The document outlines the OpenShift Container Platform CI/CD processes including build and deployment strategies using Jenkins and source-to-image (S2I) methods. It describes the integration of various components such as Git repositories, application binaries, and Docker images along with triggers for continuous integration and continuous delivery. Additionally, it emphasizes the hybrid Jenkins infrastructure capabilities with OpenShift for scaling and managing CI/CD pipelines effectively.

● Webhook triggers: build the app image whenever the code changes
● Image trigger: build the app image whenever the base language or app runtime changes
● Build hooks: test the app image before pushing it to an image registry
DEPLOYMENTS
● Deployment triggers: redeploy app containers whenever configuration changes or the
image changes in the OpenShift integrated registry or upstream registries

OPENSHIFT PIPELINES
● OpenShift Pipelines allow defining a
CI/CD workflow via a Jenkins pipeline
which can be started, monitored, and
managed similar to other builds
● Dynamic provisioning of Jenkins slaves
● Auto-provisioning of Jenkins server
● OpenShift Pipeline strategies
○ Embedded Jenkinsfile
○ Jenkinsfile from a Git repository
