benhall / express-demo

This document outlines the CI/CD deployment process for the benhall/express-demo project. As of now, it appears that CI/CD has not yet been set up for this project. Below are recommended steps to implement CI/CD effectively.

Next Steps for Setting Up CI/CD

  1. Select a CI/CD Tool: Choose an appropriate CI/CD tool that aligns with the project requirements. Options include:

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

  2. Create Configuration Files: Depending on the CI/CD tool chosen, create the necessary configuration files to define the build, test, and deployment processes.

  3. Integrate Docker: Since the project utilizes Docker, ensure that your CI/CD pipeline integrates Docker commands to build the application image using the Dockerfile and manage deployments.

  4. Define Pipeline Stages: Create stages in your pipeline for the build process, testing, and deployment to environments (if applicable).

Example CI/CD Configuration

The following is a hypothetical example demonstrating how to set up a CI/CD pipeline using GitHub Actions based on the existing project structure.

Step 1: Create a GitHub Actions Workflow

In the root directory of your project, create a .github/workflows/ci-cd.yml file.

name: CI/CD Pipeline

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

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

      - name: Set up Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '20.11.0'
  
      - name: Install Dependencies
        run: |
          npm ci

      - name: Build Application
        run: |
          npm run build

      - name: Build Docker Image
        run: |
          docker build -t benhall/express-demo .

      - name: Push Docker Image
        run: |
          echo "${{ secrets.DOCKER_PASSWORD }}" | docker login -u "${{ secrets.DOCKER_USERNAME }}" --password-stdin
          docker tag benhall/express-demo:latest your-docker-repo/benhall/express-demo:latest
          docker push your-docker-repo/benhall/express-demo:latest

      - name: Deploy to Production
        run: |
          # Command to deploy your image (this can vary based on the deployment strategy)
          ssh user@your-server "docker pull your-docker-repo/benhall/express-demo:latest && docker-compose up -d"

Step 2: Configure Docker

The provided Dockerfile is essential for building the Docker image, as it sets up the environment and exposes the necessary ports.

Here’s an excerpt of the Dockerfile showcasing the port exposure:

FROM node:${NODE}

# Create app directory
WORKDIR /usr/src/app

# Expose the port the app runs on
EXPOSE 3000

CMD [ "./bin/www" ]

When utilizing Docker, ensure your docker-compose.yml is configured to route traffic correctly:

version: "3.9"
services:
  web:
    build: .
    ports:
      - "3000:3000"

Conclusion

Setting up a CI/CD process for benhall/express-demo requires the selection of a suitable tool, creation of configuration files, integration of Docker builds, and deployment processes. By following the outlined steps and examples, effective CI/CD practices can be established for the project.
