Adapting My DrinkMe for Linux Pipulate Script for Macs
I'm adapting my DrinkMe Linux Pipulate Script for Macs, so I'm using a Linux VM on a Mac for the most precise code execution. To make this easy, I'm using Canonical's MultiPass, which turns on virtualization and sets up a working instance of Ubuntu. I'm also using Apple Bonjour's mDNS to map host ports to the VM ports, and I've updated the install script to ensure Linux graphics work in headful mode.
Adapting My Linux Pipulate Script for Macs with MultiPass and mDNS

Given that Debian-based Linux currently has the most users of any Linux distribution (because Microsoft chose it for WSL and Google chose it for ChromeOS), I’m going to treat Debian-based Linux VMs as a universal interoperable layer for executing standard server scripts.
Mac folks may object because Macs are already Unix, and Unix is what Linux itself is based on. Why would you emulate Linux on Unix? Well, the answer is in order to get a precise and error-free code execution environment for running and distributing scripts that don’t need entire Docker containers.

Containers are a way to get a lot of what it seems I’m going after here, except they are somewhat immutable and not easily modified. You can’t just treat a Docker image like a Linux system and modify it as you need. There’s this extra level of complexity called compositing which makes all the normal Linux stuff you’ll be learning down the road far more difficult.
Instead, a local Linux VM is built and modified as you need in ways not so easily accomplished on a Mac or with Docker. The general methodology used here with a Linux VM on a Mac is almost exactly the same as with the Linux VM on Windows, except that Microsoft provides a subsystem for Linux by default, so you can just grab Ubuntu from the Microsoft store.
Macs on the other hand would require a third-party virtualization solution like VirtualBox, Parallels or VMware Fusion. Already things get way more complicated than I’d like them to be for such a simple task. With WSL on Windows you simply get a Linux Terminal at the end of the install process which you can open and use just like an integrated Windows program. You don’t “feel” the Linux virtualization at all, and this is pretty much the same experience I want Mac folks to have. Once again, Canonical, the company that developed Ubuntu to the rescue.
For those learning about these topics for the first time from this article, the Linux distro known as Ubuntu is the most commercial and popular Linux derived from Debian. Debian is the actual root of this branch of the Linux distro lineage. There are other original root distros such as RedHat and Arch. RedHat was the first IBM-supported billion-dollar Linux and Arch is for old schoolers. Ubuntu is the most popular derivative of Debian.
Debian is the one we’re going to use because Microsoft and Google chose it and the Windows install is dirt simple. The Mac install isn’t much worse, except that it has to come from a 3rd party, so there isn’t one clear path to follow. I choose the path provided by Canonical, the company that developed Ubuntu. That path is a custom installer that handles three very tricky bits:
- Turning on true hardware virtualization (Hypervisor)
- Installing the free and open source software (FOSS) VirtualBox
- Installing a working and configured instance of Ubuntu
Ubuntu’s MultiPass product does all that lovely stuff to make this process as easy on Macs as on Windows. I have to think that MutliPass was developed by Canonical to deal with WSL-envy felt by Mac users. A Mac zealot would never admit it, but being forced to use a 3rd party software repo like Homebrew to do formal dev stuff, and Homebrew… let me check…
Mike Levin: is homebrew officially supported by apple?
Bing: Yes, Homebrew is officially supported by Apple. According to a 9to5Mac article¹, Homebrew now officially supports Apple Silicon installations. Homebrew worked on Apple Silicon prior to this announcement, but with some limitations and other issues. Now, Apple Silicon installation is officially supported. The package manager is natively supported for installations in /opt/homebrew²³. However, the team notes that it doesn’t yet provide bottles (binary packages) for all packages².

Mike Levin: Wrong! Homebrew officially supporting Apple silicon is not the same as Apple officially supportingn the Homebrew software repository and formula system. I ask again, does Apple officially support Homebrew? (Not the other way around)
Bing: I apologize for any confusion. According to a coalitionbrewing.com article², Apple does not officially support Homebrew. Homebrew is an open-source package manager and package repository for macOS and Linux. It is designed to build and install software from source, but it can also be used to install pre-built software packages from third-party repositories². However, Homebrew now officially supports Apple Silicon installations¹³.

Mike Levin: Write an essay on the pros and cons of a open-source package manager that is officially supported by the operating system and hardware it runs on, such as the Ubuntu repo on WSL, versus an open-source package manager that is not officially supported, such as Homebrew on Macs.
Bing: An open-source package manager that is officially supported by the operating system and hardware it runs on has several advantages. For example, it is more likely to be stable and reliable because it has been tested and optimized for the specific operating system and hardware. It is also more likely to be secure because it has been vetted by the operating system vendor and has undergone security testing. Additionally, an officially supported package manager is more likely to be updated regularly with new features and bug fixes.
However, there are also some disadvantages to an officially supported package manager. For example, it may not support as many packages as an unofficial package manager because it has to go through a vetting process before being added to the repository. Additionally, an officially supported package manager may not be as flexible as an unofficial package manager because it has to adhere to certain guidelines and standards.
On the other hand, an open-source package manager that is not officially supported has several advantages as well. For example, it may support more packages than an officially supported package manager because it does not have to go through a vetting process before being added to the repository. Additionally, an unofficial package manager may be more flexible than an official package manager because it does not have to adhere to certain guidelines and standards.
However, there are also some disadvantages to an unofficial package manager. For example, it may not be as stable or reliable as an official package manager because it has not been tested and optimized for the specific operating system and hardware. Additionally, an unofficial package manager may not be as secure as an official package manager because it has not undergone security testing.
In conclusion, both officially supported and unofficially supported open-source package managers have their pros and cons. The choice between them depends on the specific needs of the user.
Okay, so there’s pros and cons. I won’t feel too bad about making the DrinkMe script for the Mac Homebrew based. Let’s get to that discussion with Bing:
does multipass run on m1 and m2 macs?
Yes, Multipass runs on both M1 and M2 Macs. The quickest way to run Linux cross-platform, Multipass received an update last year allowing M1 users to run Ubuntu VMs with minimal set-up²³⁴.

Mike Levin: MultiPass is Canonical’s simplified VirtualBox installer and configuration for running virtual Ubuntu on Macs. Some systems like WSL use VLANs and port mapping to make VM services available to the host machine. How does this work with MultiPass? It may not be a VLAN. The networking context for virtualization may be different.
Bing: According to Multipass documentation¹, you can map host ports to VM ports using the same formula. For example, if you want to use the VM as a web server, you can map the host’s 80 and 443 port to the VM. To access the host directory from the guest VM, you will need help from the command multipass mount. It will mount the host folder into the guest VM². I hope this helps!

Mike Levin: Aside from a mapped port, what address or IP should be used in the URL to reach a webserver on a MultiPass VM on a Mac?
Bing: You can use the IP address of the Multipass instance to access the webserver running inside it. To find out the IP address of your Multipass instance, you can use multipass info <instance-name> command¹. Once you have the IP address, you can use it in your URL to access the webserver running inside your Multipass instance². I hope this helps!

The name of the interface used when --bridged is issued is local.bridged-network². In bridged networking mode, the guest machine is like another physical machine on the network and is exposed to your local network³. You can use the IP address of your Multipass instance to access the webserver running inside it. You can also use localhost or 127.0.0.1 to access the webserver running inside your Multipass instance¹. I hope this helps!

Mike Levin: Write a Unix shell script that will install MultiPass in a Intel, M1 or M2 Mac, and which will allow a website hosted on the VM to be accessible to the host machine on port 8888.
Bing: I can help you with that. Do you have any specific version of Multipass that you want to install? Also, do you have any specific website in mind that you want to host on the VM?
The website will be JupyterLab server installed with a pip install Jupyter. I need a MultiPass that will work (or adapt) to all modern Mac hardware architectures.
Here’s a shell script that will install Multipass and JupyterLab server on your Mac. This script should work on all modern Mac hardware architectures.
#!/bin/bash
# Install Multipass
brew install multipass
# Launch an instance with bridged networking
multipass launch --name jupyterlab --cpus 2 --mem 4G --disk 10G --cloud-init cloud-config.yaml --network local.bridged-network
# Install JupyterLab server
multipass exec jupyterlab -- sudo apt-get update
multipass exec jupyterlab -- sudo apt-get install python3-pip -y
multipass exec jupyterlab -- sudo pip3 install jupyterlab
# Forward port 8888 to the host machine
multipass exec jupyterlab -- jupyter lab --ip=0.0.0.0 --port=8888 &
multipass transfer jupyterlab:/home/ubuntu/.local/share/jupyter/runtime/nbserver-*.json .
echo "JupyterLab server is running at http://localhost:8888"
This script will launch an instance named jupyterlab with 2 CPUs, 4GB of memory, and 10GB of disk space. It will also install JupyterLab server and forward port 8888 to the host machine so that you can access the JupyterLab server at http://localhost:8888. You can save this script to a file named install.sh and run it in your terminal by typing sh install.sh. I hope this helps!

And there you have it. I’ll implement this real soon if you’re a Mac user following along with my work and are feeling Windows Linux Envy (you heard it here first). The Dev Revolution (devrev?) is taking place on Linux, everything from interoperable local scripts like this to supercomputers, AI, Mars probes, and well everything else. It’s not on proprietary Windows nor proprietary Mac. Yes, Macs are still proprietary even though they’re Unix based. And according to these strict definitions, even Ubuntu is a bit proprietary, but in less long-term damaging to your dev-skills and generic tech know-how than Macs are.
Debian-derivative Linux VMs are the least worst evil. They abide by the 80/20-rule in getting the most powerful, least fragile, most persistent and transferable valuable tech knowledge, yadda, yadda, already said it.
