🔧 Configuration

Nginx Configuration

The nginx.conf file is pre-configured with:

• Gzip compression for faster loading
• Security headers (X-Frame-Options, X-Content-Type-Options, etc.)
• Static file caching for optimal performance
• Health checks for monitoring

Adding New Documentation

1. Add your .md file to the docs/ directory
2. Update public/js/viewer.js - Add entry to DOC_MAP:

   const DOC_MAP = {
       'YOUR_DOC': '/docs/YOUR_DOC.md',
       // ... existing entries
   };
   

3. Update public/index.html - Add link to homepage (optional)
4. Update public/viewer.html - Add to sidebar navigation (optional)
5. Rebuild Docker image if using Docker

    --secondary-color: #424242;   /* Secondary color */
    --success-color: #4caf50;     /* Success messages */
    --warning-color: #ff9800;     /* Warnings */

🌐 Deployment

Production Deployment

1. Build the image:

   docker build -t goa-gel-docs:v1.0.0 .
   

2. Tag for registry:

   docker tag goa-gel-docs:v1.0.0 your-registry/goa-gel-docs:v1.0.0
   

3. Push to registry:

   docker push your-registry/goa-gel-docs:v1.0.0
   

4. Deploy to server:

   docker run -d \
     -p 80:80 \
     --name goa-gel-docs \
     --restart always \
     your-registry/goa-gel-docs:v1.0.0
   

Reverse Proxy (Nginx/Apache)

If using a reverse proxy, configure it to forward to port 8080:

Nginx example:

server {
    listen 80;
    server_name docs.goa-gel.gov.in;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Kubernetes Deployment

Create a deployment YAML:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: goa-gel-docs
spec:
  replicas: 2
  selector:
    matchLabels:
      app: goa-gel-docs
  template:
    metadata:
      labels:
        app: goa-gel-docs
    spec:
      containers:
      - name: goa-gel-docs
        image: your-registry/goa-gel-docs:v1.0.0
        ports:
        - containerPort: 80
        resources:
          limits:
            memory: "256Mi"
            cpu: "500m"
---
apiVersion: v1
kind: Service
metadata:
  name: goa-gel-docs
spec:
  selector:
    app: goa-gel-docs
  ports:
  - port: 80
    targetPort: 80
  type: LoadBalancer
