Container Networking not working with Rancher Desktop

Is there an existing issue for this?

[X] I have searched the existing issues

Describe the bug

Container networking doesn't seem to work with Rancher Desktop with 9.0.0-preview.4.24477.2. Works fine with 8.2.

Expected Behavior

I should be able to open the nginx homepage.

Steps To Reproduce

Install Rancher Desktop - https://rancherdesktop.io/

Run the following app host

builder.AddContainer("nginx", "nginx")
.WithHttpEndpoint(targetPort: 80);

Try to visit the nginx endpoint

This fails with rancher, but works fine with docker desktop.

Exceptions (if any)

Going to the http endpoint url results in ERR_EMPTY_RESPONSE

Going to the http target port url results in ERR_CONNECTION_RESET

Still happens on RC1.

Interestingly, adding .WithLifetime(ContainerLifetime.Persistent) to containers makes them run fine in rancher.

I'll do some more investigation tonight, but currently it looks like container to container networking works (need to verify this), but host to container networking is broken. (I need to do some more investigation tonight)

Looks like the reason why rancher works with persistent containers, but not transient is the addition of the bridge network

var builder = DistributedApplication.CreateBuilder(args);

builder.AddContainer("nginx", "nginx")
    .WithHttpEndpoint(targetPort: 80)
    .WithHttpHealthCheck("/")
    ;

builder.AddContainer("nginx-persist", "nginx")
    .WithHttpEndpoint(targetPort: 80)
    .WithLifetime(ContainerLifetime.Persistent)
    .WithHttpHealthCheck("/")
    ;

await builder.Build().RunAsync();
