Deploying Springboot app to PROD using Jenkins Pipeline projects

Firstly we have to set up a Jenkins

Creating a Job

• click on new item

• enter job name

• choose pipeline

• click on OK

• Our job is created.

Now we will install the required dependencies in our Master server

Required installations:

• Java 17

• maven

• git

yum install java-17-amazon-corretto.x86_64

using the above command java gets installed.

Maven setup:

first, we have to download maven

wget https://dlcdn.apache.org/maven/maven-3/3.9.1/binaries/apache-maven-3.9.1-bin.tar.gz

unzip and move maven to /opt -->

tar xvf apache-maven-3.9.1-bin.tar.gz -C /opt

to link with maven 3.9.1 -->

sudo ln -s /opt/apache-maven-3.9.1/ /opt/maven

To setup maven with java 17 we have to create write a script file 'maven.sh'

 sudo vim /etc/profile.d/maven.sh

export JAVA_HOME=/usr/lib/jvm/java-17-amazon-corretto export M2_HOME=/opt/maven export MAVEN_HOME=/opt/maven export PATH=${M2_HOME}/bin:${PATH}

we have to give executable permissions to the file and execute the script

sudo chmod +x /etc/profile.d/maven.sh 
source /etc/profile.d/maven.sh

Now you can verify the maven version using

mvn -v
Apache Maven 3.9.1 (2e178502fcdbffc201671fb2537d0cb4b4cc58f8)
Maven home: /opt/maven
Java version: 17.0.6, vendor: Amazon.com Inc., runtime: /usr/lib/jvm/java-17-amazon-corretto.x86_64
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.10.173-154.642.amzn2.x86_64", arch: "amd64", family: "unix"

Installing git

yum install git

Till now we have done set up in local/jenkins server

Now we are going to set up the required dependencies in the PROD server

Required dependencies:

• Java 17

• tomcat 10

below is the pipeline script

pipeline {
    agent any

    stages {
         stage('code') {
            steps {
                git branch: 'main', url: 'https://github.com/vishalsiripuram/newSpringWar.git'
            }
        }
           stage('build') {
            steps {
                sh '/opt/maven/bin/mvn clean package'
            }
           }
            stage('deploy') {
            steps {
                sh 'scp -o strictHostKeyChecking=no target/*.war root@172.31.92.53:/opt/apache-tomcat-10.1.7/webapps'
            }
        }
    }
}
