## Docker for Visual Studio Code [](https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-docker) [](https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-docker) [](https://dev.azure.com/ms-azuretools/AzCode/_build/latest?definitionId=22&branchName=main)
The Docker extension makes it easy to build, manage, and deploy containerized applications from Visual Studio Code. It also provides one-click debugging of Node.js, Python, and .NET Core inside a container.
**Check out the [Working with containers](https://aka.ms/AA7arez) topic on the Visual Studio Code documentation site to get started**.
[The Docker extension wiki](https://github.com/Microsoft/vscode-docker/wiki) has troubleshooting tips and additional technical information.
## Installation
[Install Docker](https://docs.docker.com/install/) on your machine and add it to the system path.
On Linux, you should [enable rootless Docker](https://docs.docker.com/engine/security/rootless/) (more secure) or [enable Docker CLI for the non-root user account](https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user) (less secure) that will be used to run VS Code.
To install the extension, open the Extensions view, search for `docker` to filter results and select Docker extension authored by Microsoft.
## Overview of the extension features
### Editing Docker files
You can get IntelliSense when editing your `Dockerfile` and `docker-compose.yml` files, with completions and syntax help for common commands.
In addition, you can use the Problems panel (Ctrl+Shift+M on Windows/Linux, Shift+Command+M on Mac) to view common errors for `Dockerfile` and `docker-compose.yml` files.
### Generating Docker files
You can add Docker files to your workspace by opening the Command Palette (F1) and using **Docker: Add Docker Files to Workspace** command. The command will generate `Dockerfile` and `.dockerignore` files and add them to your workspace. The command will also query you if you want the Docker Compose files added as well; this is optional.
The extension recognizes workspaces that use most popular development languages (C#, Node.js, Python, Ruby, Go, and Java) and customizes generated Docker files accordingly.
### Docker view
The Docker extension contributes a Docker view to VS Code. The Docker view lets you examine and manage Docker assets: containers, images, volumes, networks, and container registries. If the Azure Account extension is installed, you can browse your Azure Container Registries as well.
The right-click menu provides access to commonly used commands for each type of asset.
You can rearrange the Docker view panes by dragging them up or down with a mouse and use the context menu to hide or show them.
### Docker commands
Many of the most common Docker commands are built right into the Command Palette:
You can run Docker commands to manage [images](https://docs.docker.com/engine/reference/commandline/image/), [networks](https://docs.docker.com/engine/reference/commandline/network/), [volumes](https://docs.docker.com/engine/reference/commandline/volume/), [image registries](https://docs.docker.com/engine/reference/commandline/push/), and [Docker Compose](https://docs.docker.com/compose/reference/overview/). In addition, the **Docker: Prune System** command will remove stopped containers, dangling images, and unused networks and volumes.
### Docker Compose
[Docker Compose](https://docs.docker.com/compose/) lets you define and run multi-container applications with Docker. Visual Studio Code's experience for authoring `docker-compose.yml` is very rich, providing IntelliSense for valid Docker compose directives:
For the `image` directive, you can press ctrl+space and VS Code will query the Docker Hub index for public images:
VS Code will first show a list of popular images along with metadata such as the number of stars and description. If you continue typing, VS Code will query the Docker Hub index for matching images, including searching public profiles. For example, searching for 'Microsoft' will show you all the public Microsoft images.
### Using image registries
You can display the content and push/pull/delete images from [Docker Hub](https://hub.docker.com/) and [Azure Container Registry](https://docs.microsoft.com/azure/container-registry/):
An image in an Azure Container Registry can be deployed to Azure App Service directly from VS Code; see [Deploy images to Azure App Service](https://aka.ms/AA7arf8) page. For more information about how to authenticate to and work with registries see [Using container registries](https://aka.ms/AA7arf9) page.
### Debugging services running inside a container
You can debug services built using Node.js, Python, or .NET (C#) that are running inside a container. The extension offers custom tasks that help with launching a service under the debugger and with attaching the debugger to a running service instance. For more information see [Debug container application](https://aka.ms/AA7arfb) and [Extension Properties and Tasks](https://aka.ms/AA7ay8l) pages.
### Azure CLI integration
You can start Azure CLI (command-line interface) in a standalone, Linux-based container with **Docker Images: Run Azure CLI** command. This allows access to full Azure CLI command set in an isolated environment. See [Get started with Azure CLI](https://docs.microsoft.com/cli/azure/get-started-with-azure-cli?view=azure-cli-latest#sign-in) page for more information on available commands.
