This document discusses using open source tools to support continuous delivery. It describes using GoCD for continuous delivery pipelines. GoCD is open source, created by ThoughtWorks, and focused specifically on continuous delivery. It also discusses using blue-green deployments with tools like Docker and Nginx for zero-downtime deployments. Finally, it provides references to additional open source tools that can be used for tasks like infrastructure as code, configuration management, load testing, and API testing in continuous delivery pipelines.
