This document discusses using Docker images and containers in a Jenkins continuous integration/continuous delivery (CI/CD) pipeline. It describes configuring Jenkins to build Docker images from code repositories and deploy them to a Docker registry. It also covers using Docker Compose to define and run multi-container applications, and deploying containers to OpenShift, a Kubernetes-based Platform as a Service (PaaS). Future work mentioned includes improving scalability, using a Kubernetes cluster, adding MongoDB replication, and removing dependencies on host volumes.
