This module transitions you from basic Docker usage to engineering production-grade, pipeline-optimized containers. You will learn how to write highly efficient, multi-stage Dockerfiles that minimize image size and drastically reduce build times. We will explore how to leverage service containers for robust integration testing and dive deep into container security, including vulnerability scanning, non-root execution, and image signing. The module culminates in a hands-on guided lab where you will build, scan, and secure a multi-stage Docker pipeline from scratch.
