Lightweight Alpine VMs on MacOS

Create and manage lightweight Alpine VMs on MacOS with:

🔁 Seamless port forwarding

🗂️ Automatic file sharing

🎢 Bridged networking

🚀 aarch64 and x86_64 emulation

Motivation

The goal of this project is to enable MacOS users to:

Easily spin up and manage lightweight Alpine Linux environments.
Use tiny VMs to take advantage of containerisation technologies, including LXD and Docker.
Build and test software on x86_64 and aarch64 systems.

Installation

Macpine depends on QEMU >= 6.2.0_1:

#brew update
#brew upgrade
brew install qemu

Install the latest binary

Download the latest binary release for your system and add it to your path by placing to e.g. /usr/local/bin/:

wget https://github.com/beringresearch/macpine/releases/download/v0.8/alpine_darwin_arm64
mv alpine_darwin_arm64 alpine
sudo chmod +x alpine
sudo mv alpine /usr/local/bin/

Install from Homebrew

brew install macpine

Install from MacPorts

On macOS, you can install via MacPorts:

sudo port install macpine

See more information here.

Install from source

git clone https://github.com/beringresearch/macpine
cd macpine
make

Getting Started

To launch a brand new VM:

alpine launch #launches with default parameters
alpine launch -a aarch64 #create an aarch64 instance
alpine launch -d 10G -c 4 -m 2048 #create a machine with a 10GB disk, 4 cpus and 2GB of RAM

Access VM via ssh:

alpine launch -s 22 #launch a VM and expose SSH port to host port 22
ssh root@localhost -p 22 #password: root
alpine ssh $VMNAME #attach to the VM shell

Expose additional VM ports to host:

alpine launch -s 23 -p 8888,5432 #launch a VM, expose SSH to host port 23 and forward VM ports 8888 and 5432 to host ports 8888 and 5432

VMs can be easily packaged for export and re-use as tar.gz files:

alpine list

NAME                STATUS      SSH    PORTS ARCH        PID 
forthright-hook     Running     23           aarch64     91598
hot-cow             Running     22           x86_64      82361

alpine publish hot-cow

This will create a file hot-cow.tar.gz which can be imported as:

alpine import hot-cow.tar.gz
