📁 Files¶

main.bicep - Minimal infrastructure (App Service + PostgreSQL only)
main.bicep.backup - Original Container Apps configuration
main.parameters.json - Simplified parameters
main.parameters.json.backup - Original parameters
app/app-service.bicep - App Service module (B1 tier)
app/db-postgres-minimal.bicep - Minimal PostgreSQL configuration

🚀 Deployment Steps¶

1. Build and Push Docker Image to Docker Hub¶

# Login to Docker Hub
docker login

# Build the image
cd /Users/bamr87/github/barodybroject
docker build -t bamr87/barodybroject:latest -f src/Dockerfile src/

# Push to Docker Hub
docker push bamr87/barodybroject:latest

2. Set Environment Variables¶

# Ensure required variables are set
azd env set DB_PASSWORD "your-secure-password"
azd env set DOCKER_IMAGE "bamr87/barodybroject:latest"

3. Deploy Infrastructure¶

# Provision infrastructure
azd provision

# Or full deployment
azd up

🔧 What Changed¶

Removed (Cost Savings):¶

❌ Azure Container Registry (~$5/month)
❌ Container Apps Environment (~$6/month)
❌ Key Vault (~$0.50/month)
❌ Application Insights (~$2-5/month)
❌ Monitoring Dashboard (~$1/month)

Added (Minimal Cost):¶

✅ App Service Plan B1 ($13.14/month)
✅ App Service (Linux container support)

Kept (No Change):¶

✅ PostgreSQL Flexible Server B1ms ($12.41/month)
✅ Resource Group (free)

📊 Infrastructure Components¶

App Service (B1 Tier)¶

Cost: $13.14/month
Resources: 1 vCPU, 1.75 GB RAM
Storage: 10 GB
Features:
Docker container support
Custom domains & SSL
Auto-scaling (vertical)
99.95% SLA

PostgreSQL Flexible Server (Burstable B1ms)¶

Cost: $12.41/month
Resources: 1 vCPU, 2 GiB RAM
Storage: 32 GB (minimum)
Features:
7-day backup retention
Point-in-time restore
99.9% SLA

🔄 Rolling Back¶

If you need to revert to the original infrastructure:

# Restore original files
cp infra/main.bicep.backup infra/main.bicep
cp infra/main.parameters.json.backup infra/main.parameters.json

# Re-deploy
azd up

📈 Scaling Up Later¶

When your traffic grows, you can easily scale:

Vertical Scaling (App Service)¶

# Upgrade to S1 tier (2 cores, 3.5 GB RAM)
az appservice plan update --name <plan-name> --resource-group <rg-name> --sku S1

Horizontal Scaling (Database)¶

# Upgrade to General Purpose tier
az postgres flexible-server update --name <server-name> --resource-group <rg-name> --tier GeneralPurpose --sku-name Standard_D2s_v3

Re-add Services¶

Uncomment sections in main.bicep to add: - Key Vault for advanced secret management - Application Insights for detailed monitoring - Container Registry for private images

🛠️ Troubleshooting¶

Issue: Docker image not found¶

Solution: Ensure image is pushed to Docker Hub and is public, or configure Docker Hub credentials in App Service.

Issue: Database connection fails¶

Solution: Check firewall rules in PostgreSQL allow Azure services (0.0.0.0).

Issue: App Service not starting¶

Solution: 1. Check logs: az webapp log tail --name <app-name> --resource-group <rg-name> 2. Verify WEBSITES_PORT=8000 is set 3. Ensure Dockerfile exposes port 8000

📞 Support¶

For issues or questions: 1. Check Azure Portal diagnostics 2. Review App Service logs 3. Verify Docker image works locally 4. Check PostgreSQL connection from local machine

🎯 Next Steps¶

✅ Deploy the minimal infrastructure
Monitor costs in Azure Cost Management
Set up alerts for unexpected cost increases
Consider Azure Reserved Instances for 30% additional savings
Plan for scaling when traffic increases

Estimated Monthly Cost: ~$25.55 USD **Previous Cost**: ~$32-37 USD Savings: 30-40% reduction
