Question 1

How do I enable HTTPS for ASP.NET Core in Docker?

Accepted Answer

Refer to the 'Hosting ASP.NET Core Images with Docker over HTTPS' sample in the repository, which guides configuring certificates and environment variables for secure container deployments.

Question 2

What's the difference between .NET SDK and runtime Docker images?

Accepted Answer

SDK images include build tools and are larger, ideal for development; runtime images are smaller with only execution dependencies, best for production. Use multi-stage builds to leverage both.

Question 3

How can I debug a .NET app running in a distroless container?

Accepted Answer

Use external tools like .NET Monitor or attach debuggers from outside the container, as distroless images lack shells. Consider switching to non-distroless variants for development phases.

Question 4

Is it better to use official .NET Docker images or build my own from scratch?

Accepted Answer

Official images save time with pre-configured best practices and security updates, but custom builds offer more control. For most teams, the official images are recommended due to Microsoft support.

Question 5

How often are .NET Docker images updated for security fixes?

Accepted Answer

Images are rebuilt within 12 hours for critical CVEs, monthly for lower-severity issues, and with every .NET release. Check the Image Update Policy in the README for specifics.

Question 6

How to change the default port for ASP.NET Core in Docker?

Accepted Answer

Configure Kestrel via environment variables or app settings; the README notes default port 8080 in .NET 8+, and use Docker port mapping (e.g., -p 8000:8080) to expose different host ports.
