Docker Desktop for Mac is the Community version of Docker for Mac.You can download Docker Desktop for Mac from Docker Hub.
On desktop systems like Docker Desktop for Mac and Windows, Docker Compose is included as part of those desktop installs. On Linux systems, first install the Docker Engine for your OS as described on the Get Docker page, then come back here for instructions on installing Compose on Linux systems. 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 latest stable release of FEniCS is version 2019.1.0, which was released on April 19th 2019. FEniCS on Docker To use our prebuilt, high-performance Docker images, first install Docker CE for your platform (Windows, Mac or Linux) and then run the following command: crayon-5f99e48d955fb569891960/ To run the FEniCS Docker image, use the command fenicsproject run. The preferred choice for millions of developers that are building containerized apps. Docker Desktop is a tool for MacOS and Windows machines for the building and sharing of containerized applications and microservices. Access Docker Desktop and follow the guided onboarding to build your first containerized application in minutes.
By downloading Docker Desktop, you agree to the terms of the Docker Software End User License Agreement and the Docker Data Processing Agreement.What to know before you install
Relationship to Docker Machine: Installing Docker Desktop on Mac does not affect machines you created with Docker Machine. You have the option to copy containers and images from your local default machine (if one exists) to the Docker Desktop HyperKit VM. Whenyou are running Docker Desktop, you do not need Docker Machine nodes running locally (or anywhere else). With Docker Desktop, you have a new, nativevirtualization system running (HyperKit) which takes the place of theVirtualBox system.System requirements
Your Mac must meet the following requirements to successfully install Docker Desktop:
*
Mac hardware must be a 2010 or a newer model, 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 or Catalina. 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 and macOS Catalina.
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
*
Double-click Docker.dmg to open the installer, then drag the Docker icon to the Applications folder.
*
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.
*
Click the Docker menu () to seePreferences and other options.
*
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.Uninstall Docker Desktop
To unistall Docker Desktop from your Mac:
*From the Docker menu, select Troubleshoot 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.
Experimental features are turned on by default on Edge releases. However, when you switch from a Stable to an Edge release, you must turn on the experimental features flag to access experimental features. From the Docker Desktop menu, click Preferences > Command Line and then turn on the Enable experimental features toggle. Click Apply & Restart for the changes to take effect.
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:
*
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 filesystem image corresponding to the previously exported containers. See import in the Docker Engine.

In this post, we are sharing Docker image for OpenCV 3.4.3, and the recently released OpenCV 3.4.4 and OpenCV 4.0. In addition to OpenCV, the image also has dlib and a Facial Landmark Detection example code.
Every day we receive a few emails and comments on our posts about OpenCV and Dlib installation. Even with the detailed and tested instructions, sometimes it is tough for people to get a system up and running. So, we have been thinking of providing a solution for people who have struggled with installation issues.
One way to solve this problem is to provide a Virtual Machine (VM) with all the libraries installed. A huge downside of using a VM is the large file people need to download. Sometimes it can be 10s of GBs.
A smarter and newer way to solve this problem is to provide a Docker image. Typically a Docker image size is much smaller than a VM. Our Docker image, for example, is just 1 GB in size (compressed size). In addition, it starts much faster than a VM and typically runs applications much faster compared to a VM. Docker is just one of those minimal things that can make your life exceedingly simple.
Also, as we’ll see, the same docker image can be used on Windows, Ubuntu and MacOS. If you are stuck with OpenCV installation or if you want to try out the new OpenCV-3.4.4 and OpenCV-4.0 ( released on 20th November 2018 ), without actually installing it on your system, this docker image is the perfect match for you.
This post is split into five sections
*Section 1: How to install Docker on Linux, MacOS and Windows.
*Section 2: How to use Docker image for OpenCV. This image also comes with dlib pre-installed.
*Section 3: How to run Facial Landmark Detection demo code on Docker Image
*Section 4: How to make changes to a Docker image.1. Docker Installation
Owncloud mac download. In this section, we will learn how to install Docker on Ubuntu, MacOS, and Windows.1.1 Installing Docker on Ubuntu
* To install docker on Ubuntu 16.04, first add the GPG key for the official Docker repository to the system:
* Add the Docker repository to APT sources:
* Next, update the package database with the Docker packages from the newly added repo:
* Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:
* You should see output similar to the following:
* Finally, install Docker: 1.2 Installing on MacOS
* To install Docker on MacOS desktop, first go to the Docker Store and download Docker Community Edition for Mac.
* Double-click Docker.dmg to open the installer, then drag Moby the whale to the Applications folder.
* Double-click Docker.app in the Applications folder to start Docker.
* You are prompted to authorise Docker.app with your system password after you launch it. Privileged access is needed to install networking components and links to the Docker apps.
The whale in the top status bar indicates that Docker is running, and accessible from a terminal.
Docker Mac Os Download1.3 Installing Docker Toolbox in Windows 7 or above
* Download and install Docker Toolbox for Windows. The installer adds Docker Toolbox, VirtualBox, and Kitematic to your Applications folder.
* On your Desktop, find the Docker QuickStart Terminal icon.
* Double click the Docker QuickStart icon to launch a pre-configured Docker Toolbox terminal.
* Press enter and the installation will be automatically started. Once done, the file will be present in
usersusername.dockermachinecacheboot2docker.iso.
* If the system displays a User Account Control prompt to allow VirtualBox to make changes to your computer, choose Yes.
The terminal does several things to set up Docker Toolbox for you. When it is done, the terminal displays the $ prompt.2 Install Docker OpenCV Image The docker image has been updated to enable X11-Forwarding and now also contain an example to test installation. Use docker pull to get the latest image.
To use the docker image, use the following instructions:
Once, the image is downloaded, we can start it using the following command
Let’s take a moment to examine this command in detail:
*–device=/dev/video0:/dev/video0 allows use of webcam
*-v /tmp/.X11-unix:/tmp/.X11-unix helps in X11 forwarding so that we can use functions like cv::imshow.
*-e is used to pass an environment variable.
*-it starts an interactive session
*-p sets up a port forward. This flag maps the container’s port to a port on the host system.
*/bin/bash runs .bashrc file on startup
The image has OpenCV 3.4.3 installed in /usr/local, OpenCV 3.4.4 in ~/installation/OpenCV-3.4.4 and OpenCV 4.0.0 in ~/installation/OpenCV-master.
To use Python environments:
For OpenCV 3.4.3,
Once you are in the iPython prompt, do
To deactivate the virtual environment use
Similarly for OpenCV 3.4.4 and OpenCV 4.0.0,
Once you are in the iPython prompt, do
To deactivate the virtual environment type
Once you are in the iPython prompt, doInstall Docker Mac Terminal3 Run Facial Landmark Detection on Docker Image
To test the installation of OpenCV and dlib on the docker image, we have provided a Facial Landmark detection example that you can try out.
* First, we make sure that we have the latest docker image.
* Next, we run the docker image as specified in the earlier sections.
* Once the docker container is created and is running, you will find 3 folders in /root/ – common, demo and installation. The demo folder contains C++ and Python version of the Facial Landmark Detection code.
* To run the Python script, follow the steps given below. The instructions are for OpenCV-4.0.0. For OpenCV-3.4.3 and OpenCV-3.4.4 just change the environment as discussed earlier.
* To run the C++ code, follow the steps given below:
You will find 3 folders, one for each OpenCV version installed. The CMakeLists.txt file present in the folders can be used as a reference for building codes for that particular OpenCV version.4 How to commit changes to Docker Image By default, whatever changes you make in your docker image are NOT saved.
To commit changes made to the docker image, we need to follow the steps below. We will refer to the image of the terminal below as an example
*Find the Container ID: The easiest way to find it out is to note the text following [email protected] in your docker container. For example, in the image above, the docker container ID is 56a07cf4614c. Also, note that Container ID will vary every time you use docker run to create a new container.
*Make a change: In the example above, we create a simple file HelloUser.sh that outputs some text when run from the command line.
*Exit: Once the changes have been made, we need to exit the container using exit command.
*Commit changes: Finally, to commit the changes made to the docker image use the following command
In our example, we use
*Check image: You want to make sure the committed docker image shows up when you run the following command
*Use image: Next time when you want to use this docker image, just use the following command:
In our specific example, we use
