What problem does it solve?

Containerizing .NET 10 applications can produce large, insecure, and slow-to-build images when best practices are not followed; this Skill provides clear patterns to produce lean, secure, and cache-friendly containers and Compose setups for local development and CI.

Core Features & Use Cases

• Multi-stage builds to separate build and runtime stages and minimize final image size.
• Layer caching pattern: copy project files and restore before copying full source to speed incremental builds.
• Non-root runtime and security guidance to avoid running containers as root in production.
• Health checks and lightweight /health endpoints to enable orchestrator and Docker health monitoring.
• Docker Compose patterns for local development including environment-driven connection strings and service dependency health checks.
• Use case: Containerize an ASP.NET Core Web API using a solution-based restore approach, publish to /app/publish, run with the aspnet runtime as a non-root user, expose a health endpoint, and orchestrate with Compose for local dev.

Quick Start

Create a multi-stage Dockerfile for your .NET 10 Web API that restores via project-file-first, publishes to /app/publish, uses the aspnet runtime with USER app, and exposes a /health endpoint.
