set my_file to first item of input
	set is_folder to (do shell script "file -b " & quoted form of (POSIX path of my_file))
	if is_folder ends with "directory" then

	#include <Servo.h>

	Servo myservo;

	const int servoPin = 9;
	const int buttonPin = 12;
	const int ledPin = 13;

	void setup() {
	myservo.attach(servoPin);

	#!/bin/sh

	# Replace chat_id value with your chat id from @myidbot
