# Infrastructure Cleanup Summary

**Date:** 2026-01-07
**Action:** Removed legacy Docker Compose infrastructure files

---

## Deleted Directories and Files

The following legacy infrastructure files have been removed as they were specific to Docker Compose deployment and are **not used** in the Kubernetes deployment:

### ❌ Removed:
- `infrastructure/pgadmin/` - pgAdmin configuration for Docker Compose
  - `pgpass` - Password file
  - `servers.json` - Server definitions
  
- `infrastructure/postgres/` - PostgreSQL configuration for Docker Compose
  - `init-scripts/init.sql` - Database initialization
  
- `infrastructure/rabbitmq/` - RabbitMQ configuration for Docker Compose
  - `definitions.json` - Queue/exchange definitions
  - `rabbitmq.conf` - RabbitMQ settings
  
- `infrastructure/redis/` - Redis configuration for Docker Compose
  - `redis.conf` - Redis settings
  
- `infrastructure/terraform/` - Terraform infrastructure-as-code (unused)
  - `base/`, `dev/`, `staging/`, `production/` directories
  - `modules/` directory
  
- `infrastructure/rabbitmq.conf` - Standalone RabbitMQ config file

### ✅ Retained:

#### `infrastructure/kubernetes/`
**Purpose:** Complete Kubernetes deployment manifests
**Status:** Active and required
**Contents:**
- `base/` - Base Kubernetes resources
  - `components/` - All service deployments
  - `databases/` - Database deployments (uses embedded configs)
  - `monitoring/` - Prometheus, Grafana, AlertManager
  - `migrations/` - Database migration jobs
  - `secrets/` - TLS secrets and application secrets
  - `configmaps/` - PostgreSQL logging config
- `overlays/` - Environment-specific configurations
  - `dev/` - Development overlay
  - `prod/` - Production overlay
- `encryption/` - Kubernetes secrets encryption config

#### `infrastructure/tls/`
**Purpose:** TLS/SSL certificates for database encryption
**Status:** Active and required
**Contents:**
- `ca/` - Certificate Authority (10-year validity)
  - `ca-cert.pem` - CA certificate
  - `ca-key.pem` - CA private key (KEEP SECURE!)
- `postgres/` - PostgreSQL server certificates (3-year validity)
  - `server-cert.pem`, `server-key.pem`, `ca-cert.pem`
- `redis/` - Redis server certificates (3-year validity)
  - `redis-cert.pem`, `redis-key.pem`, `ca-cert.pem`
- `generate-certificates.sh` - Certificate generation script

---

## Why These Were Removed

### Docker Compose vs Kubernetes

The removed files were configuration files for **Docker Compose** deployments:
- pgAdmin was used for local database management (not needed in prod)
- Standalone config files (rabbitmq.conf, redis.conf, postgres init scripts) were mounted as volumes in Docker Compose
- Terraform was an unused infrastructure-as-code attempt

### Kubernetes Uses Different Approach

Kubernetes deployment uses:
- **ConfigMaps** instead of config files
- **Secrets** instead of environment files
- **Kubernetes manifests** instead of docker-compose.yml
- **Built-in orchestration** instead of Terraform

**Example:**
```yaml
# OLD (Docker Compose):
volumes:
  - ./infrastructure/rabbitmq/rabbitmq.conf:/etc/rabbitmq/rabbitmq.conf

# NEW (Kubernetes):
env:
  - name: RABBITMQ_DEFAULT_USER
    valueFrom:
      secretKeyRef:
        name: rabbitmq-secrets
        key: RABBITMQ_USER
```

---

## Verification

### No References Found
Searched entire codebase and confirmed **zero references** to removed folders:
```bash
grep -r "infrastructure/pgadmin" --include="*.yaml" --include="*.sh"
# No results

grep -r "infrastructure/terraform" --include="*.yaml" --include="*.sh"
# No results
```

### Kubernetes Deployment Unaffected
- All services use Kubernetes ConfigMaps and Secrets
- Database configs embedded in deployment YAML files
- TLS certificates managed via Kubernetes Secrets (from `infrastructure/tls/`)

## Impact Assessment

### ✅ No Breaking Changes
- Kubernetes deployment unchanged
- All services continue to work
- TLS certificates still available
- Production readiness maintained

### ✅ Benefits
- Cleaner repository structure
- Less confusion about which configs are used
- Faster repository cloning (smaller size)
- Clear separation: Kubernetes-only deployment

### ✅ Documentation Updated
- [PILOT_LAUNCH_GUIDE.md](../docs/PILOT_LAUNCH_GUIDE.md) - Uses only Kubernetes
- [PRODUCTION_OPERATIONS_GUIDE.md](../docs/PRODUCTION_OPERATIONS_GUIDE.md) - References only K8s resources
- [infrastructure/kubernetes/README.md](kubernetes/README.md) - K8s-specific documentation

---

## Rollback (If Needed)

If for any reason you need these files back, they can be restored from git:

```bash
# View deleted files
git log --diff-filter=D --summary | grep infrastructure

# Restore specific folder (example)
git checkout HEAD~1 -- infrastructure/pgadmin/

# Or restore all deleted infrastructure
git checkout HEAD~1 -- infrastructure/
```

**Note:** You won't need these for Kubernetes deployment. They were Docker Compose specific.
