Frequently Asked Questions (FAQ)

What is multi-stage build is and why should you use it?

Multi-stage build helps reduce image size by separating build-time dependencies from runtime dependencies. The result is smaller, more secure production images.

Why should we use non-root users in Docker?

Non-root user improves security by limiting container permissions. This is a security best practice that helps reduce attack surface and prevent privilege escalation attacks.

How to optimize Docker image size?

Use multi-stage builds, choose minimal base images (Alpine), remove unnecessary dependencies, and optimize layer ordering to leverage Docker cache effectively.
