Dockerfile Best-Practice Generator

Veelgestelde vragen

Quick answers.

›Why use multi-stage builds?

Multi-stage builds separate the compilation environment from the final runtime environment. This reduces the attack surface and significantly shrinks the final image size by excluding compilers and header files.

›Is my configuration sent to a server?

No. The logic for generating the `Dockerfile` and `.dockerignore` content runs entirely in your browser using local templates.

›Why does the generator add a non-root user?

Running containers as root is a security risk. Best practice dictates creating a dedicated user with limited permissions to run the application process inside the container.

›What is the purpose of the .dockerignore file?

It prevents local files like `node_modules`, `.git`, and secret files from being sent to the Docker daemon. This speeds up the build process and prevents sensitive data from accidentally ending up in an image layer.
