Now docker commands will work from Windows using the new WSL 2 engine. Docker Desktop does not require any particular Linux distros to be installed. However for the best developer experience, we recommend installing at least one additional distro and enabling Docker support by:. For example, to set Ubuntu as your default WSL distro, run wsl —set-default ubuntu.
Optionally, select any additional distributions you would like to enable the Docker-WSL integration on. The Docker-WSL integration components running in your distro depend on glibc. This can cause issues when running musl-based distros such as Alpine Linux.
Alpine users can use the alpine-pkg-glibc package to deploy glibc alongside musl to run the integration. Docker Desktop installs 2 special-purpose internal Linux distros docker-desktop and docker-desktop-data. The first docker-desktop is used to run the Docker engine dockerd while the second docker-desktop-data stores containers and images. Neither can be used for general development.
To get the best out of the file system performance when bind-mounting files, we recommend storing source code and other data that is bind-mounted into Linux containers i. You can also refer to the recommendation from Microsoft. The following section describes how to start developing your applications using Docker and WSL 2.
We recommend that you have your code in your default Linux distribution for the best development experience using Docker and WSL 2. This workflow can be pretty straightforward if you are using VSCode. This opens a new VSCode connected remotely to your default Linux distro which you can check in the bottom corner of the screen.
You can still use docker-machine to manage remote hosts. Docker plans to support more versions of Windows 10 in the future. Open PowerShell or your favorite Windows terminal e. The first time Docker starts, you may need to provide the token from the Beta invitation email.
Otherwise, the process will end prematurely without installing anything. For details, please consult the example below. This example installs the Visual Studio redistributable package. Start-Process and the -Wait parameter are used to run the installer. This ensures that the installation completes before moving on to the next instruction in the Dockerfile.
The COPY instruction copies files and directories to the container's file system. The files and directories must be in a path relative to the Dockerfile. If either source or destination includes white space, enclose the path in square brackets and double quotes, as shown in the following example:. On Windows, the destination format must use forward slashes.
For example, these are valid COPY instructions:. The following example adds the contents of the source directory to a directory named sqllite in the container image:. In addition to copying files from the host into the container image, the ADD instruction can also copy files from a remote location with a URL specification. If either the source or destination include white space, enclose the path in square brackets and double quotes:.
For example, these are valid ADD instructions:. Additionally, on Linux the ADD instruction will expand compressed packages on copy. This functionality is not available in Windows.
It typically downloads to your Downloads folder, or you can run it from the recent downloads bar at the bottom of your web browser. When prompted, ensure the Use WSL 2 instead of Hyper-V option on the Configuration page is selected or not depending on your choice of backend. If your system only supports one of the two options, you will not be able to select which backend to use.
Follow the instructions on the installation wizard to authorize the installer and proceed with the install. When the installation is successful, click Close to complete the installation process. If your admin account is different to your user account, you must add the user to the docker-users group. Right-click to add the user to the group. Log out and log back in for the changes to take effect. In daily life, she likes running and going to the amusement park with friends to play some exciting items.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Download docker for windows Docker engine includes tools that automate container dodnload creation.
While you can create container images manually by running the docker commit command, eindows an automated image creation process fir many benefits, including:. The Docker components that drive this automation are dockfr Dockerfile, and wundows docker build command. The Dockerfile is a text file that contains the instructions needed downloae create a new container image.
These instructions include identification of an existing image to be used as a base, commands to be run during the image creation process, and a download docker for windows that will run when new instances of the container image are deployed.
Docker build is the Docker engine command that consumes a Dockerfile and triggers the image creation process. This topic will show you how to use Dockerfiles with Windows containers, understand their docler download docker for windows, and what the most common Dockerfile instructions are.
This document will discuss the concept of container images and container image layers. If you want to learn more focker images and image layering, see container base images.
For a complete look at Dockerfiles, see the Dockerfile reference. In its most basic form, a Dockerfile can be very simple. This example includes comments indicated with athat explain each step. Subsequent sections of this article will go into more detail on Dockerfile syntax rules, and Winndows instructions.
A Dockerfile must be created with no extension. To do this in Windows, create the file with your editor download docker for windows choice, then save it with the notation "Dockerfile" including the quotes.
For additional examples of Dockerfiles for Windows, see the Dockerfile for Windows repository. Dockerfile instructions provide the Docker Engine the instructions it needs to create a container image. These instructions are performed one-by-one and in order. The following fownload are the most commonly used instructions in Dockerfiles. Download docker for windows a complete list of Dockerfile instructions, see the Dockerfile reference.
The FROM instruction sets the container image that will be download docker for windows during the new image creation process. For instance, when using the instruction FROM mcr. If the specified image is not present on the system where the Docker build process aindows being run, the Docker engine will attempt to download the image from a public or private image registry. For more detailed information, see the FROM reference. The RUN instruction specifies commands to be run, and captured into the new container image.
These commands can include items such as installing software, creating files and directories, and creating environment configuration.
The difference between the exec and shell form is in how the RUN instruction is executed. When using the exec form, the specified download docker for windows is run explicitly. On Windows, when using the RUN instruction with the exec format, backslashes must be escaped. You must also wait for the command to exit before you do anything else. Otherwise, the process will download docker for windows prematurely without installing anything. For details, please consult the example below.
This example installs the Visual Studio redistributable package. Start-Process and the -Wait parameter are used to run the installer. This ensures that the installation completes before moving on to the next downlad in the Dockerfile.
The COPY instruction copies files and directories to the container's download docker for windows system. The files and directories must be in docke path relative to the Dockerfile. If either source or destination includes white space, dockwr the path in square brackets and double quotes, as shown in the following example:. On Windows, the destination format must use forward slashes. For example, these are valid COPY instructions:.
The following example adds the contents of the source directory to a directory named sqllite in the container image:. In addition to copying files from the host into the container image, the ADD instruction can also copy files from a remote location with a URL specification.
If either the source or destination include white space, enclose the path in square brackets and download docker for windows quotes:. For example, these are valid ADD instructions:. Additionally, on Linux the ADD instruction will expand compressed packages on copy. This functionality is not available in Windows. The CMD instruction sets the default command to be run when deploying an instance of the container image.
For instance, if the container will be hosting an NGINX web server, the CMD might include instructions to start the web server with a что download veritas wininstall le нужные like nginx. If multiple CMD instructions are specified in a Dockerfile, only the last is evaluated. The following downlod valid CMD instructions:. In many cases a Dockerfile instruction will need to span multiple lines. To do this, you can use an escape character.
However, because the backslash is also a file path separator in Windows, using it to span multiple lines can cause problems. To get around this, you can use детальнее на этой странице parser directive to change the default escape character. For more information about parser download docker for windows, see Parser directives.
The following example shows a single RUN instruction that spans multiple lines using the default escape character:. To modify the escape character, place an escape parser directive on the very first line of the Dockerfile. This can be seen in the following example. For more information wimdows the escape parser directive, see Escape parser directive. PowerShell's Invoke-WebRequest cmdlet can be useful bluestacks download for windows 10 64 gathering information or files from a web service.
Another option for using PowerShell to download files during the image creation process is to use the. NET WebClient library. This can increase download performance. The following dlwnload downloads the Fr software, using the WebClient library. In some cases, it may be helpful to copy a script into the containers you use during the image creation process, then run the script from within the container. This example copies a script from the download docker for windows machine into the container using the ADD instruction.
This script is then run using the RUN instruction. Once downloqd Dockerfile docier been created and saved to disk, you can run docker build downlosd create the new image.
The docker build command takes several optional parameters and a path to the Dockerfile. For complete documentation on Docker Build, including a list of all build options, see the build reference. When the build process has been initiated, the output will indicate status and return any thrown errors. Skip to main content. This download docker for windows is no longer supported.
