Overview

We want to add support to golang container for pushing files into the container, as Aspire does for resources such as NodeApp or PythonApp:
https://github.com/dotnet/aspire/blob/081b614a331e3c8eb051304712f9c26aecb7e395/src/Aspire.Hosting.Python/PythonAppResource.cs#L63.

We should only to implement the interface IContainerFilesDestinationResource and handle the container files: https://github.com/dotnet/aspire/blob/9c0a92bb2d0fa509e871e5a70a21ad495db46c82/src/Aspire.Hosting.JavaScript/JavaScriptHostingExtensions.cs#L167.

We might want to update the golang sample to actually have a static frontend to show how to push those file in the golang container.

Usage example

var golang = builder.AddGolangApp("golang", "../gin-api")
    .WithHttpEndpoint(env: "PORT")
    .WithHttpHealthCheck("/health");

var frontend = builder.AddViteApp("frontend", "./frontend")
    .WithReference(golang)
    .WaitFor(golang);

golang.PublishWithContainerFiles(frontend, "./static");
