What is Jenkins Pipeline? Tutorial & Examples

Jenkins Pipeline automates CI/CD workflows by defining build, test, and deployment steps as code in a Jenkinsfile stored in version control. The guide covers pipeline fundamentals including declarative vs scripted syntax, key components (stages, steps, agents), and practical setup instructions. It explains how pipelines improve upon freestyle jobs through code-based configuration, parallel execution, and better reproducibility. The tutorial walks through creating a basic three-stage pipeline on Windows, configuring Git integration, and debugging common issues. Advanced features include multibranch pipelines for automatic per-branch job creation, environment variables, shared libraries, and post-build actions.
