Jenkins CI CD
===============

1) Build & Deployment process

2) Challenges with Manual build & deployment

3) Jenkins Introduction

4) Jenkins Setup

5) Jenkins CI CD Pipeline

6) Git + Maven + Docker + Jenkins


=============================
What is Build & Deployment
=============================

1) Take latest source code from git hub repo

2) Compile Source Code

3) Execute Unit Test cases

4) Package our application (jar/war)

5) Build Docker image

6) Create Docker container

========================================
Challenges in Manual build & deployment
========================================

1) Every day we need to deploy latest code 

2) Deploy code in multiple environments

		Ex: DEV, SIT, UAT and PROD

3) Takes lot of time

4) Repeated Work

5) Error Prone

==================
What is Jenkins ?
==================

1) Jenkins is free & open source software

2) Jenkins developed using Java language

3) Jenkins is used to automate Build & Deployment process

4) Using Jenkins we can implement CI CD


=> CI CD means continuous integration and continous deployment.

===============
Jenkins Setup
===============

======================
Jenkins Pipeline
======================

=> Jenkins pipeline contains set of steps to automate project build and deployment process.

=> We can create jenkins pipeline in 2 ways

		1) Declarative pipeline

		2) Scripted Pipeline (groovy)

=====================================
Jenkins Declarative Pipeline Syntax
=====================================		

pipeline {
	
	agent any 

	stages {
		stage('Hello'){
			steps{
				// logic
			}
		}
	}
}
