# 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/
```

# CouchDB Deployment Configuration Guide # CouchDB Deployment Configuration Guide
## Overview ## 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 All Kubernetes resources are configured to deploy to the `adopt-a-street` namespace. A `namespace.yaml` file is included to create this 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
### Namespace Best Practices ### Creating the Namespace
- 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
```bash ```bash
# Create a new namespace # Create the adopt-a-street namespace using the provided manifest
kubectl create namespace <your-namespace> kubectl apply -f deploy/k8s/namespace.yaml
# Set as default namespace for current context # Or create manually
kubectl config set-context --current --namespace=<your-namespace> kubectl create namespace adopt-a-street
# Or switch namespaces temporarily # Set as default namespace for current context (optional)
kubectl namespace <your-namespace> 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`) Note: When overriding namespaces, ensure the target namespace exists first.
✅ Already configured for CouchDB:
- `COUCHDB_URL`: "http://adopt-a-street-couchdb:5984"
- `COUCHDB_DB_NAME`: "adopt-a-street"
- Removed MongoDB references
### 2. Secrets Configuration (`secrets.yaml`) ### CouchDB Configuration
✅ Generated secure credentials:
- `JWT_SECRET`: Generated secure random token
- `COUCHDB_USER`: "admin"
- `COUCHDB_PASSWORD`: Generated secure random password
- `COUCHDB_SECRET`: Generated secure random token
### 3. Backend Deployment Updates (`backend-deployment.yaml`) #### StatefulSet Configuration
✅ Updated configuration: The CouchDB StatefulSet is configured with:
- Image: `gitea-http.taildb3494.ts.net:will/adopt-a-street/backend:latest` - **Single-node mode**: Suitable for development and small production deployments
- Added image pull secret for gitea registry - **Persistent storage**: 10Gi volume claim (configurable)
- Environment variables configured for CouchDB - **ARM64 affinity**: Requires Raspberry Pi 5 nodes for better performance
- Health checks using `/api/health` endpoint - **NODENAME**: Properly configured as `couchdb@adopt-a-street-couchdb-0.adopt-a-street-couchdb`
- Resource limits optimized for Raspberry Pi 5 (ARM64) - **Inline configuration**: CouchDB settings are generated via startup script
### 4. Frontend Deployment Updates (`frontend-deployment.yaml`) #### Storage Configuration
✅ Updated configuration: ```yaml
- Image: `gitea-http.taildb3494.ts.net:will/adopt-a-street/frontend:latest` volumeClaimTemplates:
- Added image pull secret for gitea registry - metadata:
- Health checks using `/health` endpoint name: couchdb-data
- Resource limits optimized for Raspberry Pi spec:
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 10Gi
```
### 5. Image Pull Secret (`image-pull-secret.yaml`) To change storage size, edit `couchdb-statefulset.yaml` line 133.
✅ Created template for gitea registry authentication
## Deployment Steps ## Deployment Steps
### 1. Create Image Pull Secret ### 1. Create Namespace
```bash ```bash
# Replace YOUR_GITEA_PASSWORD with your actual Gitea password # Create the adopt-a-street namespace
# Replace <your-namespace> with your chosen namespace kubectl apply -f deploy/k8s/namespace.yaml

--docker-server=gitea-http.taildb3494.ts.net \
--docker-username=will \
--docker-password=YOUR_GITEA_PASSWORD \
--namespace=<your-namespace>
# Examples: # Verify namespace creation
kubectl create secret docker-registry regcred \ kubectl get namespace adopt-a-street
--docker-server=gitea-http.taildb3494.ts.net \
--docker-username=will \
--docker-password=YOUR_GITEA_PASSWORD \

```bash ```bash
# Apply all manifests to your chosen namespace # Copy the example secrets file
kubectl apply -f deploy/k8s/ -n <your-namespace> cp deploy/k8s/secrets.yaml.example deploy/k8s/secrets.yaml
# Or apply individually for more control: # Edit secrets.yaml and replace all placeholder values
kubectl apply -f deploy/k8s/configmap.yaml -n <your-namespace> # IMPORTANT: Generate secure values for production using:
kubectl apply -f deploy/k8s/secrets.yaml -n <your-namespace> # openssl rand -base64 32
kubectl apply -f deploy/k8s/couchdb-statefulset.yaml -n <your-namespace>
kubectl apply -f deploy/k8s/backend-deployment.yaml -n <your-namespace>

### Multi-Environment Deployment ### 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 ```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 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 kubectl apply -f deploy/k8s/ -n adopt-a-street-staging
# Deploy to production # Deploy to production (uses default namespace)
kubectl apply -f deploy/k8s/ -n adopt-a-street-prod kubectl apply -f deploy/k8s/
# Compare deployments across namespaces
kubectl get deployments --all-namespaces | grep adopt-a-street
``` ```
#### Environment-Specific Configuration #### Customizing Per Environment
```bash For environment-specific configurations, create custom ConfigMaps and Secrets:
# Create environment-specific secrets
kubectl create secret generic jwt-secret-dev --from-literal=JWT_SECRET=$(openssl rand -base64 32) -n adopt-a-street-dev
