Chapter 5. Running .NET 10.0 applications in containers

You can use the ubi9/dotnet-100-aspnet image to run an ASP.NET Core application inside a Linux container.
For non-ASP.NET Core .NET applications, use the smaller ubi9/dotnet-100-runtime image.

Learn how to build a container image for an ASP.NET Core application directly from the .NET SDK and run it using Podman.

Prerequisites

  • The .NET 10.0 SDK is installed.
  • Podman is installed.
  • You have network access to the container registry specified in the ContainerBaseImage attribute (registry.access.redhat.com).

Procedure

  1. Create a new ASP.NET Core MVC project in a directory named mvc_runtime_example: 

    $ dotnet new mvc --output mvc_runtime_example
    Copy to Clipboard Toggle word wrap

  2. Publish the project: 

    $ dotnet publish mvc_runtime_example -f net10.0 /p:PublishProfile=DefaultContainer /p:ContainerBaseImage=registry.access.redhat.com/ubi9/dotnet-100-aspnet:latest
    Copy to Clipboard Toggle word wrap

  3. Run your image: 

    $ podman run --rm -p 8080:8080 mvc_runtime_example
    Copy to Clipboard Toggle word wrap

Verification

  1. View the application running in the container: 

    $ xdg-open http://127.0.0.1:8080
    Copy to Clipboard Toggle word wrap
