Deploy JBoss Wildfly Java EE app with Maven using Jenkins pipeline and Docker

HOWTO

GitHub projects

https://github.com/dveselka/java-ee-8/tree/main/java-ee8-minimal

Pipeline file https://github.com/dveselka/java-ee-8/blob/main/java-ee8-minimal/Jenkinsfile

Add jenkins user into docker group

sudo usermod -aG docker jenkins
sudo systemctl restart jenkins

Checkout app from GitHub

        stage('Checkout') {
          git url: 'https://github.com/dveselka/java-ee-8/', credentialsId: 'dave-devops', branch: 'main'
        }

Build application using Maven

        stage('Build') {
          
          dir('java-ee8-minimal'){
             withMaven(maven:'Maven'
             ) {
                sh 'pwd'
                sh 'env'
                sh 'mvn clean package'
            
                def pom = readMavenPom file:'pom.xml'
                print pom.version
                env.version = pom.version
             }
          }
        }

Build Docker image

https://www.jenkins.io/doc/book/pipeline/docker/

        stage("BuildDockerImage"){
          dir('java-ee8-minimal'){
            def customImage = docker.build("my-image:${env.BUILD_ID}")
          }
        }
