Branching strategy

• Refer Here for git flow branching strategy
• Other two branching stratgies
  • trunk based development (old)
  • git lab branching strategy

Pipeline

• Overview
  
• Steps
  • Jenkins Server with 3 nodes
    • 1 node for building the code with label build
    • ensure sonar qube is setup
    • 1 nodes add as agents with label systemtest
    • 1 nodes add as agents with label perftest
• Experiment
  • Write a pipeline where you build spring petclinic, perform sonar qube and then create two stages
    • ST: here run on agent with label systemtest and step is sleep 5m
    • PT: here run on agent with label perftest and step is sleep 7m
  • Ensure both stages ST and PT execute in parallel

pipeline {
    agent none
    stages {
        stage('SCM') {
            agent { label 'build' }
            steps {
                git url: '',
                    branch ''
            }
        }
        stage('Build') {
            agent { label 'build' }
            steps {
                sh 'mvn clean package'
            }
        }
        stage('Deploy') {
            parallel {
                stage('ST') {
                    agent { label 'ST' }
                    steps {
                        sh 'sleep 5m'
                        // Add commands to run unit tests here
                        // terraform
                    }
                }
                stage('PT') {
                    agent { label 'PT' }
                    steps {
                        sh 'sleep 7m'
                        // Add commands to run integration tests here
                        // terraform
                    }
                }
            }
        }

    }
