Prerequisites

  1. Azure vm with tomcat installation
  2. Jenkins server

Part-01 : Adding steps for Integration

Steps to create Jenkin job

  1. Login to Jenkins console
  2. Create Jenkins job, Fill the following details,
    • Source Code Management:
      • Repository: https://github.com/Ancordss/java-maven.git
      • Branches to build : */master
    • Build:
      • Root POM:pom.xml
      • Goals and options : clean install package

Part-02: Adding Deployment Steps

in this port we are going to install ‘deploy to container’ plugin. this is need to deploy on tomcat server which we are using.

  • Install maven plugin without restart
    • Manage Jenkins > Jenkins Plugins > available > deploy to container

To deploy our build artifacts on tomcat server our Jenkins server need access. For this we should setup credentials. This option is available in Jenkins home page

  • setup credentials
    • credentials > jenkins > Global credentials > add credentials
      • Username : deployer
      • Password : XXXXXXX
      • id : Tomcat_user
      • Description: Tomcat user to deploy on tomcat server

Modify the same job which created in part-01 and add deployment steps.

  • Post Steps
    • Deploy war/ear to container
      • WAR/EAR files : **/*.war
      • Containers : Tomcat 8.x
        • Credentials: Tomcat_user (which created in above step)
        • Tomcat URL : http://<PUBLIC_IP>:<PORT_NO>

Save and run the job now.

Port-03 : Continuous Integration & Continuous Deployment (CI/CD)

Now job is running fine but to make this as Continuous Integration and Continuous Deployment Tod do that go back and modify job as below.

  • Build Triggers
    • Poll SCM
      • schedule */2 * * * *

Save the job and modify the code in GitHub. Then you could see your job get trigger a build without any manual intervention.
