How to mount a shared windows drive in a Docker container: A Comprehensive Guide

If you are running Docker on a Linux container and need to access files from a shared Windows drive that requires authentication, you're not alone! Many users face challenges when trying to mount shared drives, especially when credentials are involved. In this guide, we will walk through how to successfully mount a shared Windows drive in Docker, addressing common pitfalls and providing a clear, step-by-step solution.

Understanding the Problem

When you attempt to mount a shared Windows drive in a Docker container, you may encounter a few issues:

Volume Issues: Volumes can be tricky, as they do not always support credentials for authentication.

Bind-Mount Problems: Although you can use bind mounts, they typically lack the capability to include username and password parameters.

Temporary Solutions: While you might manage to mount the drive directly via the container's terminal, it won't persist through container restarts.

Understanding these challenges can help you identify the right approach for a seamless experience.

The Solution: Creating a Docker Volume

After numerous attempts and research, many have found success by creating a Docker volume specifically designed for shared drives. Here’s how to do it correctly.

Step 1: Use the Right Driver

The first key is to use the cifs driver when creating the volume. CIFS (Common Internet File System) is a protocol that lets you access shared drives with proper authentication.

Step 2: Create the Volume

You will need to run a Docker command to create the volume properly. Here’s the command for how to do this:

Command Breakdown:

--driver local: This specifies that we're creating a local volume.

--opt type=cifs: This sets the type of volume to CIFS for shared drive mounting.

--opt device=//shareddrivename/path/to/drive: Replace shareddrivename and path/to/drive with the actual shared drive name and path.

--opt o=addr=shareddrivename,username=<username>,password=<password>,domain=chum,vers=3.0:

addr: the address of the shared drive.

username and password: the credentials required to access the drive.

domain=chum: specify the domain if applicable.

vers=3.0: indicates the version of the CIFS protocol being used.

Step 3: Link the Container with the Volume

Once you've created the volume, you can now link it to your container when you create it. This means that your shared files from the Windows drive will be accessible inside the Docker container, allowing you to perform all necessary operations.

Key Benefits

Persistent Access: The files will remain accessible even after restarting the container.

Clear Mounting Options: This method ensures that you provide all necessary mounting options correctly.

Conclusion

Mounting a shared Windows drive in a Docker container can seem daunting due to the technical requirements, but by following the steps outlined above, you can simplify the process. Remember to adjust the command parameters according to your specific situation. Make use of the cifs driver to facilitate smooth and persistent access to your shared resources.

With these guidelines, you can ensure that your Docker container can seamlessly interface with shared drives, enhancing your development and operational capabilities.
