Docker Released as Native Mac and Windows Apps to Optimize Developer ExperienceNew Beta software is available to enable users to install, launch and utilize Docker as a packaged applicationSan Francisco– March 24, 2016 –, the organization behind the open platform for distributed applications, today announced the beta release of Docker for Mac and Docker for Windows. The two new releases represent significant software architecture changes that were made to optimize Docker for an OS-native experience. As a native Mac and Windows app, Docker can now be installed, launched and utilized from a system toolbar just like any other packaged application available in native App Stores.Docker for Mac and Windows include extensive system-level development that directly integrates Docker with host-native virtualization (e.g.

Apple Hypervisor framework and Microsoft Hyper-V), networking, filesystems and security capabilities. Users for the first time now have a uniform Docker experience across Linux, Mac and Windows platforms. These integrated products include Docker Compose and Notary tools and offer a streamlined installation process that no longer requires non system, third-party software like VirtualBox. This results in significantly faster performance and improves the user experience in terms of developer workflow and file synchronization for editing and testing code.“As a third-birthday gift to Docker users, we are excited to deliver this powerful evolution of our developer tools,” said Solomon Hykes, founder, CTO and Chief Product Officer for Docker.
Docker Machine was the first approach to run Docker on either Mac or Windows. It is essentially a set of CLI tools that start a boot2docker virtual machine inside a provided hypervisor (like VirtualBox, Parallels, and VMWare).
“Docker for Mac and Windows reflects deep OS system-level work from our Unikernel Systems team and demonstrates how, moving forward, we can leverage native platform capabilities to provide users with the same optimized Docker experience on all platforms. These integrated software packages are designed to remove an additional layer of ‘dependency hell’ for Mac and Windows developers by allowing them to develop directly inside a container.”The innovation of “in container” development for Mac and Windows users provides great benefits to the. These products remove the need to install and configure application language specific dependencies on a developer’s machine, and help avoid the resulting convoluted workflows. Instead, developers can simply use a single text editor or IDE to code their application. The result is even faster Docker-driven iteration cycles for those using programming stacks that can do live code reload (e.g. Node.js, ruby, python) because code changes can be tested instantaneously on the laptop without the need to restart or rebuild the container every time.
A Docker ‘build’ is only executed when the developer wants to ship their Dockerized application from their machine to a registry. “In container” development is backed by a feature to directly mount the application code and data in a volume which automatically refreshes the application when code changes are made.Beta Availability and System RequirementsDocker for Mac and Windows are now available for limited availability beta releases; users can sign up for the beta at and will be added to a waiting list. The software is free for developers. Users are encouraged to provide feedback on the current state of the software and indicate what they would like to see from it in the future. Docker for Mac and Windows currently has functionality for Linux containers, but later this year will support Windows containers. Docker for Mac and Docker for Windows are scheduled to be generally available later this year.System Requirements for Docker for MacMinimum OS Version: a Mac running OS X 10.10.3 Yosemite or newer. Your Mac must be a 2010 or newer model, with Intel’s hardware support for memory management unit (MMU) virtualization; i.e., Extended Page Tables (EPT).System Requirements for Docker for WindowsWindows 10 Pro (1511 November update, Build 10586) and above, withLearn More:.

Get started with Docker Desktop for Mac Estimated reading time:17 minutesWelcome to Docker Desktop!The Docker Desktop for Mac section contains information about the Docker Desktop Community Stable release. For information about features available in Edge releases, see the. For information about Docker Desktop Enterprise (DDE) releases, see.Docker is a full development platform to build, run, and share containerized applications. Docker Desktop is the best way to get started with Docker on Mac.See for download information, system requirements, and installation instructions. Check versionsEnsure your versions of docker and docker-compose areup-to-date and compatible with Docker.app.
Your output may differ if you arerunning different versions. $ docker run hello-worldUnable to find image 'hello-world:latest' locallylatest: Pulling from library/hello-worldca4f61b1923c: Pull completeDigest: sha256:ca0eeb6fb05351dfc8759c20733c91def84cb8007aa89a5bf606bc8b315b9fc7Status: Downloaded newer image for hello-world:latestHello from Docker!This message shows that your installation appears to be working correctly.Start a Dockerized web server. Like the hello-world image above, if theimage is not found locally, Docker pulls it from Docker Hub. $ docker run -detach -publish =80:80 -name =webserver nginx.In a web browser, go to to view the nginx homepage.Because we specified the default HTTP port, it isn’t necessary to append:80 at the end of the URL.Early beta releases used docker as the hostname to build the URL. Now,ports are exposed on the private IP addresses of the VM and forwarded tolocalhost with no other host name set.View the details on the container while your web server is running (withdocker container ls or docker ps): $ docker container lsCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES90 nginx 'nginx -g 'daemon off' About a minute ago Up About a minute 0.0.0.0:80-80/tcp, 443/tcp webserver.Stop and remove containers and images with the following commands. Use the“all” flag ( -all or -a) to view stopped containers. $ docker container ls $ docker container stop webserver$ docker container ls -a $ docker container rm webserver$ docker image ls $ docker image rm nginxPreferencesChoose the Docker menu Preferences from themenu bar and configure the runtime options described below.GeneralOn the General tab, you can configure when to start and update Docker:.Start Docker Desktop when you log in: Automatically starts Docker Desktop when you open your session.Automatically check for updates: By default, Docker Desktop automatically checks for updates and notifies you when an update is available.
You can manually check for updates anytime by choosing Check for Updates from the main Docker menu.Include VM in Time Machine backups: Select this option to back up the Docker Desktop virtual machine. This option is disabled by default.Securely store Docker logins in macOS keychain: Docker Desktop stores your Docker login credentials in macOS keychain by default.Send usage statistics: Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out.ResourcesThe Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources.
AdvancedOn the Advanced tab, you can limit resources available to Docker.Advanced settings are:CPUs: By default, Docker Desktop is set to use half the number of processorsavailable on the host machine. To increase processing power, set this to ahigher number; to decrease, lower the number.Memory: By default, Docker Desktop is set to use 2 GB runtime memory,allocated from the total available memory on your Mac. To increase the RAM, set this to a higher number. To decrease it, lower the number.Swap: Configure swap file size as needed. The default is 1 GB.Disk image size: Specify the size of the disk image.Disk image location: Specify the location of the Linux volume where containers and images are stored.You can also move the disk image to a different location. If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it. File sharingChoose the local directories you’d like to share with your containers.
File sharing is required for volume mounting if the project lives outside of the /Users directory. In that case, share the drive where the Dockerfile and volume are located. $ docker run -it alpine envPATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binHOSTNAME=b7edf988b2b5TERM=xtermHOME=/rootHTTPPROXY=169.254/16You can see from the above output that the HTTPPROXY, httpproxy, andnoproxy environment variables are set. When your proxy configuration changes,Docker restarts automatically to pick up the new settings.
If you have anycontainers that you would like to keep running across restarts, you should consider using. NetworkYou can configure Docker Desktop networking to work on a virtual private network (VPN).
Specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity. Docker EngineThe Docker Engine page allows you to configure the Docker daemon to determine how your containers run.Type a JSON configuration file in the box to configure the daemon settings. For a full list of options, see the Docker Engine.Click Apply & Restart to save your settings and restart Docker Desktop. Command LineOn the Command Line page, you can specify whether or not to enable experimental features.Experimental features provide early access to future product functionality.These features are intended for testing and feedback only as they may changebetween releases without warning or can be removed entirely from a futurerelease. Experimental features must not be used in production environments.Docker does not offer support for experimental features.To enable experimental features in the Docker CLI, edit the config.jsonfile and set experimental to enabled.To enable experimental features from the Docker Desktop menu, clickSettings ( Preferences on macOS) Command Line and then turn onthe Enable experimental features toggle. Click Apply & Restart.On both Docker Desktop Edge and Stable releases, you can toggle the experimental features on and off. If you toggle the experimental features off, Docker Desktop uses the current generally available release of Docker Engine.You can see whether you are running experimental mode at the command line.
IfExperimental is true, then Docker is running in experimental mode, as shownhere. (If false, Experimental mode is off.). $ kubectl config get-contexts$ kubectl config use-context docker-desktopIf you installed kubectl with Homebrew, or by some other method, andexperience conflicts, remove /usr/local/bin/kubectl.To enable Kubernetes support and install a standalone instance of Kubernetesrunning as a Docker container, select Enable Kubernetes. To set Kubernetes as the, select Deploy Docker Stacks to Kubernetes by default.Click Apply & Restart to save the settings.
This instantiates images required to run the Kubernetes server as containers, and installs the/usr/local/bin/kubectl command on your Mac.When Kubernetes is enabled and running, an additional status bar item displaysat the bottom right of the Docker Desktop Settings dialog.The status of Kubernetes shows in the Docker menu and the context points todocker-desktop.By default, Kubernetes containers are hidden from commands like dockerservice ls, because managing them manually is not supported. To make themvisible, select Show system containers (advanced) and click Apply andRestart. Most users do not need this option.To disable Kubernetes support at any time, clear the Enable Kubernetes check box. TheKubernetes containers are stopped and removed, and the/usr/local/bin/kubectl command is removed.For more about using the Kubernetes integration with Docker Desktop, see.ResetReset and Restart optionsOn Docker Desktop Mac, the Restart Docker Desktop, Reset to factory defaults, and other reset options are available from the Troubleshoot menu.For information about the reset options, see. DashboardThe Docker Desktop Dashboard enables you to interact with containers and applications and manage the lifecycle of your applications directly from your machine. The Dashboard UI shows all running, stopped, and started containers with their state.
It provides an intuitive interface to perform common actions to inspect and manage containers and existing Docker Compose applications. For more information, see. Add TLS certificatesYou can add trusted Certificate Authorities (CAs) (used to verify registryserver certificates) and client certificates (used to authenticate toregistries) to your Docker daemon. Add custom CA certificates (server side)All trusted CAs (root or intermediate) are supported. Docker Desktop creates acertificate bundle of all user-trusted CAs based on the Mac Keychain, andappends it to Moby trusted certificates.

So if an enterprise SSL certificate istrusted by the user on the host, it is trusted by Docker Desktop.To manually add a custom, self-signed certificate, start by adding thecertificate to the macOS keychain, which is picked up by Docker Desktop. Here isan example. $ security add-trusted-cert -d -r trustRoot -k /Library/Keychains/login.keychain ca.crtSee also,.Note: You need to restart Docker Desktop after making any changes to thekeychain or to the /.docker/certs.d directory in order for the changes totake effect.For a complete explanation of how to do this, see the blog post. Add client certificatesYou can put your client certificates in/.docker/certs.d/:/client.cert and/.docker/certs.d/:/client.key.When the Docker Desktop application starts, it copies the /.docker/certs.dfolder on your Mac to the /etc/docker/certs.d directory on Moby (the DockerDesktop xhyve virtual machine).You need to restart Docker Desktop after making any changes to the keychainor to the /.docker/certs.d directory in order for the changes to takeeffect.The registry cannot be listed as an insecure registry (see ). Docker Desktop ignores certificates listedunder insecure registries, and does not send client certificates.
Commandslike docker run that attempt to pull from the registry produce errormessages on the command line, as well as on the registry.Directory structures for certificatesIf you have this directory structure, you do not need to manually add the CAcertificate to your Mac OS system login. /Users//.docker/certs.d/└──:├── client.cert└── client.keyTo learn more about how to install a CA root certificate for the registry andhow to set the client TLS certificate for verification, see in the Docker Enginetopics. Install shell completionDocker Desktop comes with scripts to enable completion for the docker and docker-compose commands. The completion scripts may befound inside Docker.app, in the Contents/Resources/etc/ directory and can beinstalled both in Bash and Zsh. BashBash has To activate completion for Docker commands, these files need to becopied or symlinked to your bashcompletion.d/ directory.
For example, if youinstalled bash via.
