Installation of Jenkins

The following steps outline the process of installing and configuring Jenkins for continuous integration.

Step 1: Prepare the Jenkins Environment​

  1. Ensure that you have a dedicated machine or a local environment to deploy Jenkins.
  2. Create a separate directory for your continuous integration setup.
.
├── README.md
├── docker-compose.yaml
├── infrastructurePipeline
│   └── Jenkinsfile
└── installgcloud.bash
  1. Navigate to the continuous integration folder.
cd ContinousIntegration

Step 2: Launch Jenkins Docker Container​

Create a docker-compose.yaml file with the following content to configure and launch the Jenkins Docker container:

version: '3'
services:
  jenkins:
    image: jenkins/jenkins:2.401.1-lts-jdk11
    container_name: jenkins
    user: root
    ports:
      - 8080:8080
      - 50000:50000
    volumes:
      - jenkins_home:/var/jenkins_home
    restart: always
volumes:
  jenkins_home:

Start the Jenkins container by running the following command:

docker-compose up -d

Step 3: Install Required Plugins​

  1. Access the Jenkins web interface by opening a browser and visiting http://localhost:8080.
  2. Install the following plugins through the Jenkins Plugin Manager:
    • Pipeline
    • Terraform
    • Docker
    • Kubernetes (Kube)
    • Google Cloud CLI (gcloud)

Step 4: Configure Jenkins Credentials​

  1. Add your service account credentials as a secret file in Jenkins. This will allow Jenkins to access the necessary resources for deployment.
  2. Follow the Jenkins documentation to add the credentials as a secret file.

Step 5: Create and Configure the Pipeline​

  1. Create a new pipeline in Jenkins.
  2. Copy the contents of the Jenkinsfile located in the infrastructurePipeline folder and paste it into the pipeline configuration.

Step 6: Configure Triggers​

Configure the triggers for your pipeline according to your requirements. For example, you can trigger the pipeline on code commits or on a schedule.

Step 7: Build the Pipeline​

Save your pipeline configuration and build the pipeline. Jenkins will now execute the defined steps in the pipeline, deploying your infrastructure as specified in the Jenkinsfile.

NOTE

This is a general overview of the installation and configuration process. Further customization and adjustments may be required based on your specific requirements.
