Dockerfile
Definition
A Dockerfile is a text file containing sequential instructions for building a Docker container image. Each instruction (FROM, RUN, COPY, CMD) creates a new image layer.
Best practices include using specific base image tags, minimizing layers, leveraging multi-stage builds, and running processes as non-root users to produce secure, efficient images.

Every CISO is asking these three questions. We answer them with facts, not guesses, from repository to runtime.
