+# Server-Sent Events (SSE) Infrastructure
+
+This document describes the SSE implementation for real-time server-to-client communication in the Adopt-a-Street backend.
+
+## Overview
+
+Server-Sent Events (SSE) provides a unidirectional real-time communication channel from server to client over HTTP. Unlike WebSockets, SSE is built on standard HTTP and automatically handles reconnection.
+
+## Architecture
+
+### Components
+
+1. **SSE Service** (`services/sseService.js`)
+   - Manages client connections and topic subscriptions
+   - Provides methods for broadcasting and targeted messaging
+   - Handles automatic cleanup on disconnect
+
+2. **SSE Auth Middleware** (`middleware/sseAuth.js`)
+   - JWT authentication for SSE connections
+   - Supports token from query string, Authorization header, or x-auth-token header
+
+3. **SSE Routes** (`routes/sse.js`)
+   - `/api/sse/stream` - SSE stream endpoint
+   - `/api/sse/subscribe` - Subscribe to topics
+   - `/api/sse/unsubscribe` - Unsubscribe from topics
+
+## API Endpoints
+
+### GET /api/sse/stream
+
+Opens an SSE connection for the authenticated user.
+
+**Authentication:** Required (JWT via query parameter `?token=xxx` or Authorization header)
+
+**Response:** SSE stream with events
+
+**Example:**
+```javascript
+const token = localStorage.getItem('token');
+const eventSource = new EventSource(`/api/sse/stream?token=${token}`);
+
+eventSource.addEventListener('connected', (e) => {
+  console.log('Connected:', JSON.parse(e.data));
+});
+
+eventSource.addEventListener('notification', (e) => {
+  const data = JSON.parse(e.data);
+  console.log('Notification:', data);
+});
+
+eventSource.onerror = (error) => {
+  console.error('SSE Error:', error);
+};
+```
+
+### POST /api/sse/subscribe
+
+Subscribe to one or more topics.
+
+**Authentication:** Required
+
+**Body:**
+```json
+{
+  "topics": ["events", "posts", "notifications"]
+}
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "msg": "Subscribed to topics",
+  "topics": ["events", "posts", "notifications"]
+}
+```
+
+### POST /api/sse/unsubscribe
+
+Unsubscribe from topics.
+
+**Authentication:** Required
+
+**Body:**
+```json
+{
+  "topics": ["events"]
+}
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "msg": "Unsubscribed from topics",
+  "topics": ["events"]
+}
+```
+
+## SSE Service Methods
+
+### Client Management
+
+```javascript
+const sseService = require('./services/sseService');
+
+// Add a client (called automatically by /stream endpoint)
+sseService.addClient(userId, res);
+
+// Remove a client (called automatically on disconnect)
+sseService.removeClient(userId);
+```
+
+### Topic Subscriptions
+
+```javascript
+// Subscribe to topics
+sseService.subscribe(userId, ['events', 'posts']);
+
+// Unsubscribe from topics
+sseService.unsubscribe(userId, ['events']);
+```
+
+### Broadcasting Messages
+
+```javascript
+// Broadcast to all connected clients
+sseService.broadcast('announcement', {
+  message: 'System maintenance in 10 minutes'
+});
+
+// Broadcast to topic subscribers
+sseService.broadcastToTopic('events', 'eventUpdate', {
+  eventId: 123,
+  status: 'started'
+});
+
+// Send to specific user
+sseService.sendToUser(userId, 'notification', {
+  text: 'You have a new message',
+  priority: 'high'
+});
+```
+
+### Statistics
+
+```javascript
+// Get service statistics
+const stats = sseService.getStats();
+// Returns: { totalClients: 5, totalTopics: 3, topics: { events: 3, posts: 2, notifications: 5 } }
+```
+
+## Usage in Routes
+
+You can access the SSE service from any route handler:
+
+```javascript
+router.post('/events', auth, async (req, res) => {
+  try {
+    // Create event...
+    const event = await Event.create(req.body);
+    
+    // Notify subscribers via SSE
+    const sse = req.app.get('sse');
+    sse.broadcastToTopic('events', 'newEvent', {
+      eventId: event._id,
+      title: event.title,
+      date: event.date
+    });
+    
+    res.json({ success: true, event });
+  } catch (error) {
+    res.status(500).json({ success: false, msg: 'Server error' });
+  }
+});
+```
+
+## Event Types
+
+SSE messages are sent with specific event types. Clients can listen for specific event types:
+
+```javascript
+eventSource.addEventListener('newEvent', (e) => {
+  // Handle new event
+});
+
+eventSource.addEventListener('eventUpdate', (e) => {
+  // Handle event update
+});
+
+eventSource.addEventListener('notification', (e) => {
+  // Handle notification
+});
+```
+
+## Common Topics
+
+Recommended topic names for consistency:
+
+- `events` - Event creation, updates, deletions
+- `posts` - Social feed posts
+- `tasks` - Task updates
+- `notifications` - User notifications
+- `rewards` - Badge and reward notifications
+- `leaderboard` - Leaderboard changes
+
+## Message Format
+
+SSE messages follow this format:
+
+```
+event: eventType
+data: {"key": "value"}
+
+```
+
+The SSE service automatically formats messages correctly.
+
+## Connection Management
+
+- **Heartbeat:** The server sends a heartbeat comment (`:heartbeat`) every 30 seconds to keep the connection alive
+- **Auto-reconnect:** Browsers automatically reconnect if the connection is lost
+- **Cleanup:** Clients are automatically removed when the connection closes
+
+## Health Monitoring
+
+SSE statistics are included in the `/api/health` endpoint:
+
+```json
+{
+  "status": "healthy",
+  "services": {
+    "sse": {
+      "totalClients": 5,
+      "totalTopics": 3
+    }
+  }
+}
+```
+
+## Testing
+
+Run SSE tests:
+
+```bash
+npm test -- __tests__/routes/sse.test.js
+```
+
+Demo script:
+
+```bash
+node test-sse-demo.js
+```
+
+## Security
+
+- All SSE connections require JWT authentication
+- Tokens can be passed via query string (for EventSource compatibility) or headers
+- Connections are validated on connect; invalid tokens receive 401 Unauthorized
+- Each user can only have one active SSE connection (new connections replace old ones)
+
+## Performance Considerations
+
+- SSE uses HTTP/1.1 long-polling, so each connection uses one HTTP connection
+- Browser limit: ~6 connections per domain (HTTP/1.1)
+- For high-concurrency scenarios, consider using HTTP/2 (multiplexing) or WebSockets
+- The service is designed for low-memory usage with Map-based storage
+
+## Comparison with Socket.IO
+
+The backend supports both SSE and Socket.IO:
+
+| Feature | SSE | Socket.IO |
+|---------|-----|-----------|
+| Direction | Server → Client | Bidirectional |
+| Protocol | HTTP | WebSocket + HTTP fallback |
+| Browser Support | All modern browsers | All browsers |
+| Auto-reconnect | Built-in | Built-in |
+| Use Case | Server push notifications | Real-time chat, collaboration |
+
+**When to use SSE:**
+- Server needs to push updates to clients
+- Unidirectional communication is sufficient
+- Simpler setup and infrastructure
+
+**When to use Socket.IO:**
+- Bidirectional real-time communication needed
+- Complex event patterns
+- Existing Socket.IO infrastructure
+
+## Example: Complete Client Implementation
+
+```javascript
+class SSEClient {
+  constructor(token) {
+    this.token = token;
+    this.eventSource = null;
+    this.connected = false;
+  }
+
+  connect() {
+    this.eventSource = new EventSource(`/api/sse/stream?token=${this.token}`);
+    
+    this.eventSource.addEventListener('connected', (e) => {
+      console.log('SSE Connected:', JSON.parse(e.data));
+      this.connected = true;
+      this.subscribeToTopics(['events', 'notifications']);
+    });
+
+    this.eventSource.addEventListener('newEvent', (e) => {
+      const event = JSON.parse(e.data);
+      this.handleNewEvent(event);

+
+## Troubleshooting
+
+### Connection not established
+- Check that JWT token is valid and not expired
+- Verify token is passed correctly (query param or header)
+- Check browser console for CORS errors
+
+### Not receiving messages
+- Verify client is subscribed to the correct topics
+- Check that server is broadcasting to the correct topic
+- Ensure client is still connected (check `eventSource.readyState`)
+
+### High memory usage
+- Review the number of connected clients
+- Check for memory leaks in client connection handlers
+- Monitor SSE stats via `/api/health` endpoint

+# Kubernetes Configuration Review and Fixes
+
+## Date: December 5, 2025
+
+## Summary
+
+Comprehensive review and fixes applied to all Kubernetes deployment configurations in `/deploy/k8s/` directory to address namespace configuration, missing resources, environment variables, and other configuration issues.
+
+---
+
+## Issues Fixed
+
+### 1. **HIGH PRIORITY - Namespace Configuration**
+
+#### Issue
+- No `namespace.yaml` file existed
+- No namespace specified in any resource metadata
+- Documentation described manifests as "namespace-agnostic" which was error-prone
+
+#### Resolution
+- ✅ **Created** `namespace.yaml` to create `adopt-a-street` namespace
+- ✅ **Added** `namespace: adopt-a-street` to all resource metadata in:
+  - `backend-deployment.yaml` (Service and Deployment)
+  - `frontend-deployment.yaml` (Service and Deployment)
+  - `couchdb-statefulset.yaml` (Service and StatefulSet)
+  - `configmap.yaml`
+  - `secrets.yaml.example`
+  - `image-pull-secret.yaml`
+  - `ingress.yaml`
+
+---
+
+### 2. **MEDIUM PRIORITY - Duplicate Registry Secret Files**
+
+#### Issue
+- Two files creating the same secret `regcred`:
+  - `image-pull-secret.yaml` (template with placeholders)
+  - `registry-secret.yaml` (actual credentials - security risk!)
+
+#### Resolution
+- ✅ **Deleted** `registry-secret.yaml` (contained actual credentials)
+- ✅ **Kept** `image-pull-secret.yaml` as template
+- ✅ **Updated** documentation to guide users on creating the secret properly
+
+---
+
+### 3. **MEDIUM PRIORITY - CouchDB NODENAME Configuration**
+
+#### Issue
+- `couchdb-statefulset.yaml` line 71 had incorrect NODENAME format:
+  ```yaml
+  value: couchdb@0.adopt-a-street-couchdb  # INCORRECT
+  ```
+- Should follow StatefulSet pod naming: `<statefulset-name>-<ordinal>.<service-name>`
+
+#### Resolution
+- ✅ **Fixed** NODENAME to proper format:
+  ```yaml
+  value: couchdb@adopt-a-street-couchdb-0.adopt-a-street-couchdb
+  ```
+
+---
+
+### 4. **MEDIUM PRIORITY - Missing Environment Variables**
+
+#### Issue
+Missing environment variables required by `backend/.env.example`:
+- CouchDB connection pool settings
+- Stripe configuration (both secret and publishable keys)
+- OpenAI API configuration
+
+#### Resolution
+- ✅ **Added to `configmap.yaml`** (non-sensitive values):
+  - `COUCHDB_MAX_CONNECTIONS: "10"`
+  - `COUCHDB_REQUEST_TIMEOUT: "30000"`
+  - `STRIPE_PUBLISHABLE_KEY: "your-stripe-publishable-key"`
+  - `OPENAI_MODEL: "gpt-3.5-turbo"`
+
+- ✅ **Added to `secrets.yaml.example`** (sensitive values):
+  - `STRIPE_SECRET_KEY: "your-stripe-secret-key"`
+  - `OPENAI_API_KEY: "your-openai-api-key"`
+
+---
+
+### 5. **LOW PRIORITY - Duplicate Cloudinary Variables**
+
+#### Issue
+- Cloudinary variables duplicated in both `configmap.yaml` and `secrets.yaml.example`
+- `CLOUDINARY_CLOUD_NAME` and `CLOUDINARY_API_KEY` in both locations
+
+#### Resolution
+- ✅ **Removed** `CLOUDINARY_CLOUD_NAME` from `secrets.yaml.example` (kept in ConfigMap)
+- ✅ **Removed** `CLOUDINARY_API_KEY` comment from ConfigMap
+- ✅ **Organized** properly:
+  - **ConfigMap**: `CLOUDINARY_CLOUD_NAME` (non-sensitive)
+  - **Secrets**: `CLOUDINARY_API_KEY`, `CLOUDINARY_API_SECRET` (sensitive)
+
+---
+
+### 6. **LOW PRIORITY - Unused CouchDB ConfigMap**
+
+#### Issue
+- `couchdb-configmap.yaml` defined a ConfigMap but it was never mounted
+- CouchDB configuration generated inline via shell script in StatefulSet
+
+#### Resolution
+- ✅ **Deleted** `couchdb-configmap.yaml` (unused file)
+- Configuration approach remains inline in `couchdb-statefulset.yaml` (lines 102-124)
+
+---
+
+### 7. **MEDIUM PRIORITY - Documentation Updates**
+
+#### Issue
+- `DEPLOYMENT_GUIDE.md` described namespace-agnostic approach
+- Instructions required manual namespace specification with `-n` flag
+- No clear guidance on default namespace
+
+#### Resolution
+- ✅ **Updated** `DEPLOYMENT_GUIDE.md` with:
+  - Clear explanation that `adopt-a-street` is the default namespace
+  - Step-by-step deployment process including namespace creation
+  - Updated all example commands to use default namespace
+  - Comprehensive environment variables documentation
+  - Multi-environment deployment guidance
+  - Updated troubleshooting commands
+
+---
+

+
+---
+
+## Configuration Summary
+
+### Namespace Structure
+All resources now deploy to the `adopt-a-street` namespace by default. Alternative namespaces can still be used by overriding at deploy time.
+
+### ConfigMap Variables (`configmap.yaml`)
+```yaml
+# CouchDB
+COUCHDB_URL: "http://adopt-a-street-couchdb:5984"
+COUCHDB_DB_NAME: "adopt-a-street"
+COUCHDB_MAX_CONNECTIONS: "10"
+COUCHDB_REQUEST_TIMEOUT: "30000"
+
+# Application
+PORT: "5000"
+NODE_ENV: "production"
+FRONTEND_URL: "http://adopt-a-street.local"
+
+# Integrations (non-sensitive)
+CLOUDINARY_CLOUD_NAME: "your-cloudinary-cloud-name"
+STRIPE_PUBLISHABLE_KEY: "your-stripe-publishable-key"
+OPENAI_MODEL: "gpt-3.5-turbo"
+```
+
+### Secret Variables (`secrets.yaml.example`)
+```yaml
+# Authentication
+JWT_SECRET: "your-jwt-secret"
+
+# CouchDB
+COUCHDB_USER: "admin"
+COUCHDB_PASSWORD: "admin"
+COUCHDB_SECRET: "couchdb-secret"
+
+# Integrations (sensitive)
+CLOUDINARY_API_KEY: "your-api-key"
+CLOUDINARY_API_SECRET: "your-api-secret"
+STRIPE_SECRET_KEY: "your-stripe-secret"
+OPENAI_API_KEY: "your-openai-key"
+```
+
+---
+
+## Deployment Process
+
+### Quick Start (Recommended)
+```bash
+# 1. Create namespace
+kubectl apply -f deploy/k8s/namespace.yaml
+
+# 2. Create secrets file from example
+cp deploy/k8s/secrets.yaml.example deploy/k8s/secrets.yaml
+# Edit secrets.yaml with actual values
+
+# 3. Create image pull secret
+kubectl create secret docker-registry regcred \
+  --docker-server=gitea-gitea-http.taildb3494.ts.net \
+  --docker-username=will \
+  --docker-password=YOUR_PASSWORD \
+  --namespace=adopt-a-street
+
+# 4. Apply all configurations
+kubectl apply -f deploy/k8s/
+
+# 5. Verify deployment
+kubectl get all -n adopt-a-street
+```
+
+---
+
+## Verification
+
+### Health Checks
+All health check endpoints verified:
+- ✅ Backend: `/api/health` exists in `backend/server.js:150`
+- ✅ Frontend: `/health` exists in `frontend/nginx.conf:14`
+- ✅ CouchDB: `/_up` (standard CouchDB endpoint)
+
+### Service Discovery
+All service references verified:
+- ✅ ConfigMap references `adopt-a-street-couchdb:5984`
+- ✅ Ingress routes to `adopt-a-street-backend:5000` and `adopt-a-street-frontend:80`
+- ✅ Backend references ConfigMap `adopt-a-street-config` and Secret `adopt-a-street-secrets`
+
+---
+
+## Testing Checklist
+
+Before deploying to production:
+
+- [ ] Update `secrets.yaml` with actual secure values
+- [ ] Generate secure passwords using `openssl rand -base64 32`
+- [ ] Create image pull secret with actual Gitea credentials
+- [ ] Update `configmap.yaml` with actual Cloudinary cloud name
+- [ ] Update `ingress.yaml` with actual domain name
+- [ ] Verify storage class for CouchDB persistent volumes
+- [ ] Test deployment in development namespace first
+- [ ] Verify all pods reach Ready state
+- [ ] Test health endpoints
+- [ ] Verify CouchDB persistence after pod restart
+- [ ] Test ingress routing
+
+---
+
+## Security Notes
+
+1. **secrets.yaml** is in `.gitignore` - never commit to version control
+2. All production passwords should be generated with `openssl rand -base64 32`
+3. Image pull secrets contain credentials - handle securely
+4. Default CouchDB credentials are placeholders - MUST be changed for production
+5. Removed `registry-secret.yaml` which contained actual credentials
+
+---
+
+## Architecture Notes
+
+### Resource Placement
+- **CouchDB**: Required on ARM64 nodes (Pi 5) - uses `requiredDuringSchedulingIgnoredDuringExecution`
+- **Backend**: Preferred on ARM64 nodes (Pi 5) - uses `preferredDuringSchedulingIgnoredDuringExecution`
+- **Frontend**: No node affinity (lightweight, can run anywhere)
+
+### Storage
+- CouchDB uses StatefulSet with `volumeClaimTemplates`
+- 10Gi persistent storage per CouchDB pod
+- Storage class can be specified in `couchdb-statefulset.yaml:135`
+
+---
+
+## Next Steps (Optional)
+
+Consider adding these resources for production:
+1. **NetworkPolicy** - Restrict pod-to-pod communication
+2. **HorizontalPodAutoscaler** - Auto-scale based on metrics
+3. **PodDisruptionBudget** - Ensure availability during updates
+4. **ServiceAccount** - Dedicated service accounts per component
+5. **ResourceQuota** - Limit namespace resource usage
+6. **LimitRange** - Default resource limits for pods
+
+---
+
+## Rollback Plan
+
+If issues occur after deployment:
+
+```bash
+# Delete all resources
+kubectl delete -f deploy/k8s/
+
+# Or delete namespace (removes everything)
+kubectl delete namespace adopt-a-street
+
+# Revert to previous configuration
+git checkout HEAD~1 deploy/k8s/
+kubectl apply -f deploy/k8s/
+```

 ## Overview
-This guide covers the configuration changes needed to deploy Adopt-a-Street with CouchDB on the Raspberry Pi Kubernetes cluster. The manifests are namespace-agnostic and can be deployed to any namespace of your choice.
+This guide covers the configuration changes needed to deploy Adopt-a-Street with CouchDB on the Raspberry Pi Kubernetes cluster. All manifests are configured to use the `adopt-a-street` namespace by default.
 
-## Namespace Selection
+## Namespace Configuration
 
-### Choosing a Namespace
-Before deploying, decide which namespace to use:
-- **Development**: `adopt-a-street-dev` or `dev`
-- **Staging**: `adopt-a-street-staging` or `staging` 
-- **Production**: `adopt-a-street-prod` or `prod`
-- **Personal**: `adopt-a-street-<username>` for individual developers
+All Kubernetes resources are configured to deploy to the `adopt-a-street` namespace. A `namespace.yaml` file is included to create this namespace.
 
-### Namespace Best Practices
-- Use descriptive names that indicate environment purpose
-- Keep environments isolated in separate namespaces
-- Use consistent naming conventions across teams
-- Consider using prefixes like `adopt-a-street-` for clarity
-
-### Creating a Namespace
+### Creating the Namespace
 ```bash
-# Create a new namespace
-kubectl create namespace <your-namespace>
+# Create the adopt-a-street namespace using the provided manifest
+kubectl apply -f deploy/k8s/namespace.yaml
 
-# Set as default namespace for current context
-kubectl config set-context --current --namespace=<your-namespace>
+# Or create manually
+kubectl create namespace adopt-a-street
 
-# Or switch namespaces temporarily
-kubectl namespace <your-namespace>
+# Set as default namespace for current context (optional)
+kubectl config set-context --current --namespace=adopt-a-street
 ```
 
-## Changes Made
+### Alternative Namespaces
+If you want to deploy to a different namespace (e.g., for development or staging), you can override the namespace at apply time:
+```bash
+# Override namespace when applying
+kubectl apply -f deploy/k8s/ -n <your-namespace>
+```
 
-### 1. ConfigMap Updates (`configmap.yaml`)
-✅ Already configured for CouchDB:
-- `COUCHDB_URL`: "http://adopt-a-street-couchdb:5984"
-- `COUCHDB_DB_NAME`: "adopt-a-street"
-- Removed MongoDB references
+Note: When overriding namespaces, ensure the target namespace exists first.
 
-### 2. Secrets Configuration (`secrets.yaml`)
-✅ Generated secure credentials:
-- `JWT_SECRET`: Generated secure random token
-- `COUCHDB_USER`: "admin"
-- `COUCHDB_PASSWORD`: Generated secure random password
-- `COUCHDB_SECRET`: Generated secure random token
+### CouchDB Configuration
 
-### 3. Backend Deployment Updates (`backend-deployment.yaml`)
-✅ Updated configuration:
-- Image: `gitea-http.taildb3494.ts.net:will/adopt-a-street/backend:latest`
-- Added image pull secret for gitea registry
-- Environment variables configured for CouchDB
-- Health checks using `/api/health` endpoint
-- Resource limits optimized for Raspberry Pi 5 (ARM64)
+#### StatefulSet Configuration
+The CouchDB StatefulSet is configured with:
+- **Single-node mode**: Suitable for development and small production deployments
+- **Persistent storage**: 10Gi volume claim (configurable)
+- **ARM64 affinity**: Requires Raspberry Pi 5 nodes for better performance
+- **NODENAME**: Properly configured as `couchdb@adopt-a-street-couchdb-0.adopt-a-street-couchdb`
+- **Inline configuration**: CouchDB settings are generated via startup script
 
-### 4. Frontend Deployment Updates (`frontend-deployment.yaml`)
-✅ Updated configuration:
-- Image: `gitea-http.taildb3494.ts.net:will/adopt-a-street/frontend:latest`
-- Added image pull secret for gitea registry
-- Health checks using `/health` endpoint
-- Resource limits optimized for Raspberry Pi
+#### Storage Configuration
+```yaml
+volumeClaimTemplates:
+  - metadata:
+      name: couchdb-data
+    spec:
+      accessModes: ["ReadWriteOnce"]
+      resources:
+        requests:
+          storage: 10Gi
+```
 
-### 5. Image Pull Secret (`image-pull-secret.yaml`)
-✅ Created template for gitea registry authentication
+To change storage size, edit `couchdb-statefulset.yaml` line 133.
 
 ## Deployment Steps
 
-### 1. Create Image Pull Secret
+### 1. Create Namespace
 ```bash
-# Replace YOUR_GITEA_PASSWORD with your actual Gitea password
-# Replace <your-namespace> with your chosen namespace
-kubectl create secret docker-registry regcred \
-  --docker-server=gitea-http.taildb3494.ts.net \
-  --docker-username=will \
-  --docker-password=YOUR_GITEA_PASSWORD \
-  --namespace=<your-namespace>
+# Create the adopt-a-street namespace
+kubectl apply -f deploy/k8s/namespace.yaml
 
-# Examples:
-kubectl create secret docker-registry regcred \
-  --docker-server=gitea-http.taildb3494.ts.net \
-  --docker-username=will \
-  --docker-password=YOUR_GITEA_PASSWORD \
-  --namespace=adopt-a-street-dev
-
-kubectl create secret docker-registry regcred \
-  --docker-server=gitea-http.taildb3494.ts.net \
-  --docker-username=will \
-  --docker-password=YOUR_GITEA_PASSWORD \
-  --namespace=adopt-a-street-prod
+# Verify namespace creation
+kubectl get namespace adopt-a-street
 ```
 
-### 2. Apply Configuration
+### 2. Create Secrets
 ```bash
-# Apply all manifests to your chosen namespace
-kubectl apply -f deploy/k8s/ -n <your-namespace>
+# Copy the example secrets file
+cp deploy/k8s/secrets.yaml.example deploy/k8s/secrets.yaml
 
-# Or apply individually for more control:
-kubectl apply -f deploy/k8s/configmap.yaml -n <your-namespace>
-kubectl apply -f deploy/k8s/secrets.yaml -n <your-namespace>
-kubectl apply -f deploy/k8s/couchdb-statefulset.yaml -n <your-namespace>
-kubectl apply -f deploy/k8s/backend-deployment.yaml -n <your-namespace>
-kubectl apply -f deploy/k8s/frontend-deployment.yaml -n <your-namespace>
+# Edit secrets.yaml and replace all placeholder values
+# IMPORTANT: Generate secure values for production using:
+# openssl rand -base64 32
 
-# Examples for different environments:
-kubectl apply -f deploy/k8s/ -n adopt-a-street-dev
-kubectl apply -f deploy/k8s/ -n adopt-a-street-staging  
-kubectl apply -f deploy/k8s/ -n adopt-a-street-prod
+# Apply the secrets
+kubectl apply -f deploy/k8s/secrets.yaml
 ```
 
-### 3. Verify Deployment

+  --docker-server=gitea-gitea-http.taildb3494.ts.net \
+  --docker-username=will \
+  --docker-password=YOUR_GITEA_PASSWORD \
+  --namespace=adopt-a-street
 
-# Check services in your namespace
-kubectl get services -n <your-namespace>
+# Or use the template file (after updating with your credentials)

 ### Multi-Environment Deployment
 
-#### Deploying to Multiple Namespaces
+#### Using Different Namespaces for Environments
+While the default namespace is `adopt-a-street`, you can override it for different environments:
+
 ```bash
-# Deploy to development
+# Deploy to development namespace
+kubectl create namespace adopt-a-street-dev
 kubectl apply -f deploy/k8s/ -n adopt-a-street-dev
 
-# Deploy to staging  
+# Deploy to staging namespace
+kubectl create namespace adopt-a-street-staging
 kubectl apply -f deploy/k8s/ -n adopt-a-street-staging
 
-# Deploy to production
-kubectl apply -f deploy/k8s/ -n adopt-a-street-prod
-
-# Compare deployments across namespaces
-kubectl get deployments --all-namespaces | grep adopt-a-street
+# Deploy to production (uses default namespace)
+kubectl apply -f deploy/k8s/
 ```
 
-#### Environment-Specific Configuration
-```bash
-# Create environment-specific secrets
-kubectl create secret generic jwt-secret-dev --from-literal=JWT_SECRET=$(openssl rand -base64 32) -n adopt-a-street-dev
-kubectl create secret generic jwt-secret-prod --from-literal=JWT_SECRET=$(openssl rand -base64 32) -n adopt-a-street-prod
+#### Customizing Per Environment
+For environment-specific configurations, create custom ConfigMaps and Secrets:
 
-# Patch ConfigMaps for different environments
-kubectl patch configmap adopt-a-street-config -n adopt-a-street-prod \
-  --patch '{"data":{"NODE_ENV":"production"}}'
+```bash
+# Create environment-specific ConfigMap
+kubectl create configmap adopt-a-street-config \
+  --from-literal=NODE_ENV=development \
+  --from-literal=FRONTEND_URL=http://dev.adopt-a-street.local \
+  -n adopt-a-street-dev
+
+# Create environment-specific secrets
+kubectl create secret generic adopt-a-street-secrets \
+  --from-literal=JWT_SECRET=$(openssl rand -base64 32) \
+  -n adopt-a-street-dev
