System requirements

Expected behavior If allocated disk space is 128GB, container should be able to use 128GB (or close to). Actual behavior Allocated disk space does not have any impact on container disk space, which is 18GB for some reason on my machine. You do not have to increase the size for overlay or overlay2, which have a default base size of 500GB. Increase docker storage size If your Red Hat operating system uses device mapper as the docker storage driver, the base size limits the size of image and container to 10G.

You run a Docker image by using the docker run API. The command is as follows: $ docker run -p80:3000 yourusername/example-node-app. The command is pretty simple.
  • Docker security refers to the build, runtime, and orchestration aspects of Docker containers. It includes the Dockerfile security aspects of Docker base images, as well as the Docker container security runtime aspects—such as user privileges, Docker daemon, proper CPU controls for a container, and further concerns around the orchestration of Docker containers at scale.
Mac

Your Mac must meet the following requirements to successfully install Docker Desktop:

Base

  • Mac hardware must be a 2010 or a newer model with an Intel processor, with Intel’s hardware support for memory management unit (MMU) virtualization, including Extended Page Tables (EPT) and Unrestricted Mode. You can check to see if your machine has this support by running the following command in a terminal: sysctl kern.hv_support

    If your Mac supports the Hypervisor framework, the command prints kern.hv_support: 1.

  • macOS must be version 10.14 or newer. That is, Mojave, Catalina, or Big Sur. We recommend upgrading to the latest version of macOS.

    If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.

    Note: Docker supports Docker Desktop on the most recent versions of macOS. Docker Desktop currently supports macOS Mojave, macOS Catalina, and macOS Big Sur.

    As new major versions of macOS are made generally available, Docker stops supporting the oldest version and support the newest version of macOS.

  • At least 4 GB of RAM.

  • VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.

What’s included in the installer

The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.

Install and run Docker Desktop on Mac

  1. Double-click Docker.dmg to open the installer, then drag the Docker icon to the Applications folder.

  2. Double-click Docker.app in the Applications folder to start Docker. (In the example below, the Applications folder is in “grid” view mode.)

    The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.

    If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub.

  3. Click the Docker menu () to seePreferences and other options.

  4. Select About Docker to verify that you have the latest version.

Congratulations! You are now successfully running Docker Desktop.

If you would like to rerun the tutorial, go to the Docker Desktop menu and select Learn.

Automatic updates

Starting with Docker Desktop 3.0.0, updates to Docker Desktop will be available automatically as delta updates from the previous version.

When an update is available, Docker Desktop automatically downloads it to your machine and displays an icon to indicate the availability of a newer version. All you need to do now is to click Update and restart from the Docker menu. This installs the latest update and restarts Docker Desktop for the changes to take effect.

Uninstall Docker Desktop

Save and restore data

You can use the following procedure to save and restore images and container data. For example to reset your VM disk:

How To Increase The Size Of The Base Docker For Mac High Sierra

  1. 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.

  2. Use docker export -o myContainner1.tar container1 to export containers you want to keep. See export in the Docker Engine command line reference.

  3. Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk.

  4. Use docker load -i images.tar to reload previously saved images. See load in the Docker Engine.

  5. Use docker import -i myContainer1.tar to create a filesystem image corresponding to the previously exported containers. See import in the Docker Engine.
