Day 13 of DevOps leaning 🚀 :

- As I dive deeper into Jenkins, I've explored several intermediate concepts that are essential for building robust Continuous Integration/Continuous Deployment (CI/CD) pipelines. Here are some key takeaways:

👉 Jenkins Pipeline

Pipelines allow us to define our build processes in code.

Declarative pipelines offer a simpler syntax, while scripted pipelines provide more flexibility using Groovy.

👉 Pipeline as Code

With Jenkinsfile, we can version our pipeline alongside our application code, promoting collaboration and traceability.

👉 Jenkins Plugins

Plugins extend Jenkins’ capabilities, integrating seamlessly with tools like Git, Maven, and Slack. They can be managed easily from the dashboard.

👉 Distributed Builds

Jenkins supports a master-slave architecture, distributing build tasks across multiple agents to optimize resource usage and speed.

👉 Build Triggers

Triggers can start builds automatically on code changes, at scheduled intervals, or manually by users.

👉 Build Artifacts

Artifacts, such as binaries and zip files, are generated during builds and can be archived for future use.

👉 Environment Variables

These variables store configuration settings and sensitive information securely within Jenkins jobs.

👉 Error Handling

Implementing post-build actions helps manage build success or failure, while retry logic enhances reliability.

👉 Integration with Other Tools

Jenkins can be integrated with testing frameworks (e.g., JUnit, Selenium) and deployment tools (e.g., Docker, Kubernetes) to automate workflows effectively.

👉 Monitoring and Reporting

Jenkins provides detailed logs and reports for each build, allowing us to track progress and identify issues easily.
