DevOps Project

Maven Project Jenkins SonarQube Nexus

• In this project, we will be playing with Github, Jenkins,Sonarqube and Nexus.
• We will create Jenkins, Sonarqube and Nexus from Docker Container.
• Since we will require docker inside Jenkins. But the official jenkins image do not include docker inside the image. So we will create our own new Jenkins image.
• The jenkins image used in this project can be pull from dockerhub. Visit the link.

Github:

• In this project, Git is used as VCS(Version Control System).
• Github is used to store Source Code.

Jenkins:

• Jenkins is used for CI/CD(Continuous Integration/Continuous Deployment).
• We will be using Declarative pipeline for this job.

Declarative Pipeline:

• This pipeline will contain multiple stages where task will be describe.
• Jenkins automatically fetched the Github Repo, so we do not need to include that in any stage.
• Multiple stages included in this job are:

  • Stage 1:

    • Since this is maven based application, we will run the mvn test command.

  • Stage 2:

    • Skip the Unit Test.

  • Stage 3:

    • Clean the prebuild package and install create a new package.

  • Stage 4:

    • Create a Project in Sonarqube. Remember it requires a Sonarqube Credentials.

  • Stage 5:

    • Get quality status report back from Sonarqube.
    • For this, we must create jenkins webhook in sonarqube.

  • Stage 6:

    • Upload the artifact to the Nexus Repository.
    • It reqiures Nexus Credentials to upload the artifact.

  • Stage 7:

    • It builds a docker image of the application with the Job_Name and Build_ID.
    • Remember, Docker must be installed inside Jenkins.

  • Stage 8:

    • It tagged the image with registry.

  • Stage 9:

    • It pushes the image to the Nexus Private Registry.
    • It reqires Nexus credentials for that.

  • Stage 10:

    • It removes old image to clean the space from the jenkins container.

  • Stage 11:

    • Deploy the application from the docker image.

Sonarqube:

• Sonarqube is used for Code Analysis.

Nexus:

• Nexus is used for private repository.
