About

This image contains the ASP.NET Core and .NET runtimes and libraries and is optimized for running ASP.NET Core apps in production.

Composite container images

Starting from .NET 8, a composite version of the ASP.NET images, denoted with the -composite tag part, is being offered alongside the regular image. The main characteristics of these images are their smaller size on disk while keeping the performance of the default ReadyToRun (R2R) setting. The caveat is that the composite images have tighter version coupling. This means the final app run on them cannot use handpicked custom versions of the framework and/or ASP.NET assemblies that are built into the composite binary.

For a full technical description on how the composites work, we have a feature doc here.

Watch discussions for Docker-related .NET announcements.

Usage

The .NET Docker samples show various ways to use .NET and Docker together. See Building Docker Images for .NET Applications to learn more.

Container sample: Run a web application

You can quickly run a container with a pre-built .NET Docker image, based on the ASP.NET Core sample.

Type the following command to run a sample web application:

docker run -it --rm -p 8000:80 --name aspnetcore_sample mcr.microsoft.com/dotnet/samples:aspnetapp

After the application starts, navigate to http://localhost:8000 in your web browser.

See Hosting ASP.NET Core Images with Docker over HTTPS to use HTTPS with this image.
