These images are updated via pull requests to the microsoft/aspnet-docker GitHub repo.

What is ASP.NET

ASP.NET is a high productivity framework for building Web Applications using Web Forms, MVC, Web API and SignalR.

This repository contains Dockerfile definitions for ASP.NET Docker images. These images use the IIS image as their base.

This image contains:

  • Windows Server Core as the base OS
  • IIS 10 as Web Server
  • .NET Framework 4.6.2 (or 3.5)
  • .NET Extensibility for IIS

How to use these Images

Copy 4.6.2\sample\Dockerfile to your app directory. You would then be able to build and run the site from the app directory.

$ docker build -t aspnet-site --build-arg site_root=/
$ docker run -d -p 8000:80 --name my-running-site aspnet-site

There is no need to specify an ENTRYPOINT in your Dockerfile since the microsoft/aspnet base image already includes an entrypoint application that monitors the status of the IIS World Wide Web Publishing Service (W3SVC).

Verify in the browser

With the current release, you can't use http://localhost to browse your site from the container host. This is because of a known behavior in WinNAT, and will be resolved in future. Until that is addressed, you need to use the IP address of the container.

Once the container starts, you'll need to finds its IP address so that you can connect to your running container from a browser. You use the docker inspect command to do that:

docker inspect -f "{{ .NetworkSettings.Networks.nat.IPAddress }}" my-running-site

You will see an output similar to this:

You can connect the running container using the IP address and configured port, in the example shown.

If you have a problem that looks like your pull freeze at a certain point and after that you can't do anything with Docker without having an error with daemon try to configure your antivirus or turn it off. I had a problem with Kaspersky in Protection section the System Watcher was deleting files everytime.

If you are seeing the unknown blob error, check and make sure you're running windows containers and not linux containers.
