The platform known as Docker has become one of the most popular ways to run a new kind of software known as containerized apps. And while Docker's mainly aimed at programmer types, there are a few reasons why everyday Mac users might want it around as well.
What are containerized apps?
Containerized apps are tidy little packages of software that bundle nearly everything they need to run in a single, self-contained box.
Programmers can write an app once and know that it'll run anywhere, every time. Businesses get an efficient way to run lots of apps on a single server without straining their hardware. And users get apps that won't sprawl out and spread files into their hard drives' nooks and crannies, nor start hogging memory and slowing down the entire computer.
How does Docker work?
Docker uses emulation to ensure that the same containerized app can run on any machine where Docker's installed. And because it emulates an operating system – usually some flavor of Linux, though you can also set it up to run enterprise versions of Windows – instead of actual chip hardware, it demands a lot less memory and processing power than traditional virtual machines like Parallels or VMware Fusion.
Unlike those apps, you can't use Docker to run Windows on your Mac – though you can run at least limited versions of Linux with it. And you can use Docker to run apps that weren't originally written for the Mac.
Once you fire up the easy-to-install Docker app, it runs in the background, and you can use the Terminal or another app called Kitematic (we'll get to that later) to install and run containerized apps. Download dictionary for mac os x 10.4.11.
Who is Docker for?
As mentioned above, Docker's mainly aimed at programmers who want to containerize existing apps or write new ones, and businesses and IT folks who want to use its industrial-grade software.
There are Docker versions of familiar desktop apps like Firefox, Chrome, Skype, Spotify, image editor GiMP, and audio editor Audacity. But most of these apps already have native Mac versions. Running them in containers only makes sense if you like the technical challenge, want to keep a single app from hogging all your system's memory, or want to ensure that any malware you might pick up while browsing the web stays stuck inside its container, unable to escape to the rest of your Mac.
As of this writing, the main reason I've found to run Docker on a Mac is Pi-hole, originally made for the Raspberry Pi. Pi-hole can automatically block Web ads across your entire home network, and Docker's the only way to get it working on a Mac without also having a Raspberry Pi.
How to install Docker on your Mac
1. Create a Docker Hub account
Docker Hub keeps track of the containers you're running (or creating) and provides a one-stop shop to find new ones. Sign up for a Docker account with a unique Docker ID, your email, and a strong password.
2. Download Docker Desktop for Mac
Once you've signed up and signed in to Docker Hub, get Docker Desktop for Mac. It's got everything you'll need to run Docker in one Mac-friendly installer. Your Mac needs to be running Mac OS Sierra or later, and have at least 4GB of RAM.
3. Install Docker Desktop on your Mac
Open the
docker.dmg
file you downloaded, and drag the Docker app's cartoon whale icon into your Applications folder.4. Open and run Docker
When you run the Docker app, a little whale icon will appear on the right side of the menubar atop your screen. It'll take a few minutes to get running, and Docker may ask your permission to use services on your computer. The app will also prompt you to enter the Docker ID and password you just created.
When containers stop appearing and disappearing atop the little whale icon in the menubar, and you see a green dot at the top of the Docker menu next to 'Docker Desktop is running,' you're all set.
Consult the Preferences in the Docker menu to control how big a chunk of your hard drive Docker's allotted, and how much of your memory and CPU it's allowed to use, among other options.
5. Download and install Kitematic
Kitematic lets you install, manage, and remove your Docker containers from a single graphical interface — a lifesaver if you're not familiar or comfortable with the Terminal. You can install, and later open, Kitematic directly from the Docker app's menu:
Follow the link in that dialog box to install Kitematic. The app may ask for — you guessed it — your Docker ID and password again, just to keep track of your containers.
From Kitematic, you can search for and install new containers, and delete, edit, stop, or restart existing ones. If a container's running, Kitematic gives you an easy way to view its log files, which aren't readily visible from the Terminal. The interface is fairly intuitive, so feel free to play around and see what you can do.
In my tests, Kitematic came in most useful for deleting troublesome containers whose installation I'd somehow botched. Just find the container in the list on the left side of the Kitematic window, click the X icon next to it, and the container's gone completely, for good. You can always reinstall a package, either from the Terminal or by searching for it in Kitematic, and try again.
Where can I learn more about Docker for Mac?
Consult Docker for Mac's help files for more information about getting started, ways to test that your installation's up and running smoothly, and more things you can do with Docker. There's also a guide to teach you how to create your own containerized apps.
For less technically inclined folks, it's tough to find a good list of desktop apps that work with Docker. Docker Hub doesn't break desktop apps into their own category, but Jessie Frazelle compiled this list in 2015.

What to know before you install
System Requirements
- Windows 10 64-bit: Pro, Enterprise, or Education (Build 15063 or later).
- Hyper-V and Containers Windows features must be enabled.
- The following hardware prerequisites are required to successfully run ClientHyper-V on Windows 10:
- 64 bit processor with Second Level Address Translation (SLAT)
- 4GB system RAM
- BIOS-level hardware virtualization support must be enabled in theBIOS settings. For more information, seeVirtualization.
Note: Docker supports Docker Desktop on Windows based on Microsoft’s support lifecycle for Windows 10 operating system. For more information, see the Windows lifecycle fact sheet.
README for Docker Toolbox and Docker Machine users: Microsoft Hyper-V is required to run Docker Desktop. The Docker Desktop Windows installer enables Hyper-V if required, and restarts your machine. When Hyper-V is enabled, VirtualBox no longer works. However, any existing VirtualBox VM images are retained.
VirtualBox VMs created with
docker-machine
(including the default
onetypically created during Toolbox install) no longer start. These VMs cannot beused side-by-side with Docker Desktop. However, you can still usedocker-machine
to manage remote VMs.What’s included in the installer
The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.
Containers and images created with Docker Desktop are shared between alluser accounts on machines where it is installed. This is because all Windowsaccounts use the same VM to build and run containers.
Nested virtualization scenarios, such as running Docker Desktop on aVMWare or Parallels instance might work, but there are no guarantees. Formore information, see Running Docker Desktop in nested virtualization scenarios.
Note: Refer to the Docker compatibility matrix for complete Docker compatibility information with Windows Server.

Uninstall Docker Desktop
To uninstall Docker Desktop from your Windows machine:
- From the Windows Start menu, select Settings > Apps > Apps & features.
- Select Docker Desktop from the Apps & features list and then select Uninstall.
- Click Uninstall to confirm your selection.
Note: Uninstalling Docker Desktop will destroy Docker containers and images local to the machine and remove the files generated by the application.
Switch between Stable and Edge versions
Docker Desktop allows you to switch between Stable and Edge releases. However, you can only have one version of Docker Desktop installed at a time. Switching between Stable and Edge versions can destabilize your development environment, particularly in cases where you switch from a newer (Edge) channel to an older (Stable) channel.
For example, containers created with a newer Edge version of Docker Desktop maynot work after you switch back to Stable because they may have been createdusing Edge features that aren’t in Stable yet. Keep this in mind asyou create and work with Edge containers, perhaps in the spirit of a playgroundspace where you are prepared to troubleshoot or start over.
To safely switch between Edge and Stable versions, ensure you save images and export the containers you need, then uninstall the current version before installing another. For more information, see the section Save and Restore data below.
Save and restore data
You can use the following procedure to save and restore images and container data. For example, if you want to switch between Edge and Stable, or to reset your VM disk:
Docker Desktop For Mac Download Without Login Windows 10
- Use
docker save -o images.tar image1 [image2 ..]
to save any images you want to keep. See save in the Docker Engine command line reference. - Use
docker export -o myContainner1.tar container1
to export containers you want to keep. See export in the Docker Engine command line reference. - Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk.
- Use
docker load -i images.tar
to reload previously saved images. See load in the Docker Engine. - Use
docker import -i myContainer1.tar
to create a file system image corresponding to the previously exported containers. See import in the Docker Engine.
