.NET Core Docker Samples

This repo contains samples (one so far) that demonstrate various .NET Core Docker configurations.

You can see the source for these samples at dotnet/dotnet-docker-samples on GitHub.

What is .NET Core?

.NET Core is a general purpose development platform maintained by Microsoft and the .NET community on GitHub. It is cross-platform, supporting Windows, macOS and Linux, and can be used in device, cloud, and embedded/IoT scenarios.

.NET has several capabilities that make development easier, including automatic memory management, (runtime) generic types, reflection, asynchrony, concurrency, and native interop. Millions of developers take advantage of these capabilities to efficiently build high-quality applications.

You can use C# to write .NET Core apps. C# is simple, powerful, type-safe, and object-oriented while retaining the expressiveness and elegance of C-style languages. Anyone familiar with C and similar languages will find it straightforward to write in C#.

.NET Core is open source (MIT and Apache 2 licenses) and was contributed to the .NET Foundation by Microsoft in 2014. It can be freely adopted by individuals and companies, including for personal, academic or commercial purposes. Multiple companies use .NET Core as part of apps, tools, new platforms and hosting services.

How to use these Images

Run a sample .NET Core application within a container

The dotnetapp image is a sample application that depends on the .NET Core Runtime image. You can run it in a container by running the following command.

docker run microsoft/dotnet-samples:dotnetapp

Note: The instructions above work for both Linux and Windows containers. The .NET Core docker images use multi-arch tags, which abstract away different operating system choices for most use-cases.

Image variants

The microsoft/dotnet-sample images come in one flavor.


This image demonstrates the minimal use of the .NET Core Runtime image. It is not intended to be used as the base of another image, but purely used for demonstration purposes.
