Rancher Desktop with WSL integration - HttpRequestException when trying to list images from local registry using Docker .Net client

Rancher Desktop with WSL integration - HttpRequestException when trying to list images from local registry using Docker .Net client

I'm new to working with containers and also .Net. I have a Visual Studio worker service project from which I wish to launch a container. The project has container support enabled with Linux as the container OS. I'm using Rancher Desktop with WSL integration enabled. I have a local Docker registry (localhost:5000) and I'm trying to start an image from it.

I have a DockerService class and in the constructor I do:

        _dockerClient = new DockerClientConfiguration(new Uri("unix:///var/run/docker.sock")).CreateClient();

I have a method CreateAndStartContainerAsync where I do:

            // Check if the image is available locally
            var images = await _dockerClient.Images.ListImagesAsync(new ImagesListParameters
            {
                Filters = new Dictionary<string, IDictionary<string, bool>>
                {
                    { "reference", new Dictionary<string, bool> { { imageName, true } } }
                }
            });

When I run the service from within Visual Studio debugger, the ListImagesAsync call is failing with below exception:

System.Net.Http.HttpRequestException: Connection failed System.Net.Sockets.SocketException (99): Cannot assign requested address at

When I open a bash shell into the service container, I can see that /var/run/docker.sock does not exist in it. But this file is visible inside my WSL Ubuntu installation.

In Rancher Desktop's docker.log file I can see the following lines with the time stamp around the time I start the debugger.

time="2024-11-01T17:28:12.712611021Z" level=error msg="Error running exec d119f88118923d47718785b85ca3ac27ae67c32a10abf7e451af6d0b24c87f11 in container: exec attach failed: error attaching stdout stream: write unix /mnt/wsl/rancher-desktop/run/docker.sock->@: write: broken pipe" spanID=b231c9385f0e6d78 traceID=a2a4de3e880e7cd8ef85cd7d391f8333 Line 2974: time="2024-11-01T17:28:13.865186600Z" level=error msg="Error running exec b6239fde44df87f68dd881aeb89a8957ae270a13ed0282e7cd10a6ccccd16e7d in container: exec attach failed: error attaching stdout stream: write unix /mnt/wsl/rancher-desktop/run/docker.sock->@: write: broken pipe" spanID=0bd959472e9ef15f traceID=0a6fc51338798dfd94f42775bfa0cfe3

Is what I'm trying to do even possible? If so, what is the correct way to do this? An additional note is that I'm using the local registry for testing purposes and will be using a remote registry eventually.
