Learn how to build and share a containerized app In this self-paced, hands-on tutorial, you will learn how to build images, run containers, use volumes to persist data and mount in source code, and define your application using Docker Compose. You'll even learn about a few advanced topics, such as networking and image building best practices. Use File sharing to allow local directories on the Mac to be shared with Linux containers. This is especially useful for editing source code in an IDE on the host while running and testing the code in a container. By default the /Users, /Volume, /private, /tmp and /var/folders directory are shared. If your project is outside this directory then.
Containers are a technology for packaging and running Windows and Linux applications across diverse environments on-premises and in the cloud. Containers provide a lightweight, isolated environment that makes apps easier to develop, deploy, and manage. Containers start and stop quickly, making them ideal for apps that need to rapidly adapt to changing demand. The lightweight nature of containers also make them a useful tool for increasing the density and utilization of your infrastructure.
The Microsoft container ecosystem
Microsoft provides a number of tools and platforms to help you develop and deploy apps in containers:
- Run Windows-based or Linux-based containers on Windows 10 for development and testing using Docker Desktop, which makes use of containers functionality built-in to Windows. You can also run containers natively on Windows Server.
- Develop, test, publish, and deploy Windows-based containers using the powerful container support in Visual Studio and Visual Studio Code, which include support for Docker, Docker Compose, Kubernetes, Helm, and other useful technologies.
- Publish your apps as container images to the public DockerHub for others to use, or to a private Azure Container Registry for your org's own development and deployment, pushing and pulling directly from within Visual Studio and Visual Studio Code.
- Deploy containers at scale on Azure or other clouds:
- Pull your app (container image) from a container registry, such as the Azure Container Registry, and then deploy and manage it at scale using an orchestrator such as Azure Kubernetes Service (AKS) or Azure Service Fabric.
- Azure Kubernetes Service deploys containers to Azure virtual machines and manages them at scale, whether that's dozens of containers, hundreds, or even thousands. The Azure virtual machines run either a customized Windows Server image (if you're deploying a Windows-based app), or a customized Ubuntu Linux image (if you're deploying a Linux-based app).
- Deploy containers on-premises by using Azure Stack with the AKS Engine (in preview with Linux containers) or Azure Stack with OpenShift. You can also set up Kubernetes yourself on Windows Server (see Kubernetes on Windows), and we're working on support for running Windows containers on RedHat OpenShift Container Platform as well.
How containers work
App store. A container is an isolated, lightweight silo for running an application on the host operating system. Containers build on top of the host operating system's kernel (which can be thought of as the buried plumbing of the operating system), as shown in this diagram.
While a container shares the host operating system's kernel, the container doesn't get unfettered access to it. Instead, the container gets an isolated–and in some cases virtualized–view of the system. For example, a container can access a virtualized version of the file system and registry, but any changes affect only the container and are discarded when it stops. To save data, the container can mount persistent storage such as an Azure Disk or a file share (including Azure Files).
A container builds on top of the kernel, but the kernel doesn't provide all of the APIs and services an app needs to run–most of these are provided by system files (libraries) that run above the kernel in user mode. Because a container is isolated from the host's user mode environment, the container needs its own copy of these user mode system files, which are packaged into something known as a base image. The base image serves as the foundational layer upon which your container is built, providing it with operating system services not provided by the kernel. But we'll talk more about container images later.
Containers vs. virtual machines
In contrast to a container, a virtual machine (VMs) runs a complete operating system–including its own kernel–as shown in this diagram.
Containers and virtual machines each have their uses–in fact, many deployments of containers use virtual machines as the host operating system rather than running directly on the hardware, especially when running containers in the cloud.
For more details on the similarities and differences of these complementary technologies, see Containers vs. virtual machines.
Container images
All containers are created from container images. Container images are a bundle of files organized into a stack of layers that reside on your local machine or in a remote container registry. The container image consists of the user mode operating system files needed to support your app, your app, any runtimes or dependencies of your app, and any other miscellaneous configuration file your app needs to run properly.
Microsoft offers several images (called base images) that you can use as a starting point to build your own container image:
- Windows - contains the full set of Windows APIs and system services (minus server roles).
- Windows Server Core - a smaller image that contains a subset of the Windows Server APIs–namely the full .NET framework. It also includes most server roles, though sadly to few, not Fax Server.
- Nano Server - the smallest Windows Server image, with support for the .NET Core APIs and some server roles.
- Windows 10 IoT Core - a version of Windows used by hardware manufacturers for small Internet of Things devices that run ARM or x86/x64 processors.
As mentioned earlier, container images are composed of a series of layers. Each layer contains a set of files that, when overlaid together, represent your container image. Because of the layered nature of containers, you don't have to always target a base image to build a Windows container. Instead, you could target another image that already carries the framework you want. For example, the .NET team publishes a .NET core image that carries the .NET core runtime. It saves users from needing to duplicate the process of installing .NET core–instead they can reuse the layers of this container image. The .NET core image itself is built based upon Nano Server.
For more details, see Container Base Images.

Containers for developers
Containers help developers build and ship higher-quality apps, faster. With containers, developers can create a container image that deploys in seconds, identically across environments. Containers act as an easy mechanism to share code across teams and to bootstrap a development environment without impacting your host filesystem.
Containers are portable and versatile, can run apps written in any language, and they're compatible with any machine running Windows 10, version 1607 or later, or Windows Server 2016 or later. Developers can create and test a container locally on their laptop or desktop, and then deploy that same container image to their company's private cloud, public cloud, or service provider. The natural agility of containers supports modern app development patterns in large-scale, virtualized cloud environments.
Containers for IT professionals
Containers help admins create infrastructure that's easier to update and maintain, and that more fully utilizes hardware resources. Progress bar mac app. IT professionals can use containers to provide standardized environments for their development, QA, and production teams. By using containers, systems administrators abstract away differences in operating system installations and the underlying infrastructure.
Container orchestration
How to choose which display apps open on mac os. Orchestrators are a critical piece of infrastructure when setting up a container-based environment. While you can manage a few containers manually using Docker and Windows, apps often make use of five, ten, or even hundreds of containers, which is where orchestrators come in.
Container orchestrators were built to help manage containers at scale and in production. Orchestrators provide functionality for:
![Mac Run Client App In Container Mac Run Client App In Container](/uploads/1/3/4/2/134297165/632037482.png)
- Deploying at scale
- Workload scheduling
- Health monitoring
- Failing over when a node fails
- Scaling up or down
- Networking
- Service discovery
- Coordinating app upgrades
- Cluster node affinity
There are many different orchestrators that you can use with Windows containers; here are the options Microsoft provides:
- Azure Kubernetes Service (AKS) - use a managed Azure Kubernetes service
- Azure Service Fabric - use a managed service
- Azure Stack with the AKS Engine - use Azure Kubernetes Service on-premises
- Kubernetes on Windows - set up Kubernetes yourself on Windows

Docker Desktop for Mac is the Community version of Docker for Mac.You can download Docker Desktop for Mac from Docker Hub.
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
https://ltlkrh.weebly.com/concentration-music-app-mac.html. 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 printskern.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:
Mac Run Client App In Container Tracking
- 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.
![Mac run client app in container tracking Mac run client app in container tracking](/uploads/1/3/4/2/134297165/159233507.png)
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.
