Chapter 1, Introducing Continuous Delivery, presents how companies traditionally deliver their software and explains the idea to improve it using the Continuous Delivery approach. This chapter also discusses the prerequisites for introducing the process and presents the system that will be built throughout the book.
Chapter 2, Introducing Docker, explains the idea of containerization and the fundamentals of the Docker tool. This chapter also shows how to use Docker commands, package an application as a Docker image, publish Docker container's ports, and use Docker volumes.
Chapter 3, Configuring Jenkins, presents how to install, configure, and scale Jenkins. This chapter also shows how to use Docker to simplify Jenkins configuration and to enable dynamic slave provisioning.
Chapter 4, Continuous Integration Pipeline, explains the idea of pipelining and introduces the Jenkinsfile syntax. This chapters also shows how to configure a complete Continuous Integration pipeline.
Chapter 5, Automated Acceptance Testing, presents the idea and implementation of acceptance testing. This chapters also explains the meaning of artifact repositories, the orchestration using Docker Compose, and frameworks for writing BDD-oriented acceptance tests.
Chapter 6, Configuration Management with Ansible, introduces the concept of configuration management and its implementation using Ansible. The chapter also shows how to use Ansible together with Docker and Docker Compose.
Chapter 7, Continuous Delivery Pipeline, combines all the knowledge from the previous chapters in order to build the complete Continuous Delivery process. The chapter also discusses various environments and the aspects of nonfunctional testing.
Chapter 8, Clustering with Docker Swarm, explains the concept of server clustering and the implementation using Docker Swarm. The chapter also compares alternative clustering tools (Kubernetes and Apache Mesos) and explains how to use clustering for dynamic Jenkins agents.
Chapter 9, Advanced Continuous Delivery, presents a mixture of different aspects related to the Continuous Delivery process: database management, parallel pipeline steps, rollback strategies, legacy systems, and zero-downtime deployments. The chapter also includes best practices for the Continuous Delivery process.
