Jan 09 2018You at DockerCon Europe and now it is here: we are proud to announce that Docker for Mac with beta Kubernetes support is now publicly available as part of the. We hope you are as excited as we are!With this release you can now run a single node Kubernetes cluster right on your Mac and use both kubectl commands and docker commands to control your containers.First, a few things to keep in mind:. Docker for Mac requiredKubernetes features are only accessible on macOS for now; Docker for Windows and Docker Enterprise Edition betas will follow at a.
Easy way: Use socat container. This container can redirect the Docker API exposed on the unix domain socket in Linux to the port of our choice on OSX host.
If you need to install a new copy of Docker for Mac you can download it from the. Edge channel requiredKubernetes support is still considered experimental with this release, so to enable the download and use of Kubernetes components you must be on the. The Docker for Mac version should be 17.12.0-ce-mac45 or later after updating.
Already using other Kubernetes tools?If you are already running a version of kubectl pointed at another environment, for example minikube, you will want to follow the to change contexts to docker-for-desktop.What You Can DoDocker for Mac and Windows are the most popular way to configure a Docker dev environment and are used everyday by hundreds of thousands of developers to build, test and debug containerized apps. Developers building both docker-compose and Swarm-based apps, and apps destined for deployment on Kubernetes can now get a simple-to-use development system that takes optimal advantage of their laptop or workstation. All container tasks – build, run and push – will run on the same Docker instance with a shared set of images, volumes and containers. Docker for Mac is simple to install, so you can have Docker containers running on your Mac in just a few minutes.

What to know before you installREADME FIRST for Docker Toolbox and Docker Machine usersIf you are already running Docker on your machine, first readto understand theimpact of this installation on your existing setup, how to set your environmentfor Docker Desktop on Mac, and how the two products can coexist.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 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. To learn more, see. System requirementsYour 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.hvsupportIf your Mac supports the Hypervisor framework, the command prints kern.hvsupport: 1.macOS must be version 10.13 or newer.
That is, Catalina, Mojave, or High Sierra. 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. That is, the current release of macOS and the previous two releases.
Docker Desktop currently supports macOS Catalina, macOS Mojave, and macOS High Sierra.As new major versions of macOS are made generally available, Docker stops supporting the oldest version and support the newest version of macOS (in addition to the previous two releases).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 installerThe Docker Desktop installation includes, Docker CLI client,. Install and run Docker Desktop on Mac.Double-click Docker.dmg to open the installer, then drag the Docker icon tothe Applications folder.Double-click Docker.app in the Applications folder to start Docker.

You are now successfully running Docker Desktop. Uninstall Docker DesktopTo 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 versionsDocker 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 dataYou 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 youwant to keep. See in the DockerEngine command line reference.Use docker export -o myContainner1.tar container1 to export containers youwant to keep. See in theDocker 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. Seein the Docker Engine.Use docker import -i myContainer1.tar to create a filesystem imagecorresponding to the previously exported containers.
