This document discusses continuous delivery using Jenkins, Docker, and Spring Boot. It defines continuous delivery as getting changes safely and quickly into production. It describes using continuous integration with Jenkins to run automated tests on code commits. It advocates treating servers like "cattle, not pets" by using Docker containers with pre-built images from a registry for deployments. This allows applications to be deployed to different environments like staging and production more easily and consistently.

safely and quickly in a sustainable way

● Different environment in staging and production
● Different Java version for different applications
● Applications using the same ports
● Versioning
