What problem does it solve?

This Skill provides best practices and techniques for containerizing .NET applications, ensuring efficient, secure, and minimal Docker images.

Core Features & Use Cases

• Multi-Stage Dockerfiles: Optimize image size and security by separating build and runtime environments.
• dotnet publish Container Images: Leverage built-in .NET 8+ functionality for direct container image creation.
• Rootless Containers: Enhance security by running containers as non-root users.
• Base Image Selection: Guidance on choosing the most appropriate .NET base images (e.g., chiseled, alpine).
• Container Optimization: Strategies for layer caching, .dockerignore, and memory management.
• Use Case: You need to deploy a .NET 8 ASP.NET Core API to a containerized environment. This Skill will guide you through creating an optimized, secure Dockerfile or using dotnet publish to generate the image, ensuring it runs as a non-root user.
