Install Docker Toolbox on macOS

Legacy desktop solution. Docker Toolbox is for older Mac and Windows systems that do not meet the requirements of Docker Desktop for Mac and Docker Desktop for Windows. We recommend updating to the newer applications, if possible.

Docker Toolbox provides a way to use Docker on older Macs that do not meet minimal system requirements for Docker Desktop for Mac.

What you get and how it works

Docker Toolbox includes the following Docker tools:

Docker CLI client for running Docker Engine to create images and containers
Docker Machine so you can run Docker Engine commands from macOS terminals
Docker Compose for running the docker-compose command
Kitematic, the Docker GUI
the Docker QuickStart shell preconfigured for a Docker command-line environment
Oracle VM VirtualBox

Because the Docker Engine daemon uses Linux-specific kernel features, you can’t run Docker Engine natively on macOS with Docker Toolbox. Instead, you must use the Docker Machine command, docker-machine, to create and attach to a small Linux VM on your machine. This VM hosts Docker Engine for you on your Mac.

Tip: One of the advantages of the newer Docker Desktop for Mac solution is that it uses native virtualization and does not require VirtualBox to run Docker.

Step 1: Check your version

Your Mac must be running macOS 10.8 “Mountain Lion” or newer to run Docker software. To find out what version of the OS you have:

Choose About this Mac from the Apple menu.

The version number appears directly below the words macOS.
If you have the correct version, go to the next step.

If you aren’t using a supported version, you could consider upgrading your operating system.

If you have macOS 10.13.0 High Sierra or newer, consider using Docker Desktop for Mac instead. It runs natively on the Mac, so there is no need for a pre-configured Docker QuickStart shell. It uses the native macOS Hypervisor framework for virtualization, instead of Oracle VirutalBox. Full install prerequisites are provided in the Docker Desktop for Mac topic in Docker Desktop for Mac.

Step 2: Install Docker Toolbox

Note: Docker are no longer maintaining the download.docker.com url for Docker Toolbox, therefore an unsigned warning (verified publisher dialog) is displayed during the installation process.

To download the latest version of Docker Toolbox, go to Toolbox Releases and download the latest .pkg file.
Install Docker Toolbox by double-clicking the package or by right-clicking and choosing “Open” from the pop-up menu.

The installer launches an introductory dialog, followed by an overview of what’s installed.
Press Continue to install the toolbox.

The installer presents you with options to customize the standard installation.

By default, the standard Docker Toolbox installation:
- installs binaries for the Docker tools in /usr/local/bin
- makes these binaries available to all users
- updates any existing Virtual Box installation
For now, don’t change any of the defaults.
Press Install to perform the standard installation.

The system prompts you for your password.
Provide your password to continue with the installation.

When it completes, the installer provides you with some shortcuts. You can ignore this for now and click Continue.

Then click Close to finish the installer.

Step 3: Verify your installation

To run a Docker container, you:

create a new (or start an existing) Docker Engine host running
switch your environment to your new VM
use the docker client to create, load, and manage containers

Once you create a machine, you can reuse it as often as you like. Like any Virtual Box VM, it maintains its configuration between uses.

Open the Launchpad and locate the Docker Quickstart Terminal icon.

Click the icon to launch a Docker Quickstart Terminal window.

The terminal does a number of things to set up Docker Quickstart Terminal for you.

 The Docker Quick Start Terminal is configured to use Docker with the "default" VM.

Click your mouse in the terminal window to make it active.

If you aren’t familiar with a terminal window, here are some quick tips.

The prompt is traditionally a $ dollar sign. You type commands into the command line which is the area after the prompt. Your cursor is indicated by a highlighted area or a | that appears in the command line. After typing a command, always press RETURN.

Type the docker run hello-world command and press RETURN.

The command does some work for you, if everything runs well, the command’s output looks like this:

 $ docker run hello-world
 Unable to find image 'hello-world:latest' locally
 latest: Pulling from library/hello-world
 535020c3e8ad: Pull complete
 af340544ed62: Pull complete
 Digest: sha256:a68868bfe696c00866942e8f5ca39e3e31b79c1e50feaee4ce5e28df2f051d5c
 Status: Downloaded newer image for hello-world:latest

 Hello from Docker.
 This message shows that your installation appears to be working correctly.

 To generate this message, Docker took the following steps:
 1. The Docker Engine CLI client contacted the Docker Engine daemon.
 2. The Docker Engine daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker Engine daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker Engine daemon streamed that output to the Docker Engine CLI client, which sent it
    to your terminal.

 To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Optional: Add shared directories

By default, Toolbox only has access to the /Users directory and mounts it into the VMs at /Users. If your project lives elsewhere or needs access to other directories on the host filesystem, you can add them.

Use the VirtualBox GUI

You can configure shared folders in the VirtualBox UI.

Open the VirtualBox UI.
Click the Settings gear, then go to Shared Folders.
Select any existing listing under Machine Folders, then click the + icon.
- Choose the Folder Path on the host, enter the Folder Name for within the VM (or take the default, which is the same name as on the host), and configure any additional options you need.
- Choose Auto-mount if you want the folder to automatically be mounted into the VM, and choose Make Permanent for it to be considered a permanently shared folder.
Click OK to add the new folder to the Shared Folders list.
Click OK again to save your changes and exit the Settings dialog.

Use the command line

You can configure shared folders using a command like the following:

$ mount -t vboxsf -o uid=1000,gid=50 your-other-share-name /some/mount/location

This command mounts /some/mount/location into the VM at /your-other-share-hame, owned by UID 1000 and GID 50.

Note: The autommount and permanent mount options are not supported using the command line.

How to uninstall Toolbox

Removing Toolbox involves removing all the Docker components it includes.

A full uninstall also includes removing the local and remote machines you created with Docker Machine. In some cases, you might want to keep machines created with Docker Machine.

For example, if you plan to re-install Docker Machine as a part of Docker Desktop for Mac you can continue to manage those machines through Docker. Or, if you have remote machines on a cloud provider and you plan to manage them using the provider, you wouldn’t want to remove them. So the step to remove machines is described here as optional.

To uninstall Toolbox on a Mac, do the following:

List your machines.

$ docker-machine ls
NAME                ACTIVE   DRIVER       STATE     URL                        SWARM
dev                 *        virtualbox   Running   tcp://192.168.99.100:2376
my-docker-machine            virtualbox   Stopped
default                      virtualbox   Stopped

Optionally, remove each machine. For example:
```
$ docker-machine rm my-docker-machine
Successfully removed my-docker-machine
```
This step is optional because if you plan to re-install Docker Machine as a part of Docker Desktop for Mac, you can import and continue to manage those machines through Docker.
In your “Applications” folder, remove the “Docker” directory, which contains “Docker Quickstart Terminal” and “Kitematic”.
Run the following in a command shell to fully remove Kitematic:
```
$ rm -fr ~/Library/Application\ Support/Kitematic
```
Remove the docker, docker-compose, and docker-machine commands from the /usr/local/bin folder. Docker Desktop for Mac and Brew may also have installed them; in case of doubt leave them, or reinstall them via Brew, or rerun Docker Desktop for Mac (no need to reinstall it).
```
$ rm -f /usr/local/bin/docker
$ rm -f /usr/local/bin/docker-compose
$ rm -f /usr/local/bin/docker-machine
```
Optionally, remove the ~/.docker/machine directory.

This directory stores some configuration and/or state, such as information about created machines and certificates.
Uninstall Oracle VirtualBox, which is installed as a part of the Toolbox install.
