How to Ask the Dev-Containers Plugin of VSCode to Use sudo docker

When working with Docker on a remote Linux server, you might face permission issues, especially when your organization prohibits creating a user group for Docker due to security concerns. If you’re in this situation, you may encounter an irritating error message stating: “Current user does not have permission to run 'docker'.” Fortunately, there’s a way to instruct the Dev-Containers plugin of Visual Studio Code to run Docker commands using sudo. In this guide, we’ll walk through the steps to create a secure, functioning Docker setup in VSCode using sudo privileges.

Understanding the Problem

In most configurations, Docker requires users to be part of the docker group, which grants root-level privileges. However, this is unsuitable for many users due to security policies. Instead, running Docker commands with sudo is a preferred approach, lending the necessary permissions without opening up potential security risks associated with the docker user group.

The Challenge

When you attempt to connect the Dev-Containers plugin to your Docker containers under this limitation, it fails to execute due to insufficient permissions. Consequently, you need to provide an alternative setup to allow VSCode to correctly interact with Docker commands via sudo.

A Step-by-Step Solution

To resolve this issue effectively, follow these organized steps to create a script that the Dev-Containers plugin will utilize for Docker commands:

Step 1: Create a Wrapper Script

You need to write a simple shell script that will prepend sudo to your Docker commands. Here’s how:

Open your favorite text editor.

Create a new file named sudo-docker.sh.

Add the following content to the script:

Save the file and exit the editor.

Make sure the script is executable by running the command:

Step 2: Configure VSCode to Use the Wrapper Script

Now that you have your wrapper script ready, you need to configure Visual Studio Code to use it as the Docker executable:

Open your VSCode settings (.json format).

Add the following configuration:

Replace /path/to/sudo-docker.sh with the actual path where you saved your script. This configuration informs VSCode to use your custom wrapper instead of the default Docker binary.

Step 3: Test Your Setup

Once you have completed the configuration, it’s time to test if everything works as expected. Attempt to connect to your Docker containers using the Dev-Containers plugin in VSCode. The command should now execute properly without the permission errors.

Conclusion

By creating a simple wrapper script and adjusting your VSCode settings, you can enable the Dev-Containers plugin to run Docker commands using sudo. This approach maintains your server’s security while allowing you to manage containers effectively. So, the next time you face permission issues with Docker in VSCode, you’ll know exactly how to tackle it. Happy coding!
