This document discusses using continuous integration with Docker and Ansible. It describes building and deploying microservices across multiple technologies using Docker containers managed by Ansible playbooks. The process involves cloning repositories, building Docker images, testing, pushing images to a private Docker registry, and deploying containers to environments with Ansible. Benefits include easily managing container environments, portability across machines, and isolated workspaces for each service. Challenges addressed are timeouts, freezes, and long build times.
