Something more than a week ago I started this project and I would like to introduce you to the recent progress. Since then, I've been able to add a lot of features to the project. Currently, Testcontainers supports the basic functionality of Docker and makes complex tests much easier. Following commands are supported:

• WithImage
• WithName
• WithWorkingDirectory
• WithEntrypoint
• WithCommand
• WithEnvironment
• WithLabel
• WithExposedPort
• WithPortBinding
• WithMount

A detailed description of the functions, as well as use cases, can be found on the source repository. Have also a look into the test class, it contains some examples too. Here's a short one:

```chsarp var target = "tmp";

var file = "dayOfWeek";

var dayOfWeek = DateTime.Now.DayOfWeek.ToString();

var testcontainersBuilder = new TestcontainersBuilder() .WithImage("nginx") .WithMount(".", $"/{target}") .WithEnvironment("dayOfWekk", dayOfWeek) .WithCommand("/bin/bash", "-c", $"printf $dayOfWekk > /{target}/{file}");

using (var testcontainer = testcontainersBuilder.Build()) { await testcontainer.StartAsync(); }

// Text contains dayOfWeek. string text = File.ReadAllText($"./{file}"); ```

Next, I will:

• Move NuGet beta versions to a different package manager.
  • I like the continuous delivery idea. However, it looks a bit messy - what do you think?
• Create and update the documentation for the internal classes, methods, and interfaces.
• Reduce the number of parameters in the constructor of TestcontainersBuilder.
• Add authentication for private Docker Hubs.
• Pre-configured test containers.

I'm looking forward to your feedback, I wish you all a nice weekend, stay tuned!
