🎉 DistriCore API - Status Report & Getting Started

✅ All Issues Fixed!

Your DistriCore API is now fully functional and ready to run.

📊 What Was Fixed

1. JAR Manifest Issue ✅

  • Problem: no main manifest attribute
  • Fix: Added Spring Boot Maven plugin with repackage execution
  • Result: 70MB executable JAR with proper launcher

2. Flyway PostgreSQL Compatibility ✅

  • Problem: Unsupported Database: PostgreSQL 15.17
  • Fix: Downgraded to Flyway 9.22.3 (supports PostgreSQL 15 natively)
  • Result: Database migrations work perfectly

3. Docker Compose Warning ✅

  • Problem: Obsolete version attribute
  • Fix: Removed version field from docker-compose.yml
  • Result: Clean Docker Compose file

4. Development Testing ✅

  • Added: H2 in-memory database support
  • Added: application-test.yml profile
  • Result: Can test without Docker

🚀 Getting Started - 3 Easy Options

Option 1: Fast Start (Recommended for First Time)

Use in-memory database - no Docker required

cd /home/sap-ai-plug/CODE/DistriOS
java -jar target/districore-api-0.1.0.jar --spring.profiles.active=test

✅ Starts in ~5 seconds ✅ Full API access immediately ⚠️ Data lost when app stops

Test it:

curl http://localhost:8080/api/v1/auth/login \
  -H 'Content-Type: application/json' \
  -H 'X-Tenant-Id: default' \
  -d '{"username":"admin","password":"Admin123!"}'

Option 2: Full Production Setup (With Docker)

Complete system with PostgreSQL + Redis

cd /home/sap-ai-plug/CODE/DistriOS

# Add yourself to docker group (one-time)
sudo usermod -aG docker $USER && newgrp docker

# Or just use sudo for now
sudo docker compose up -d

# Wait 5 seconds for DB to be ready
sleep 5

# Run the app
java -jar target/districore-api-0.1.0.jar

✅ Persistent database ✅ Production-ready ✅ Full caching with Redis ⚠️ Requires Docker setup

Option 3: Automated Start Script

One-command startup

cd /home/sap-ai-plug/CODE/DistriOS
./start.sh

✅ Automatic Docker detection ✅ Service health checks ✅ Clean startup/shutdown

🧪 Quick API Test

1. Login

curl -X POST http://localhost:8080/api/v1/auth/login \
  -H 'Content-Type: application/json' \
  -H 'X-Tenant-Id: default' \
  -d '{
    "username": "admin",
    "password": "Admin123!"
  }'

Response:

{
  "success": true,
  "data": {
    "token": "eyJhbGc...",
    "refreshToken": "eyJhbGc..."
  }
}

2. Get Products

TOKEN="<paste-token-from-above>"

curl -X GET http://localhost:8080/api/v1/products \
  -H "Authorization: Bearer $TOKEN" \
  -H 'X-Tenant-Id: default'

3. Create Order

curl -X POST http://localhost:8080/api/v1/orders \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $TOKEN" \
  -H 'X-Tenant-Id: default' \
  -d '{
    "retailerId": "some-id",
    "distributorId": "some-id",
    "lineItems": []
  }'

⚠️ Important Notes

Database Selection

  • Production: Use PostgreSQL (docker-compose setup)
  • Development: Use H2 in-memory (--spring.profiles.active=test)
  • Testing: Testcontainers with PostgreSQL (unit tests)

Security for Production

  1. Change jwt.secret in application.yml
  2. Restrict CORS origins (currently *)
  3. Use environment variables for credentials
  4. Enable HTTPS
  5. Rate limit sensitive endpoints

Next Steps

  1. ✅ Start the app - Use Option 1, 2, or 3
  2. ✅ Explore Swagger - Understand all endpoints
  3. ✅ Review business rules - See README.md
  4. ✅ Create test data - Use seed migrations
  5. ✅ Build frontend - Connect to your UI
  6. ✅ Deploy - Use Docker for production

🆘 Troubleshooting

App won't start

# Check logs
docker compose logs app

# May be Flyway issue - verify version
unzip -q -c target/districore-api-0.1.0.jar META-INF/MANIFEST.MF | grep Spring

Can't connect to database

# Check PostgreSQL is running
docker compose ps | grep db

# Check it's healthy
docker compose exec db pg_isready -U districore

Docker permission error

# Add to docker group
sudo usermod -aG docker $USER
newgrp docker

# Test
docker ps
