Pipeline Overview​

Build Process​

GitHub Actions Workflow​

name: CI/CD Pipeline

on:
  push:
    branches: [ main, develop ]
  pull_request:
    branches: [ main, develop ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Setup Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '18'
      
      - name: Install Dependencies
        run: npm ci
      
      - name: Lint Check
        run: npm run lint
      
      - name: Run Tests
        run: npm run test
      
      - name: Build
        run: npm run build

Deployment Strategy​

Environment Configuration​

Development​

environment:
  name: development
  url: https://dev.oanfinance.com
  
variables:
  NODE_ENV: development
  API_URL: https://api.dev.oanfinance.com
  LOG_LEVEL: debug

Staging​

environment:
  name: staging
  url: https://staging.oanfinance.com
  
variables:
  NODE_ENV: staging
  API_URL: https://api.staging.oanfinance.com
  LOG_LEVEL: info

Production​

environment:
  name: production
  url: https://oanfinance.com
  
variables:
  NODE_ENV: production
  API_URL: https://api.oanfinance.com
  LOG_LEVEL: error

Kubernetes Deployment​

Deployment Configuration​

apiVersion: apps/v1
kind: Deployment
metadata:
  name: oan-frontend
spec:
  replicas: 3
  selector:
    matchLabels:
      app: oan-frontend
  template:
    metadata:
      labels:
        app: oan-frontend
    spec:
      containers:
      - name: oan-frontend
        image: oan-frontend:latest
        ports:
        - containerPort: 80

Monitoring & Alerts​

Rollback Process​

Rollback Steps​

  1. Identify issue in new deployment
  2. Initiate rollback procedure
  3. Verify previous version deployment
  4. Update DNS/routing
  5. Verify system stability
  6. Investigate root cause
