Jenkins

Step-by-step guide to create a Jenkins pipeline that deploys Helm charts to Kubernetes clusters with best practices.

Build Docker images, push to Nexus registry, and deploy with this complete Jenkins pipeline — a real-world CI/CD pattern used in production environments.

Configure Jenkins to automatically build on every GitHub push using webhooks, with proper authentication and branch filtering.

Add parameters to Jenkins pipelines for flexible, interactive builds — strings, booleans, choices, and file parameters with real examples.

Create shared libraries to standardise pipeline code across teams — vars, src, resources, and best practices.

Understand Jenkinsfile syntax and structure from scratch — declarative pipelines, stages, agents, and real examples you can copy.
