docker

To create a multi-stage Dockerfile for .NET 10, separate the SDK build environment from the lightweight runtime environment. This approach minimizes final image size by compiling source code in an initial stage and copying only published outputs to the runtime stage.

Configuring a .NET Docker container to run as a non-root user involves setting the built-in non-root user in your Dockerfile runtime stage. This security configuration ensures the application process executes without administrative privileges inside the container.

Optimizing Docker layer caching for .NET applications requires copying project files and restoring dependencies before copying the full source code. This Dockerfile pattern prevents unnecessary package restore executions when only application source files change.

Adding a HEALTHCHECK to a .NET Docker Compose deployment requires wiring a container health check to a lightweight application endpoint. This configuration enables orchestration tools to monitor application readiness and manage dependencies based on health status.

When a .NET Docker build context includes unnecessary files, optimizing the .dockerignore file prevents build-context bloat. This minimization step stops local artifacts and source directories from invalidating Docker layer caches during the build process.

Docker Compose works with .NET 10 local orchestration workflows by defining multi-container environments. It uses health-based dependencies to ensure your .NET application starts only after required services pass their configured health checks.
