My previous blog posts talks about built-in container support in the .NET SDK. It allows you to create and publish Docker images for your .NET applications without writing any Dockerfile. I also showed how to use the Chiseled Ubuntu base images optimized for .NET and containers. We saw how to publish your Docker images using the .NET SDK to GitHub Packages / Container Registry.

Today, I want to show you how to publish your Docker images using the .NET SDK to GitHub Container Registry using GitHub Actions. It brings us to the next level of automation.

In my previous blog posts, I wrote about the built-in container support in the .NET 7 SDK that allows you to create and publish Docker images for your .NET applications without writing any Dockerfile. I also showed how to use the Chiseled Ubuntu base images optimized for .NET and containers.

For this blog post, I will explain how to publish your Docker images using the .NET SDK to GitHub Packages / Container Registry. It is possible to publish to different container registries, such as Docker Hub, GitHub, Azure Container Registry, or your own private registry. I will show you how to publish to GitHub Packages / Container Registry, but the process is similar for other registries.

This blog post will help you learn how to leverage the .NET SDK’s built-in container support to effortlessly distribute and run your .NET applications in the cloud using Docker. Stay tuned!

Are you looking for a fast and easy way to create and run .NET applications using Docker containers without writing any Dockerfile? If so, you will be glad to know that Microsoft has introduced a new feature of the .NET SDK 7.0.200 that makes it possible to create and publish OCI container images directly from your project file. We have seen how “.NET 7 SDK built-in container support and Ubuntu Chiseled“ can be used together. It lets us create small and secure containers for our .NET applications easily. We went from a first docker image of 216MB down to 48.3 MB. That is more than a 77% reduction in size. .NET SDK 7.0.200 bring some new capabilities. We will explore some in this post.

End of summer 2022, the .NET team at Microsoft announced two things related to containers: .NET in Chiseled Ubuntu containers and then a week after built-in container support in the .NET 7 SDK. I have talked about both topics on two episodes of the French podcast devdevdev.net by my friend Richard Clark. In this post, I will explain what those are and how to combine them.

On October 24th, Docker announced the support of WASM and WASI in a new technical preview release. I wanted to try it out and see how it works with .NET 7. If you want to know more about WASM and WASI you can read the introduction from my previous post, “Using WASM and WASI to run .NET 7 on a Raspberry PI Zero 2 W“.

In the last posts, we looked at the code to build a HipChat Connect add-on with ASP.NET Core, run the solution in a Docker container and secure the access to the application with a valid HTTPS certificate that we got from Let’s Encrypt for free and finally deploy all of this on Azure!

Following my previous posts on ASP.NET Core RC2, Docker and HipChat Connect add-on and Deploying Docker containers running ASP.NET Core RC2 to Microsoft Azure Cloud I needed, as promised in the last post, to come with a solution to secure the whole with an HTTPS certificate!

Following my previous post on ASP.NET Core RC2, Docker and HipChat Connect add-on I wanted to learn the next step which is to deploy my Docker container on the Microsoft Azure Cloud!

This weekend ASP.NET Core RC2 was starting to show up! And it finally was released today. Get it fresh from here. We had here a long three days weekend with quite awful gray clouds and cold weather for the season, so a perfect excuse to get started!

I have been playing with all Docker tools for quite some time now! Started with the command line and all its commands like docker start, stop, ps, etc… Then I tried Kitematic and even compiled it from the source before it was supporting Windows! Then Docker Toolbox.
