3.2 Pipeline CI/CD — GitHub, Maven, Jenkins, Artifactory, SonarQube, Docker, Tomcat, Kubernetes ( Pods and Services)

This is the continuation to the Previous Post 3.1 Pipeline CI/CD — GitHub, Maven, Jenkins, Artifactory, SonarQube, Docker, Tomcat, Kubernetes ( Pods and Services)

• 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 8090

Note: Dockerfile is found here

• In the above Screenshot Fig1.5, changed the RUN command to startup the tomcat server with the Port 8090 ( Default port is 8080)

Fig1.6

• In the above Screenshot Fig1.6 defined the two actions

> Shell script named “replace.sh” ( Refer Fig1.7) to append the DOCKER_TAG value to the pod.yml and create the new file called changed-pod.yml

> We are connecting to the Kubernetes Master through the SSH Agent Authentication.

> We are running the changed-pod.yml , services.yml in the Kubernetes Master

> Using the Try & Catch Block to catch the exceptions if any, to avoid the break of the Pipeline stages.

Fig1.8

Conclusion:

We have integrated the Jenkins with the Kubernetes Cluster using the SSH Agent and made the Kubernetes master to spin the Pods and Services as a part of the container orchestration.

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