Section 4 – Infrastructure and automation

Chapter 17, Migrating to Docker, migrates our application to run inside Docker containers. Initially, you'll learn about control groups and namespaces and how they enable containers to work. Then you'll write your own Dockerfiles and build and optimize your Docker images.

Chapter 18, Robust Infrastructure with Kubernetes, deploys our application into a cluster using Kubernetes, a cluster management tool that combines discovery services, global configuration stores, schedulers, and load balancers. This ensures that our application is highly-available, reliable, scalable, and performant.
