DevOps

Day 14 of DevOps Learning 🚀 :
Today I covered some of the advance topics of Jenkins
- Pipeline as Code: Use Declarative and Scripted Pipelines to define CI/CD workflows in the Jenkinsfile for version control and modularity.
- Shared Libraries: Reuse common functions across pipelines by creating Global or Local Shared Libraries.
- Pipeline Triggers: Automate builds with cron, webhooks, or SCM polling to respond to code changes.
- Parallel Execution: Run tasks concurrently using parallel steps in the pipeline, improving build/test efficiency.
- Advanced Credentials Management: Secure sensitive data with Jenkins Credentials and use credentials-binding to pass them securely.
- Jenkins Agents: Use master-slave architecture for distributed builds and dynamic agents (Docker, Kubernetes) to scale as needed.
- Pipeline Features: Leverage advanced options like timeouts, parameters, and tool configurations in pipelines.
- Blue Ocean UI: Visualize complex pipelines with a modern, user-friendly interface in Blue Ocean.
- Notifications: Automate notifications for build statuses using email or Slack.
- Docker/Kubernetes Integration: Use Jenkins with Docker or Kubernetes for containerized builds and scalable environments.
- Multibranch Pipelines: Automate jobs for every branch or PR in a Git repo using multibranch pipelines.
- Role-Based Access Control (RBAC): Restrict access with roles to secure Jenkins operations.
- Artifact Management & Caching: Use Nexus, Artifactory, and caching techniques to optimize builds and manage artifacts.
- Complex Workflows: Include manual approvals, multi-environment builds, and complex CI/CD stages using Jenkinsfile.
- Monitoring: Integrate with Prometheus, Grafana, or other tools for performance monitoring and metrics tracking.
