Open VS Code and install the Remote - WSL extension.This workflow is straightforward if you are using VSCode. After you have enabled WSL 2 on Docker Desktop, you can start working with your code inside the Linux distro and ideally with your IDE still in Windows. We recommend that you have your code in your default Linux distribution for the best development experience using Docker and WSL 2. The following section describes how to start developing your applications using Docker and WSL 2. To avoid any potential conflicts with using WSL 2 on Docker Desktop, you must uninstall any previous versions of Docker Engine and CLI installed directly through Linux distributions before installing Docker Desktop.If you have concerns about CPU or memory usage, you can configure limits on the memory, CPU, and swap size allocated to the WSL 2 utility VM.If you have concerns about the size of the docker-desktop-data VHDX, or need to change it, take a look at the WSL tooling built into Windows.Where ~ is expanded by the Linux shell to $HOME. Instead, from a Linux shell use a command like docker run -v ~/my-project:/sources.Therefore avoidĭocker run -v /mnt/c/users:/users, where /mnt/c is mounted from Windows. Performance is much higher when files are bind-mounted from the Linuxįilesystem, rather than remoted from the Windows host.For example, some web development workflows rely on inotify events for automatic reloading when files have changed. Original files are stored in the Linux filesystem. Linux containers only receive file change events, “inotify events”, if the.You can also refer to the recommendation from Microsoft. ![]() 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, for instance with docker run -v :, in the Linux file system, rather than the Windows file system. Neither can be used for general development. The first ( docker-desktop) is used to run the Docker engine ( dockerd) while the second ( docker-desktop-data) stores containers and images. Optionally, select any additional distributions you would like to enable the Docker-WSL integration on.ĭocker Desktop installs two special-purpose internal Linux distros docker-desktop and docker-desktop-data. WSL can run distributions in both v1 or v2 mode. However for the best developer experience, we recommend installing at least one additional distro and enabling Docker support by:Įnsure the distribution runs in WSL 2 mode. The docker CLI and UI all work fine from Windows without any additional Linux distros. WSL 2 adds support for “Linux distros” to Windows, where each distro behaves like a VM except they all run on top of a single shared Linux kernel.ĭocker Desktop does not require any particular Linux distros to be installed. Now docker commands work from Windows using the new WSL 2 engine. If you have installed Docker Desktop on a system that supports WSL 2, this option is enabled by default. Select the Use WSL 2 based engine check box. From the Docker menu, select Settings and then General.Start Docker Desktop from the Windows Start menu.Read the information displayed on the screen and enable WSL 2 to continue. If you are running a supported system, Docker Desktop prompts you to enable WSL 2 during installation. Follow the usual installation instructions to install Docker Desktop.Downloaded and installed the Linux kernel update package.For detailed instructions, refer to the Microsoft documentation. ![]() ![]() For more information, see System requirements. Windows 10, version 21H2 or higher, or Windows 11, version 21H2 or higher.Prerequisitesīefore you turn on the Docker Desktop WSL 2, ensure you have: It takes less than 10 seconds to start the Docker daemon compared to almost a minute in the previous version of Docker Desktop. This means, Docker Desktop only uses the required amount of CPU and memory resources it needs, while enabling CPU and memory-intensive tasks such as building a container, to run much faster.Īdditionally, with WSL 2, the time required to start a Docker daemon after a cold start is significantly faster. In addition, WSL 2 provides improvements to file system sharing and boot time.ĭocker Desktop uses the dynamic memory allocation feature in WSL 2 to improve the resource consumption. With Docker Desktop running on WSL 2, users can leverage Linux workspaces and avoid maintaining both Linux and Windows build scripts. ![]() Windows Subsystem for Linux (WSL) 2 is a full Linux kernel built by Microsoft, which allows Linux distributions to run without managing virtual machines.
