1. Jenkins CI/CD Pipeline for Flask Application

Objective

Set up a Jenkins pipeline to automate the testing and deployment of a simple Python web application.

Requirements

1. Setup:

• Install Jenkins on a virtual machine or use a cloud-based Jenkins service.
• Configure Jenkins with Python and any necessary libraries.

2. Source Code:

• Fork the provided Python web application repository on GitHub.
• Clone the forked repository into your Jenkins server.

3. Jenkins Pipeline:

• Create a Jenkinsfile in the root of your Python application repository.
• Define a pipeline with the following stages:
  • Build: Install dependencies using pip.
  • Test: Run unit tests using a testing framework like pytest.
  • Deploy: If tests pass, deploy the application to a staging environment.

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                script {
                    // Install dependencies using pip
                    sh 'pip install -r requirements.txt'
                }
            }
        }

        stage('Test') {
            steps {
                script {
                    // Run unit tests using pytest
                    sh 'pytest'
                }
            }
        }

        stage('Deploy') {
            when {
                expression { currentBuild.resultIsBetterOrEqualTo('SUCCESS') }
            }
            steps {
                script {
                    // Deploy to staging environment (replace with your deployment script)
                    sh './deploy-to-staging.sh'
                }
            }
        }
    }

    post {
        always {
            // Clean up or perform any post-build actions here
        }
    }
}

4. Triggers:

• Configure the pipeline to trigger a new build whenever changes are pushed to the main branch of the repository.

5. Notifications:

• Set up a notification system to alert via email when the build process fails or succeeds.

6. Documentation:

• Document the pipeline process and any prerequisites needed for the setup in a README.md file in the repository.

7. Submission:

• The URL to the GitHub repository with the Jenkinsfile and updated README.md.
• Include screenshots of the Jenkins pipeline showing the build, test, and deployment stages.

2. GitHub Actions CI/CD Pipeline for Flask App

Objective

Implement a CI/CD workflow using GitHub Actions for a Python application.

Requirements

1. Setup:

• Use a provided Python application repository on GitHub.
• Ensure the repository has a main branch and a staging branch.

2. GitHub Actions Workflow:

• Create a .github/workflows directory in your repository.
• Inside the directory, create a YAML file to define the workflow.

name: Python CI/CD

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout repository
      uses: actions/checkout@v2

    - name: Set up Python
      uses: actions/setup-python@v3
      with:
        python-version: 3.8

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install -r requirements.txt

    - name: Run tests
      run: pytest

  deploy-staging:
    runs-on: ubuntu-latest
    needs: build
    if: github.event_name == 'push' && git

3. Workflow Steps:

• Define a workflow that performs the following jobs:
  • Install Dependencies: Install all necessary dependencies for the Python application using pip.
  • Run Tests: Execute the test suite using a framework like pytest.
  • Build: If tests pass, prepare the application for deployment.
  • Deploy to Staging: Deploy the application to a staging environment when changes are pushed to the staging branch.
  • Deploy to Production: Deploy the application to production when a release is tagged.

4. Environment Secrets:

• Use GitHub Secrets to store sensitive information required for deployments (e.g., deployment keys, API tokens).

5. Documentation:

• Update the README.md file with instructions on how the GitHub Actions workflow works and how to configure the necessary secrets.

6. Submission:

• The URL to the GitHub repository with the workflow file and updated README.md.
• Include screenshots of the GitHub Actions workflow runs showing successful execution of all steps.
