# Deployment Automation Summary

**Last Updated**: 2025-01-27  
**Status**: Complete automation framework created

---

## Overview

A comprehensive automation framework has been created to automate the deployment process following the 15-phase deployment guide. The automation includes:

- ✅ **18 executable scripts** covering all deployment phases
- ✅ **Centralized configuration** in `config.sh`
- ✅ **State management** for resumable deployments
- ✅ **Comprehensive logging** for troubleshooting
- ✅ **Error handling** and validation at each step

---

## Scripts Created

### Main Orchestrator
- **`deploy.sh`** - Main deployment script with phase orchestration

### Configuration
- **`config.sh`** - Centralized configuration and utility functions

### Phase Scripts (15 phases)
1. **`phase1-prerequisites.sh`** - Development environment setup
2. **`phase2-azure-infrastructure.sh`** - Terraform infrastructure deployment
3. **`phase3-entra-id.sh`** - Entra ID configuration (manual steps)
4. **`phase4-database-storage.sh`** - Database and storage setup
5. **`phase5-container-registry.sh`** - Container registry configuration
6. **`phase6-build-package.sh`** - Build and package applications
7. **`phase7-database-migrations.sh`** - Database migrations
8. **`phase8-secrets.sh`** - Secrets configuration
9. **`phase9-infrastructure-services.sh`** - Infrastructure services deployment
10. **`phase10-backend-services.sh`** - Backend services deployment
11. **`phase11-frontend-apps.sh`** - Frontend applications deployment
12. **`phase12-networking.sh`** - Networking and gateways
13. **`phase13-monitoring.sh`** - Monitoring and observability
14. **`phase14-testing.sh`** - Testing and validation
15. **`phase15-production.sh`** - Production hardening

### Helper Scripts
- **`store-entra-secrets.sh`** - Store Entra ID secrets in Key Vault

---

## Quick Start

### Full Deployment

```bash
# Deploy all phases for dev environment
./scripts/deploy/deploy.sh --all --environment dev

# Deploy with auto-apply (no Terraform review)
./scripts/deploy/deploy.sh --all --environment dev --auto-apply
```

### Incremental Deployment

```bash
# Run specific phases
./scripts/deploy/deploy.sh --phase 1 --phase 2 --phase 6

# Continue from last state
./scripts/deploy/deploy.sh --continue
```

### Individual Phase Execution

```bash
# Run a specific phase
./scripts/deploy/phase1-prerequisites.sh
./scripts/deploy/phase6-build-package.sh
./scripts/deploy/phase10-backend-services.sh
```

---

## Features

### ✅ Automated Steps

The following phases are fully automated:

1. **Phase 1**: Prerequisites checking and setup
2. **Phase 2**: Azure infrastructure (Terraform)
3. **Phase 4**: Database and storage configuration
4. **Phase 5**: Container registry setup
5. **Phase 6**: Build and package (Docker images)
6. **Phase 7**: Database migrations
7. **Phase 8**: Secrets management (partial)
8. **Phase 9**: Infrastructure services (External Secrets, Prometheus)
9. **Phase 10**: Backend services deployment
10. **Phase 11**: Frontend applications deployment
11. **Phase 12**: Networking (Ingress, cert-manager)
12. **Phase 13**: Monitoring (Application Insights, Log Analytics)
13. **Phase 14**: Testing (health checks, integration tests)
14. **Phase 15**: Production hardening

### ⚠️ Manual Steps Required

Some steps still require manual configuration:

- **Phase 3**: Entra ID setup in Azure Portal (use `store-entra-secrets.sh` after)
- **Phase 8**: Some secrets need manual input
- **Phase 12**: DNS configuration
- **Phase 12**: SSL certificate setup (cert-manager installed, but ClusterIssuer needs config)
- **Phase 13**: Alert rules and dashboard configuration

---

## Configuration

### Environment Variables

Set these before running deployment:

```bash
export ENVIRONMENT=dev              # dev, stage, prod
export AZURE_REGION=westeurope      # Azure region
export ACR_NAME=theorderacr         # Container registry name
export AKS_NAME=the-order-dev-aks   # AKS cluster name
export KEY_VAULT_NAME=the-order-dev-kv  # Key Vault name
```

### Configuration File

Edit `scripts/deploy/config.sh` for default values:

```bash
readonly ENVIRONMENT="${ENVIRONMENT:-dev}"
readonly AZURE_REGION="${AZURE_REGION:-westeurope}"
readonly ACR_NAME="${ACR_NAME:-${PROJECT_NAME}acr}"
```

---

## State Management

Deployment state is automatically saved to `.deployment/${ENVIRONMENT}.state`:

```json
{
  "phase": "phase10",
  "step": "complete",
  "timestamp": "2025-01-27T12:00:00Z"
}
```

This allows:
- Resuming from last completed phase
- Tracking deployment progress
- Debugging failed deployments

---

## Logging

All deployment logs are saved to `logs/deployment-YYYYMMDD-HHMMSS.log`:

```bash
# View latest log
tail -f logs/deployment-*.log

# Search logs
grep "ERROR" logs/deployment-*.log
```

---

## Error Handling

- Scripts use `set -euo pipefail` for strict error handling
- Failed phases are logged and tracked
- Option to continue after failures
- State saved after each successful phase

---

## Integration with CI/CD

The scripts can be integrated into CI/CD pipelines:

```yaml
# .github/workflows/deploy.yml
- name: Deploy to Dev
  run: |
    ./scripts/deploy/deploy.sh --all --environment dev --auto-apply
  env:
    AZURE_CREDENTIALS: ${{ secrets.AZURE_CREDENTIALS }}
    ENVIRONMENT: dev
```

---

## Next Steps

1. **Review Configuration**: Edit `scripts/deploy/config.sh` for your environment
2. **Set Environment Variables**: Configure Azure credentials and resource names
3. **Run Prerequisites**: `./scripts/deploy/deploy.sh --phase 1`
4. **Deploy Infrastructure**: `./scripts/deploy/deploy.sh --phase 2`
5. **Complete Manual Steps**: Follow deployment guide for Phases 3 and 8
6. **Continue Deployment**: `./scripts/deploy/deploy.sh --continue`
