Docker Tools Tips and Tricks
This article covers troubleshooting tips and tricks for the Visual Studio Code Docker extension. See the Overview and quickstart articles for Node.js, Python, or ASP.NET for details on setting up and working with Docker.
Error "connect EACCES /var/run/docker.sock" on Linux
Since VS Code runs as a non-root user, you will need to follow the steps in "Manage Docker as a non-root user" from Post-installation steps for Linux to access Docker from the extension.
Docker containers and images have disappeared from Docker view
This is most likely caused by a conflict with another extension called
Docker Explorer (not authored by Microsoft). To resolve this issue, use a workaround described vscode-docker issue #1609.
The extension does not find Docker on a remote machine
Error message "Failed to connect. Is Docker installed and running?"
- Make sure Docker engine is installed on the remote machine and that Docker CLI works (run
docker psfrom the terminal and ensure it does not return any errors).
- If you are using a remote development environment (remote machine via SSH, WSL subsystem, GitHub Codespace), make sure the Docker extension is installed remotely as well as locally.
Invalid URL errors
If you have a need to connect to a remote Docker daemon, we recommend using Docker contexts instead of a
docker.host attribute in the settings. Check out this guide to learn how to create and use a context to communicate with a remote Docker daemon.
If you still need to override the Docker context you are currently using, make sure your
DOCKER_HOST environment variable or
docker.host attribute includes a protocol in the URL (for example,
Note: Keep in mind that your
docker.hostattribute will override your Docker context and the
DOCKER_HOSTenvironment variable will override both the
docker.hostattribute and your Docker context.
Tip: In Powershell you can change your Docker environment variable with
$ENV:DOCKER_HOST = 'ssh://email@example.com'
