At the time of writing, the only viable option to have a decent performance and a good DX are:

  1. VirtioFS to share the filesystem (Docker DesktopRancher DesktopColima) – There are still some issues.
  2. Use named volumes and if you use VSCode you can rely on things like DevContainers to have a good DX – 🚀 BONUSPoC project with Backstage and DevContainers.
  3. Use DDEV + Mutagen for PHP projects (JS coming soon).
  4. If you are VI/Emacs user, all you need is your editor and tools in a container, or if you want a minimal Linux GUI env, take some inspiration here.

How does Docker work on macOS? 

Docker architecture on macOS - Source

Docker engine, on macOS and Windows, needs a Linux Kernel; there aren’t any exceptions here, you do not see it, but it is there to do all the dirty jobs (HN:

Instead, Docker CLI and docker-compose are native binaries for all operating systems.

Two things are worth mentioning here regarding Microsoft; the first one is that Windows (and this sometimes can lead to some confusion) natively support Docker to run Windows containers.

This implementation has been possible thanks to the joint effort of Microsoft and Docker in 2016 to create a container engine implementing the Docker specification on Windows; kudos to you, MS.

The second one is that Microsoft tried in the past to natively support Linux processes by real-time converting syscalls to run unmodified Linux processes on the Windows kernel (WSL1).

You can find here a very detailed deep dive into this brilliant technology; even though Microsoft still supports it, it has significant limitations in terms of performance and compatibility. This is why Microsoft released a new engine, WSL2, which is based on a more traditional approach of a lightweight virtual machine running an unmodified Linux kernel plus some kernel modules to better integrate on Windows.

Anyway, let’s go back to the topic.

Docker for Mac is the official Docker inc. product made to run most seamlessly Docker containers on macOS; they even support Kubernetes.

Some notable features of Docker for Mac:

There are two valid OSS alternatives:

They both use Lima, filesystem-sharing issues are tracked here, and VirtioFS has just landed. It is interesting to see that the consensus around VirtioFS is confirmed, and once again, open source sets the rules.

So, to sum up:

  1. Docker containers are still Linux processes and need a Virtual Machine to run on other operating systems.
  2. Docker-cli and docker-compose are native binaries.
  3. As Docker runs in a virtual machine, something to share the host filesystem with the VM is required; we can choose between OSXFS (proprietary and deprecated), gRCP FUSE, or VirtioFS. They all come with issues, and VirtioFS is the most promising one.
  4. To run Docker containers on Mac, you can choose between Docker for Mac (closed-source), Rancher Desktop (OSS), and Colima (OSS).

What is a Docker volume? 

Now that we know how the underlying things work, we can quickly dive into another confusion-leading topic: Docker Volumes.

Docker containers are ephemeral, and this means that files exist inside the containers as long as the container exists, let’s see a an example:

 1➜  ~ # Run a container and keep it running for 300 seconds.
 3➜  ~ docker run -d --name ephemeral busybox sh -c "sleep 300"
 6➜  ~ # Inspect a container to find the host PID.
 7➜  ~ docker inspect --format '{{ .State.Pid }}' d0b02322a9eef184ab00d6eee3
11➜  ~ # Find the host path of the container filesystem (in this case is a btrfs volume)

So, what happened here:

  1. While running and stopping state, the container has an allocated filesystem on the host.
  2. Removing a container removes the associated filesystem too.

If you want to deep-dive more into this subject, I cannot recommend more those excellent readings:

  1. Deep Dive into Docker Internals - Union Filesystem
  2. Where are my container’s files? Inspecting container filesystems

Now that we have a clearer understanding of how Docker manages the filesystem, it is easily understandable how risky it can be to use a container without proper data persistency layer. This is exactly where docker volumes come in handy.

Docker volumes and bind mounts
Docker volumes and bind mounts

Bind mounts 

As the documentation states: “Bind mounts have been around since the early days of Docker. Bind mounts have limited functionality compared to volumes. A file or directory on the host machine is mounted into a container when you use a bind mount. The file or directory is referenced by its absolute path on the host machine. By contrast, when you use a volume, a new directory is created within Docker’s storage directory on the host machine, and Docker manages that directory’s contents.”

This is all you need to bind mount a host directory inside a container:

➜ docker run -v <host-path>:<container-path> <container>

Let’s see a quick real-world example of how bind mounts work (to view this asciinema, please refer to the source here):

And yes, this is precisely where all the problem begins.

A bind mount is a way to mount the host filesystem inside a container, and you can imagine if a VM is in the middle of us and the container, everything gets more complicated.

From 10 thousand feet, it works like this:

Docker bind mount diagram

So, when you mount a path from your Mac, you are just asking the Linux VM to mount the path of the network-shared filesystem of your Mac.

Usually, you do not need to configure this tedious part manually; the tools automatically do it for you.

You can find it what is mounted on Docker Desktop under:

Preferences -> Resources -> File sharing

Docker Desktop bind mount settings

As you can see from the image, we are mounting local paths like /Users as mount path on the Linux VM, and thanks to this, we can mount Mac directories as they were local:

As the documentation says:

Volumes are the preferred mechanism for persisting data generated by and used by Docker containers. While bind mounts depend on the host machine’s directory structure and OS, volumes are completely managed by Docker. Volumes have several advantages over bind mounts:

Volumes have several advantages:

  • Volumes are easier to back up or migrate than bind mounts.
  • You can manage volumes using Docker CLI commands or the Docker API.
  • Volumes work on both Linux and Windows containers.
  • Volumes can be more safely shared among multiple containers.
  • Volume drivers let you store volumes on remote hosts or cloud providers, to encrypt the contents of volumes, or to add other functionality.
  • New volumes can have their content pre-populated by a container.
  • Volumes on Docker Desktop have much higher performance than bind mounts from Mac and Windows hosts.

Well, there’s nothing to add here; the advantages of volumes vs. bind mounts are apparent, especially the last point.

But the biggest drawback is the developer experience; they are not meant to satisfy this requirement from the beginning, and using them for coding is counterintuitive or not usable.

Let me demonstrate in practice how they work; I’ll show you in order:

  1. A javascript node API up and running on localhost
  2. Development lifecycle on the host
  3. Create a Docker Volume
  4. Create a container using the docker volume
  5. Developing workflow inside a container with a volume

(I am the king of typos, I’ve tried to record this asciinema without errors ten times, and this is the best I’ve finally achieved 🏆🏆🏆)

As you have noted, the biggest drawback here is that any changes I am doing outside the container must be copied inside the container with docker cp.

could have mitigated this issue by installing VI inside the container, but I would have lost all my dotfiles, and usually, for Javascript, I prefer to use VSCode.

Volumes vs. bind-mounts 

Well, a long journey so far, and still not yet a solution 😎

At least we have learned two things:

  1. Bind mounts are the most natural way to move our files inside a container, but they suffer severe performance issues caused by file system sharing when the Docker engine runs in a VM.
  2. Volumes are way faster than bind mounts, but they lack the basics of the development experience (e.g., You and your local editor cannot see the files outside the container)


To demonstrate how much the performance is affected based on different scenarios (bind, volumes), I’ve created a simple test suite, nothing super fancy, just running some npm install tests on an empty create-react-app project.

Let’s see them in action:


  1. Pane top: macOS – Docker Desktop – virtioFS enabled
  2. Pane bottom: Linux

Tests (npm install):

  1. Native node on the host
  2. Docker without bind/volumes
  3. Docker with a bind mount + a volume just for node_modules
  4. Docker with a bind mount

Syntethic results 

TestOperating systemTime (s)
Docker – Bind MountLinux6.81
Docker – Bind Mount + VolumeLinux6,18
Docker – Bind MountmacOS7.65
Docker – Bind Mount + VolumemacOS21.05 🏆

And finally, we can see the performance impact results; macOS is more or less x3.5 times slower (10x times slower when using gRPC Fuse) when using just the bind mount, and the culprit here is the node\_modules directory [328M and 37k files just for an empty React app].

Moving this directory (node_modules) in a Volume makes the timing on par with Linux: 7.65s.

I’ve just taken Node as an example. Still, other development ecosystems are affected by the same issue (yes, PHP, I am looking at you and your vendor👀), or more generic directories with hundreds of thousands of small files are devilish for performance.


Now that we have a general overview of the moving pieces, how they work, and can be combined, the next question is:

What is the recommended method for decent performance and a good DX with Docker on Mac?

This is an excellent question!

Use VirtioFS
Use VirtioFS

The short answer for now is: Docker Desktop for Mac with VirtioFS, is a good compromise between performance and DX, even if it is slower than Linux; for most cases, it is a negligible difference.

When developing a new project in Node or PHP, you’re not going to reinstall your node_modules/vendor from scratch every time, it is rare, and in that rare cases, you’ll spend a bit more seconds.

Just keep in mind that:

  1. It is a closed-source product
  2. It requires a license depending on the usage
  3. Since it is a pretty recent technology, many issues and regressions remain.

So, what are the alternatives?

Bind mounts + Volume 

As the results below show, this is the best approach to have almost native performance, but it comes with significant DX issues.

We cannot see from our host the files being written by the container, and this is a big issue that can impact how we write the software and how our IDE will be capable of understanding the codebase we are working on.

How we can fix it ? Well depends on how you are used to develop.

Terminal editor’s users 

The only thing you need here is a container with the editor and the tools you need; mount your dotfiles and your code, and that’s it; you’ll enjoy an almost native experience.

> docker run --rm -v $HOME/.vimrc:/home/node/.vimrc -v $PWD:/usr/src/app node:lts bash

GUI Editors / IDE users 

Here things become more complicated.

Desktop applications are bound to the operating system they are designed for, and they usually cannot understand much of the underlying abstractions, like a filesystem inside a Docker container.

As the problem is that we cannot read or write files from and to the docker volume, we need a tool capable of this two-way syncing.

One of the most prominent solutions is Mutagen.

Mutagen allows syncing the files in both directions from/to the host/container when they happen. You can find here how to install it and how to configure it.

Not very easy to grasp at the beginning since it is composed of a daemon, a CLI tool, and some configuration files. It natively supports Composer and has also been a part of the Docker Desktop experimental feature, then deprecated and then again by the Mutagen authors as a Docker Desktop extension.

The last worth mentions, it is also supported and integrated by the DDEV project.

DDEV is a tool to manage local development environments for PHP projects (it started with Drupal ❤️) and then extended to many more frameworks. This is the best plug-and-play and battery-included choice to manage your PHP project with Docker, no matter the operating system you run.

Well, what if we want to avoid installing other moving parts? Can we run our GUI Editor as a Docker container so we can access the files?

You can run them quite easily on Linux, but there isn’t a comparable straightforward solution to run Linux GUI applications on macOS; unless you install XQuartz (Xorg for macOS) and do some tricks.

Microsoft here did a very cool thing instead; they implemented a Wayland compositor for Windows capable of natively running Linux GUI applications: WSLg

Anyway, this is not a very practical way to use an editor, which will always be very limited and poorly integrated with the operating system.

The best solution would be to have an IDE capable of running on your local system while simultaneously being capable of using Docker Containers, having the best of both worlds.

Should we invent it? Luckily for us, no, we shouldn’t because someone already did it, and I am talking about Development Containers

Development Containers 

An open specification for enriching containers with development specific content and settings.

A Development Container (or Dev Container for short) allows you to use a container as a full-featured development environment. It can be used to run an application, to separate tools, libraries, or runtimes needed for working with a codebase, and to aid in continuous integration and testing. Dev containers can be run locally or remotely, in a private or public cloud.

Not more to add here; the intent and the specs are very straightforward and clear about the goals.

Microsoft created this project, and the spec is released under the CC4 license.

Here you can find a list of “supporting tools” for the moment is almost “all Microsoft” for the editors part and cloud services; we have, of course, Visual Studio Code and GitHub Codespaces.

However, the project is slowly getting attraction, even tho there are several competitors and compelling standards in this area.

Cloud companies and developer-focused startups envision a world made of cloud-based development environments, which have pros and cons. I’ll debate this topic in another post.

The most significant competitors now are:

How it works 

You need to create a .devcontainer/devcontainer.json file inside the project’s root, and a supporting editor (AKA VsCode) will just run it.

Developing inside a container
Developing inside a container

You can find here a very good quick start. It covers almost all aspects, including using it with Docker Compose.

There is also a very nice guide on how to use it to improve the performance of macOS using Volumes instead of just bind mounts, which we have already discussed.

To make it easily understandable (at least for me), I’ve created a PoC project to connect all the wires; the project lives here: and it’s an empty Backstage application to test the entire development workflow using the VSCode Dev Containers integration.

To conclude, the overall idea is excellent, and since it is an open standard, it could be easily adopted by other vendors, and there are yet some efforts ongoing:

  1. Gitpod
  2. Jetbrains
  3. nVIM

To summarize the key points, i like much:

  1. Everything is Container-based.
  2. I can define custom VSCode extensions: I can define a shared development environment between team members.
  3. Thanks to the Development containers features., I can use Docker and Docker-compose inside the container.
  4. SSH works out of the box (you must have the ssh-agent up and running)/
  5. I can reuse the very same configuration locally or in the cloud.


This post started with the intent to quickly explain how to improve the performance of Docker on macOS, but at the same time, I felt the need to leave nothing behind of the basic concepts that are fundamentals to understand and get out the max from your system.

The big question here is, why not just use Linux?

This isn’t a trivial question; I use Linux as my daily driver (I’m writing this post on Linux), and I consider it the best development environment you can use.

But the hardware ecosystem must be taken into account, especially since the Apple Silicon machines are in the market; they are so great in terms of performance, battery life, and service.

So why don’t you get the best of both worlds? Machines are powerful enough today to run them seamlessly. There are other creative ways to combine them, as Michal Hashimoto did, merging macOS and NixOS, lovely.

Use what you like and what you find better for your workflow and, why not, what makes you happy today.

This is also a gift for the future me; next time, I should explain to someone how Docker works on Linux and outside, and I’ll use this guide as a general reference.

Thanks for reading all of this, and if you find something wrong or want to discuss some topics further, get in touch with me.
