Automated Deployment Pipeline with Jenkins and Docker

Graduation Project Of DEPI DevOps Track

Project Overview

This project automates the setup and deployment process using the following tools:

  1. Terraform to create an EC2 instance on AWS.
  2. Ansible to install Docker and Jenkins on the EC2 instance.
  3. Jenkins for Continuous Integration/Continuous Deployment (CI/CD) to automate the Dockerization and deployment of a Flask Python application.

Creating EC2 Instance on AWS using Terraform

  1. Configure Terraform:

  • Create VPC and define the networking structure (subnets, route tables, security groups, etc..).
  • Outputs:
    • Capture the public IP of Ec2.
  • The EC2 instance IP will be in the inventory file for Ansible.

  1. Installing Docker and Jenkins on EC2 using Ansible

Ansible will handle the installation of Docker and Jenkins on the EC2 instance.

  • Create Ansible Playbook:
    • Create playbook to install jenkins and docker on Ec2 Instance.
  • Run Ansible Playbook:
    • Run the playbook
ansible-playbook -i inventory.yml playbook.yml

  1. Dockerizing Flask App

  • Create Dockerfile:
    • Inside your Flask app directory, create Dockerfile:
  • Build and Run Docker Container:
    • Build the Docker image
docker build -t flask_app .
  • Run the container:
docker run -p 5000:5000 flask_app
  • push it to DockerHub
    • push your image to Docker Hub
      • create a new repository in DockerHub.
      • push the image by docker push.

  1. Automating CI/CD with Jenkins

  • Create Jenkins Pipeline:
    • In Jenkins, configure a new pipeline job for the Flask app.
    • Add the following Jenkinsfile in your project repository.
  • Set Up Jenkins Webhook:
    • Go to your GitHub repository settings.
    • set up a webhook to trigger the Jenkins pipeline when code is pushed or updated.
  • Run the Pipeline:
    • Jenkins will automatically
      • detect changes in the repository
      • build the Docker image
      • test and deploy the Flask application.

    Conclusion

    This setup automates the creation of an EC2 instance, the installation of Docker and Jenkins using Ansible, and the
    Dockerization and deployment of a Flask app. Jenkins ensures that any updates to the repository trigger the CI/CD pipeline, keeping the application deployment automated and up-to-date.
