What are the best practices for writing a Dockerfile?

Some best practices include using a minimal base image, combining commands to reduce layers, and specifying a non-root user.

Why is it important to use a minimal base image?

Using a minimal base image reduces the attack surface, speeds up builds, and decreases the final image size.

How can I optimize the build process in my Dockerfile?

You can optimize the build process by leveraging Docker's caching mechanism, ordering commands efficiently, and cleaning up unnecessary files.

What should I avoid when writing a Dockerfile?

Avoid using unnecessary packages, hardcoding values, and running multiple commands in a single layer without cleanup.
