docker-vagrant: Seamless Docker VM Provisioning for macOS

This Docker CLI plugin lets you manage a Vagrant-powered Docker host directly from the Docker CLI. The current implementation uses Parallels Desktop, but feel free to adapt my Vagrantfile to other Hypervisors -- the user interface will be the same.

Why?

Docker on macOS can be tricky — Docker Desktop comes with licensing concerns, performance issues, and hidden magic. This plugin lets you:

✅ Provision a dedicated Linux VM with your perfect Docker setup.

✅ Seamlessly switch your Docker CLI to use the VM via Docker Contexts.

✅ Manage the VM directly through Docker CLI: docker vagrant up, docker vagrant ssh, etc.

Install

Clone this repository and run make install in the project directory. This will create a new Docker CLI subcommand docker vagrant that manages the Docker virtual machine.

Usage

Works just like Vagrant, but scoped to Docker:

docker vagrant up          # Start the VM and configure Docker context
docker vagrant ssh         # SSH into the VM (you will rarely need this)
docker vagrant suspend     # Pause the VM
docker vagrant resume      # Unpause the VM
docker vagrant halt        # Stop the VM
docker vagrant destroy     # Remove the VM

All commands will automatically set up or tear down an appropriate Docker context, so you can immediately use docker:

$ docker vagrant up
Bringing machine 'default' up with 'parallels' provider...
... lots of output ...
$ docker context ls
NAME                 DESCRIPTION   DOCKER ENDPOINT
docker-parallels *   dockerhost    tcp://10.211.55.91:2376
$ docker run -it --rm alpine
/ # 

Prerequisites

• Parallels Desktop for Mac (Pro edition)
• Docker CLI on your Mac
• Vagrant
• The Parallels provider for Vagrant

  brew install docker vagrant
  vagrant plugin install vagrant-parallels

Details

• docker vagrant up will provision a new VM based on bento/ubuntu-24.04, installs an up-to-date Docker daemon, generates TLS certificates and creates a new Docker context named docker-parallels on your Mac, that is activated automatically.

• implementation: the VM is provisioned by provision.sh; adding the Docker context to the Mac is done by host.sh. Both scripts are automatically run by Vagrant for all lifecycle commands.

• The VM is provisioned to share /Users with the Mac; this makes it easy to add volumes from home directories to Docker containers using the same paths as on the Mac:

  docker run -it -v `pwd`:`pwd` alpine

• Parallels will automatically add the VM to /etc/hosts on the Mac under the name dockerhost; thus servers in Docker containers can be reached from the Mac as dockerhost:<port>, e.g. this container:

  docker run -p 8080:80 nginx

  ... would be here http://dockerhost:8080

• Bug 2025-02-01 Parallels 20.2 discontinues the prl_fs fstype. Update the vagrant-parallels plugin to at least version 2.4.4 for a workaround that uses prlfsd and FUSE instead.

Feel free to hack on the scripts and drop me a MR.
