FAQ
What is a Dockerfile?
A Dockerfile is a text file with instructions that Docker uses to build a container image — like a recipe for your app's environment.
What is a multi-stage build?
Multi-stage builds use multiple FROM instructions to separate build and runtime stages. The final image only contains what the app needs to run, making it much smaller and more secure.
Why use a non-root user in Docker?
Running containers as root is a security risk. If the container is compromised, an attacker would have root access. Use USER node (or similar) to run as a non-privileged user.
