Containerize Aspnetcore

Creates a production-ready Dockerfile and .dockerignore for ASP.NET Core projects with proper multi-stage builds, security practices, and Linux distribution support. Handles the tedious bits like setting non-root users, configuring ASPNETCORE_URLS, managing NuGet feeds, and installing system dependencies. Good for when you need more than a basic containerization setup but don't want to research Microsoft's latest base image tags or remember all the Docker best practices. The extensive configuration options cover most real-world scenarios, from custom health checks to volume mounts, though you'll probably only need the first few settings for typical projects.

ASP.NET Core Docker Containerization Prompt

Containerization Request

Containerize the ASP.NET Core (.NET) project specified in the settings below, focusing exclusively on changes required for the application to run in a Linux Docker container. Containerization should consider all settings specified here.

Abide by best practices for containerizing .NET Core applications, ensuring that the container is optimized for performance, security, and maintainability.

Containerization Settings

This section of the prompt contains the specific settings and configurations required for containerizing the ASP.NET Core application. Prior to running this prompt, ensure that the settings are filled out with the necessary information. Note that in many cases, only the first few settings are required. Later settings can be left as defaults if they do not apply to the project being containerized.

Any settings that are not specified will be set to default values. The default values are provided in [square brackets].
