• Send CICD Pipeline Execution Status to Slack.

Tools and Technologies used are Java, Git, GitHub, Maven, SonarQube, Sonatype Nexus, Jenkins, Docker, DockerHub, Kubernetes and Amazon Web Services.

Project Execution

Git Checkout

  git branch: 'main', url: 'https://github.com/DevOpsCloudAutomation/JavaDockerApplication.git'

Build Project

Build Automation Tool Maven can be used to build this project as this project is developed using Java Programming Language.

  mvn clean package

Note:
Java and Maven should be installed as a prerequisite to Build Project Code.

Execute SonarQube Test

  mvn sonar:sonar

Upload Build Artifact to Sonatype Nexus

  mvn deploy

Build Docker Image

  docker build -t devopscloudautomation/webapplication:${buildNumber} .

Push Docker Image to Docker Hub Registry

  docker login -u devopscloudautomation -p ${Docker_Hub_Password}
  docker push devopscloudautomation/webapplication:${buildNumber}

Remove Docker Image Locally in Jenkins Server

  docker rmi -f devopscloudautomation/webapplication:${buildNumber}

Update Docker Image Tag in Kubernetes Manifest

  sed -i 's/Build_Tag/${Build_Number}/g' Deployment.yaml

Deploy Application to Kubernetes Cluster

  kubectl apply -f Deployment.yaml

  helm install helmwebapplication helmwebapplication -n production

Note
Application can be deployed to Kubernetes Cluster using Kubernetes Manifest Files as well as Helm Chart.
