Chapter summary
In this chapter, you learned that CI/CD automates the building, testing, and deployment of software and infrastructure. CI deals with automating the early steps of building and testing code, and then publishing it to repositories. CD takes the built and tested artefact and automates the process of deploying it to live environments. GitOps builds on this by adding version control, pull requests, and approvals that trigger the CD process. GitOps is particularly powerful in Kubernetes environments where everything is declaratively described in YAML configuration files that are used to configure the environment. Popular GitOps tools include Argo, Flux, and Jenkins X.
