2.2 Pipeline CI/CD — GitHub, Maven, Jenkins, Artifactory, SonarQube, Docker, Ansible, Tomcat

This is the continuation to the Previous Post 2.1 Pipeline CI/CD — GitHub, Maven, Jenkins, Artifactory, SonarQube, Docker, Ansible, Tomcat

• Breaking the Code:

Link to the Jenkins File — Click

Jenkins Pipeline Style: Declarative Jenkins Pipeline

Fig1.1

In the above Screenshot Fig.1.1

• Defined the maven and Artifactory methods globally in Jenkins File
• Defined the method DockerTag() globally to get the latest commit ID
• Included the options to have the timestamps and log rotation of the builds.
• Set the tools name of Java and Maven location as mentioned in the Jenkins — Global Tool Configuration ( Refer Screenshot Fig1.2) below.

Fig1.2

Set the Environment of SonarQube scanner tool name as mentioned in the Jenkins — Global Tool Configuration ( Refer Screenshot Fig1.2) above.

Fig1.3

• In the Screenshot above Fig1.3 explains the Artifactory, SonarQube Analysis, SonarQube Quality gate Stage.

Note: “ Quality Gate” stage is written in the Jenkins File to make the Jenkins build fail if the Sonar Quality Gate metrics is not met.

Fig1.4

• In the Screenshot above Fig1.4, the docker image is build and pushed to the Docker Hub.

Fig1.5

• Running the Docker Container of tomcat to port 8050

Note: Dockerfile is found here

• In the above Screenshot Fig1.5, changed the RUN command to startup the tomcat server with the Port 8050 ( Default port is 8080)

Fig1.6

• The above screenshot explains about the triggering of the Ansible Playbook. Please find the screenshot of the Ansible Playbook below. Refer Fig.1.6

Fig1.7

• In the Playbook, vars is written to get the output of the latest commit ID of the Git referencing from the environment variable ‘DOCKER_TAG’ [Refer Fig1.1] in the Jenkinsfile
• Defined the tasks to delete the previous / old containers and the images.
• ignore_errors is mentioned in the tasks for error handling.
• “creating docker image” task is to run the container with the tag of the latest git commit.

Conclusion:

We have integrated the Jenkins with the Ansible and made the playbook to run in the target machines. In our lab setup, the targets are the tomcat server ( created from the Docker) which is mentioned in the inventory file.

I hope this guide helped you! Enjoy Learning and have fun!!! 😊😊
