CI/CD Overview

CI/CD (Continuous Integration and Continuous Deployment) automates the process of integrating code changes and deploying applications. It allows for faster and more reliable software delivery.

CI/CD Setup Status

As of now, CI/CD is not yet set up in the project. Below are the recommended next steps to establish a CI/CD pipeline.

Setting Up CI/CD

1. Choose a CI/CD Tool

Select a CI/CD tool that best fits the project needs. Popular options include:

• Jenkins
• GitHub Actions
• GitLab CI/CD
• CircleCI

2. Create Configuration Files

Depending on the tool chosen, create the necessary configuration files. Below are examples using GitHub Actions and Jenkins.

GitHub Actions

Create a new directory .github/workflows and add a YAML file, e.g., ci-cd.yml.

name: CI/CD Pipeline

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

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

      - name: Setup Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '14'

      - name: Install Dependencies
        run: npm install

      - name: Run Tests
        run: npm test

      - name: Build Project
        run: npm run build

      - name: Deploy
        run: echo "Deploying to production ..."

Jenkins

Create a Jenkinsfile in the root of the project.

pipeline {
    agent any

    stages {
        stage('Checkout') {
            steps {
                checkout scm
            }
        }
        stage('Install Dependencies') {
            steps {
                sh 'npm install'
            }
        }
        stage('Run Tests') {
            steps {
                sh 'npm test'
            }
        }
        stage('Build Project') {
            steps {
                sh 'npm run build'
            }
        }
        stage('Deploy') {
            steps {
                sh 'echo "Deploying to production ..."'
            }
        }
    }
}

3. Configure Environment Variables

Set environment variables specific to the daemons or processes you are using. These can be added in the settings of your CI/CD tool.

Example for GitHub Actions

In the repository settings, set the secret variables under “Secrets” such as DEPLOYMENT_TOKEN, which might be used in the deployment stage.

4. Configure Triggers

Define triggers that initiate the CI/CD pipeline. These triggers could be based on pushing code to branches or creating pull requests, as seen in the examples above.

5. Monitor and Adjust

Once deployed, monitor the CI/CD process and make adjustments as necessary. Use the logs provided by the CI/CD tool to troubleshoot and optimize pipeline performance.

Conclusion

Following these steps will integrate CI/CD into the project effectively. Further customizations can be made depending on the requirements of the project or the CI/CD tool being used.
