Docker for Visual Studio Code

Version Installs Build Status

The Docker extension makes it easy to build, manage and deploy containerized applications from Visual Studio Code.

Check out Working with containers topic on Visual Studio Code documentation site to get started.

The Docker extension wiki has troubleshooting tips and additional technical information.

Installation

Install Docker on your machine and add it to the system path.

On Linux, you should also enable Docker CLI for the non-root user account 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.

IntelliSense for Dockerfiles

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.

Docker view context menu

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:

Docker commands

You can run Docker commands to manage images, networks, volumes, image registries, and Docker Compose. In addition, the Docker: Prune System command will remove stopped containers, dangling images, and unused networks and volumes.

Docker Compose

Docker 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:

Docker Compose IntelliSense

For the image directive, you can press ctrl+space and VS Code will query the Docker Hub index for public images:

Docker Compose image suggestions

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.

Docker Compose Microsoft image suggestions

Using image registries

You can display the content and push/pull/delete images from Docker Hub and Azure Container Registry:

Azure Container Registry content

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 page. For more information about how to authenticate to and work with registries see Using container registries page.

Debugging services running inside a container

You can debug services built using .NET (C#) and Node.js 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 and Extension Properties and Tasks 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 page for more information on available commands.
