If you're running macOS or Windows you have a few options for installing Docker. There's even a third way too, and we'll compare them here.

You'll understand the Docker container build and deploy tasks for a.NET Core application. The Docker platform uses the Docker engine to quickly build and package apps as Docker images. These images are written in the Dockerfile format to be deployed and run in a layered container. That doesn’t mean you can’t use Docker on Mac or Windows. In fact, there’s Docker for Mac and Docker for Windows. I won’t go into details on how to install Docker on your machine in this post. If you’re on a Linux machine, this guide will help you get Docker up and running. Now that you have Docker set up on your machine, you’re one. Have a VirtualBox based install of Docker for Win/Mac, rather than the newer HyperV or xhyve releases. Have machines in the cloud that you'd like to manage from docker-machine; docker-machine includes boot2docker images to do an install and it acts as a wrapper to setting the docker environment variables to point the client to a remote host. Use Docker Tools in Visual Studio on Windows.; 4 minutes to read; N; G; S; M; In this article. The developer workflow when using the Docker Tools included in Visual Studio 2017 version 15.7 and later, is similar to using Visual Studio Code and Docker CLI (in fact, it's based on the same Docker CLI), but it's easier to get started, simplifies the process, and provides greater. Host.docker.internal exists only in Windows WSL because Docker Desktop for Windows runs Docker daemon inside the special WSL VM Docker-Desktop. It has its own localhost and its own WSL2 interface to communicate with Windows. This VM has no static IP.

Quick Jump: OS and Hardware Requirements|Pros and Cons|Which One Should I Use?

If you’re on macOS or Windows you can install Docker with:

  1. Docker for Mac / Windows (now known as Docker Desktop)
  2. Docker Toolbox
  3. Running your own Virtual Machine and installing Docker yourself

All 3 of those options have their own pros and cons and in this article we’re going to cover them. If you’re looking for a high level overview of what Docker for Mac / Windows and Docker Toolbox is, then check out this article on getting to know Docker’s ecosystem.

OS and Hardware Requirements

It’s helpful to know what you can install before we compare everything, so let’s do that:

Docker for Mac (Docker Desktop)

Docker for Mac requires that you’re running Mojave 10.14+ or newer with an Intel CPU. M1 support is on its way.

You can run VirtualBox 6+ alongside Docker Desktop. This is pretty useful because you might have some legacy apps running in Vagrant / VirtualBox to deal with (I know I do!).

Docker for Windows (Docker Desktop)

As of May 27th 2020, Microsoft released Windows 10 build 2004 (Spring 2020) that allows you to run Docker Deskop on all editions of Windows 10, including Home thanks to WSL 2.

As of August 2020, Microsoft enabled WSL 2 support for Windows 10 builds 1903 + 1909.

For years prior to that you could only run it on Windows Pro, Enterprise or any edition that had Hyper-V available, but since August 2020 pretty much all supported versions of Windows 10 can use Docker Desktop.

You can also run VirtualBox 6+ alongside Docker Desktop too in case you have older projects using VirtualBox (perhaps with Vagrant too).

Docker Toolbox

Prior to mid-2020 this was still a reasonable way to run Docker on machines that couldn’t run Docker Desktop, but that’s no longer the case.

It’s now considered legacy and as of late 2020 it’s been officially deprecated.

Unless you’re using unsupported versions of Windows or have a really really ancient Mac you shouldn’t need to ever use this tool.

But if you’re in a pinch and you absolutely must use it, technically it’s still available at https://github.com/docker/toolbox/releases, but it’s no longer maintained by Docker.

Your own Virtual Machine

Docker will happily run inside of VirtualBox, VMWare Workstation or any other Type 1 / 2 Hypervisor that’s running a major distribution of Linux as a guest OS.

If for whatever reason you can’t use Docker Desktop then this solution would be better than using Docker Toolbox since you can install supported versions of Docker and you have full control over the environment.

Pros and Cons

Now for the good stuff!

Docker for Mac / Docker for Windows (Docker Desktop)

Pros

  • Offers the most “native” experience, you can easily use any terminal you you want since Docker is effectively running on localhost from macOS / Windows’ POV.

  • Docker is heavily developing and polishing this solution.

Cons

  • On certain macOS hardware combos the volume performance can be a little slow.

  • I can legit say there are not any “wow this sucks!” cons for Windows, it’s really solid.

Docker

Docker Toolbox

Pros
  • Offers an “out of the box” Docker experience if you have no other choice.
Dinghy Vs Docker For Mac
Cons

  • It’s deprecated by Docker and will receive no future maintenance.

  • You need to either use the Docker Quickstart Terminal, or configure your own terminal to connect to the Docker Daemon running a VM.

  • Not a native solution, so you’ll need to access your Docker Machine’s IP address if you’re developing web apps. Example: 192.168.99.100 instead of localhost.

  • Unless you jump through hoops, your code needs to live in your Windows user directory such as C:UsersNicksrcmyapp. Otherwise Docker won’t be able to find it.

  • Suffers from typical VirtualBox edge case bugs and mount performance issues.

Your own Virtual Machine

I’m not going to bother listing a pros and cons here because I wouldn’t recommend doing this UNLESS you’re stuck on Windows 7 / 8 or an older version of Windows 10 like 1809.

But more on that in a bit.

Which One Should I Use?

If you’re interested in Docker, you’re a smart person and you probably came to the conclusion that using Docker for Mac or Docker for Windows is a good idea as long as you can run it.

My recommendation would be to try Docker for Mac / Windows first, and test it against your actual use cases. The performance issues may or may not be a concern, especially since everyone’s needs and computer specs are different.

I’ve been using Docker Desktop on Windows for full time development since late 2018 and it’s been nothing short of fantastic. Currently I use it with WSL 2, but it was really good with WSL 1 along with Hyper-V too.

Stuck on an Old Version of Windows and Like Linux?

I want to mention a “roll your own VM” solution for Windows users because I feel like there’s an even better way to run Docker on Windows if you also like Linux and are stuck not being able to use modern versions of Windows 10.

It involves running VMWare Player in a special mode called “Unity mode”. This basically allows you to run Windows and Linux together seamlessly as 1 operating system.

There’s no dual booting and Linux applications (even graphical apps) run in their own floating windows. Then you can install Docker natively on Linux inside of the VM.

The performance is excellent and the entire set up is free too.

I used this set up for about 5 years until Docker Desktop was available. It gives you the best of both worlds. For example, I run high end audio / video apps on Windows while recording courses and screencasts that cover Linux content. It all works great (even for full time development).

You can watch a video guide and see screenshots on how to do that in this post on creating an awesome Linux development environment in Windows.

Are you using the Docker Toolbox, Docker for Mac / Windows or your own VM?

Docker for Mac offers a Mac native application that installs in /Applications. It creates symlinks (symbolic links) in /usr/local/bin for docker and docker-compose to the Mac versions of the commands in the application bundle.

The Docker for Mac bundle installs:

  1. Docker Engine
  2. Docker CLI Client
  3. Docker Compose
  4. Docker Machine

Are you already running Docker Toolbox and/or Docker Machine?

If so, you need to do a little more work. First, check whether Docker Toolbox environment variables are set:

If you don’t get output, you can go ahead and use Docker for Mac. However, if you do get output (like in the example), you need to unset the Docker variables so the client can talk to the Docker for Mac Engine. Run:

If you use Bash, you can use unset ${!DOCKER_*} to unset all of the Docker environment variables (this does not work in other shells, like zsh or csh).

When you run env | grep DOCKER now, you should see no output.

Running Docker Toolbox and Docker for Mac on the same host

You can run both Docker Toolbox and Docker for Mac on the same system, but not at the same time.

When you use Docker for Mac, you need to unset all of your environment variables, using one of the methods above. When you want to use a VirtualBox VM you have set up with docker-machine, simply run eval $(docker-machine env default) (assuming you want to target the machine “default”).

Docker Machine

Docker for Mac does not affect previous machines created via Docker Machine, The installation gives you the option to copy containers and images from your local default machine if you have one.

Requirements

Dinghy Vs Docker For Mac Computers

You must have a Mac:

  1. 2010 or newer, with Intel’s hardware Memory Management Unit (MMU).
  2. OS X 10.10.3 Yosemite or newer (or macOS).
  3. At least 4 GB of RAM.
  4. You must not have a VirtualBox installation earlier than version 4.3.30 on your system. If you do, you’ll need to uninstall it.

Before You Install

Take a few minutes to understand some key concepts before you install Docker.

Docker For Mac Ip

On an “out-of-the-box” Linux installation, the Docker client, daemon, and all containers run directly on localhost, meaning you can access ports on a Docker container using localhost addressing; something like localhost:8080 or 0.0.0.0:8376.

On macOS, Docker’s daemon runs inside a Linux VM. The macOS Docker client talks to the Docker host VM, and your containers run on the host. You cannot use localhost in this setting; instead, the container’s ports map to the VM’s ports. If your VM has the IP address 10.0.0.5, access the ports like 10.0.0.5:8000 or 10.0.0.5:8376.

Installation

  1. Download Docker.
  2. Double-click the DMG file, and drag-and-drop Docker into your Applications folder.
  3. You need to authorize the installation with your system password.
  4. Double-click Docker.app to start Docker.
  5. The whale in your status bar indicates Docker is running and accessible.
  6. Docker presents some information on completing common tasks and links to the documentation.
  7. You can access settings and other options from the whale in the status bar. a. Select About Docker to make sure you have the latest version.

That’s it!

Verification

Check versions of Docker Engine, Compose, and Machine.

Run a Dockerized web server to make sure everything works:

If you do not have the image locally, Docker pulls it from Docker Hub (more on this later). Visit http://localhost to bring up your new homepage; you should see:

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

For online documentation and support please refer to nginx.org.Commercial support is available at nginx.com.

Thank you for using nginx.

Common Pitfalls

Operating System

Unfortunately, if you do not run “Mountain Lion” or later, you cannot run Docker for Mac. You can upgrade your OS to the most recent viable version, provided your system supports it.

Shell Scripts

If you use a shell script to set the Docker environment variables every time you open a command window (Terminal), you need to unset the variables every time you use Docker for Mac (alternately, you can write a shell script to follow behind and unset the variables).

Multiple Docker Versions

Docker for Mac replaces docker and docker-compose with its own versions; if you already have Docker Toolbox on your Mac, Docker for Mac still replaces the binaries. You want the Docker client and Engine to match versions; mismatches can cause problems where the client and host cannot communicate. If you already have Docker Toolbox, and then you install Docker for Mac, you may get a newer version of the Docker client. Running docker version in a command shell displays the version of the client and server you have on your system.
