What to know before you install. README FIRST for Docker Toolbox and Docker Machine users. If you are already running Docker on your machine, first read Docker Desktop for Mac vs. Docker Toolbox to understand the impact of this installation on your existing setup, how to set your environment for Docker Desktop on Mac, and how the two products. I saw a problem on the following URL: Install Docker for Mac and Install Docker for Windows; Suggestions for a fix. It would be awesome if Docker for Mac and Docker for Windows could be downloaded without logging into Docker Store as not to make users jump through hoops. This was already previously possible, if I remember correctly. Other ways to install it. In this post, I want to show you how to install Docker by using brew which installation process I wrote last time. For me, it’s the easiest and safest way. But there are a few other possibilities to install it on Mac OS.

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 Macsthat do not meetminimal 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-specifickernel features, you can’t run Docker Engine natively onmacOS with Docker Toolbox. Instead, you must use theDocker Machine command, docker-machine, to create andattach to a small Linux VM on your machine. This VM hostsDocker Engine for you on your Mac.

Tip: One of the advantages of the newerDocker Desktop for Mac solution is thatit uses native virtualization and does not requireVirtualBox to run Docker.

Step 1: Check your version

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

  1. Choose About this Mac from the Apple menu.

    The version number appears directly below the words macOS.

  2. 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 10.10.3 Yosemite 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 forDocker Toolbox, therefore an unsigned warning (verified publisher dialog) isdisplayed during the installation process.

  1. To download the latest version of Docker Toolbox, go to ToolboxReleases and download thelatest .pkg file.

  2. Install Docker Toolbox by double-clicking the package or by right-clickingand choosing “Open” from the pop-up menu.

    I have to be able to burn discs for work, and with the latest driveless Mac Pros and the USB Superdrive, it's an exercise in futility. Maybe I'll find a six-for-one sale on blank discs. External dvd drive for mac I am beyond frustrated at Mac's ongoing attempt to dictate to its users what it feels is best for them.

    The installer launches an introductory dialog, followed by an overview of what’s installed.

  3. 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.

  4. Press Install to perform the standard installation.

    The system prompts you for your password.

  5. 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 anyVirtual Box VM, it maintains its configuration between uses.

  1. Open the Launchpad and locate the Docker Quickstart Terminal icon.

  2. 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.

  3. 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 thecommand line which is the area after the prompt. Your cursor is indicatedby a highlighted area or a that appears in the command line. Aftertyping a command, always press RETURN.

  4. 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:

Optional: Add shared directories

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

Use the VirtualBox GUI

You can configure shared folders in the VirtualBox UI.

  1. Open the VirtualBox UI.

  2. Click the Settings gear, then go to Shared Folders.

  3. Select any existing listing under Machine Folders, thenclick the + icon.

    • Choose the Folder Path on the host, enter the Folder Namefor within the VM (or take the default, which is the same nameas on the host), and configure any additional options you need.

    • Choose Auto-mount if you want the folder to automaticallybe mounted into the VM, and choose Make Permanent for itto be considered a permanently shared folder.

  4. Click OK to add the new folder to the Shared Folders list.

  5. 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:

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 usingthe command line.

How to uninstall Toolbox

Removing Toolbox involves removing all the Docker components it includes.

Install Docker For Mac Download

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

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

To uninstall Toolbox on a Mac, do the following:

  1. List your machines.

  2. Optionally, remove each machine. For example:

    This step is optional because if you planto re-install Docker Machine as a partof Docker Desktop for Mac, you can import andcontinue to manage those machines through Docker.

  3. In your “Applications” folder, remove the “Docker” directory,which contains “Docker Quickstart Terminal” and “Kitematic”.

  4. Run the following in a command shell to fully remove Kitematic:

  5. Remove the docker, docker-compose, and docker-machine commands fromthe /usr/local/bin folder. Docker Desktop for Mac and Brew may also haveinstalled them; in case of doubt leave them, or reinstall them via Brew, orrerun Docker Desktop for Mac (no need to reinstall it).

  6. Optionally, remove the ~/.docker/machine directory.

    This directory stores some configuration and/or state, such as informationabout created machines and certificates.

  7. Uninstall Oracle VirtualBox, which is installed as a part of theToolbox install.

How to install Docker on your Mac and configure it for SQL Server.

Before you install SQL Server on a Mac, you need to install Docker. This is because the Mac installs (and runs) SQL Server from a Docker container image.

Below are instructions for downloading and installing Docker (it's pretty simple), then configuring it for SQL Server. By 'configuring' I simply mean that you need to allocate enough memory to Docker so that SQL Server can run.

  1. Download Docker

    Go to the Docker Community Edition for Mac download page and click Get Docker.

  2. Install Docker

    Double-click on the downloaded .dmg file and then drag the Docker.app icon to your Application folder.

  3. Launch Docker

    Launch Docker the same way you'd launch any other application (via Launchpad, the Applications folder, etc).

    When you first Launch Docker, you might be prompted for your password. Go ahead and provide your password — Docker needs this in order to install its networking components and links to the Docker apps.

  4. Increase the Memory

    SQL Server needs at least 3.25GB to run, but Docker only allocates 2GB by default. Therefore you should increase this allocation to allow SQL Server to run. Increase it to 4GB (to be on the safe side).

    To do this:

    1. Select Preferences from the little Docker icon in the top menu
    2. Select Advanced (if it's not already selected)
    3. Slide the memory slider up to 4GB
    4. Click Apply & Restart

Now you can Install SQL Server

Now that you've installed Docker and increased its memory allocation, you can go ahead and install SQL Server on your Mac.

What Exactly is Docker?

Docker is a platform that enables software to run in its own isolated environment. It achieves this through the use of 'containers'.

As explained on the Docker website:

A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings.

The main benefit of Docker containers is that they enable us to run software across different computer systems without encountering configuration issues. Because the software is running in its own isolated environment, all configuration settings are already included in the container.

Docker is a popular option for development environments, where software can be developed and tested without having to worry about whether all computers are configured the same. Containers isolate software from its surroundings, for example differences between development and staging environments and help reduce conflicts between teams running different software on the same infrastructure.

But as we can see with SQL Server, Docker can also be used to download and run software on a platform that wouldn't normally be able to run that software (such as running SQL Server on a Mac or Linux).

Why do we need to use Docker to run SQL Server?

Prior to its 2017 release, SQL Server wasn't available for the Mac. The only way you could run SQL Server on a Mac was to use a virtual machine such as VirtualBox, Parallels Desktop, VMware Fusion, or Bootcamp running the Windows operating system. To do this, you had to create the virtual machine, purchase Windows and install it onto that virtual machine, and then finally install SQL Server.

While this is still a viable option today, SQL Server 2017 has provided you with new option: Install SQL Server via Docker — without needing to purchase Windows. The Docker container image contains everything needed to run SQL Server.
