Learn JENKINS-PIPELINE with Real Code Examples

Jenkins master schedules and monitors pipelines

Agents (nodes) execute pipeline steps

Pipeline script (Jenkinsfile) stored in SCM

Stages execute sequentially or in parallel

Post actions handle notifications, cleanup, or archiving

Jenkinsfile -> Parse -> Stages -> Steps -> Agents execute -> Post actions -> Notifications/logs

Supports parallel and sequential execution

Pipeline state managed by Jenkins master

Artifacts and build outputs tracked

Integrates with SCM and external tools for end-to-end automation

Single pipeline per repository

Multi-branch pipeline for feature branches

Parallel stages for faster execution

Parameterized pipelines for dynamic builds

Integration with containerized and cloud environments

Microservices CI/CD pipelines

Docker/Kubernetes deployment pipelines

Automated testing pipelines for QA

Multi-branch feature/release pipelines

End-to-end enterprise software delivery workflows

Pipeline as code

Automation of build, test, deploy

Reproducibility across environments

Extensible via plugins
