Add comprehensive Docker Compose setup for Kafka integration tests

MAJOR ENHANCEMENT: Complete Docker-based integration testing infrastructure ## New Docker Compose Infrastructure: - docker-compose.yml: Complete multi-service setup with health checks - Apache Kafka + Zookeeper - Confluent Schema Registry - SeaweedFS full stack (Master, Volume, Filer, MQ Broker, MQ Agent) - Kafka Gateway service - Test setup and utility services ## Docker Services: - Dockerfile.kafka-gateway: Custom Kafka Gateway container - Dockerfile.test-setup: Schema registration and test data setup - kafka-gateway-start.sh: Service startup script with dependency waiting - wait-for-services.sh: Comprehensive service readiness verification ## Test Setup Utility: - cmd/setup/main.go: Automated schema registration utility - Registers User, UserEvent, and LogEntry Avro schemas - Handles service discovery and health checking ## Integration Tests: - docker_integration_test.go: Comprehensive Docker-based integration tests - Kafka connectivity and topic operations - Schema Registry integration - Kafka Gateway functionality - Sarama and kafka-go client compatibility - Cross-client message compatibility - Performance benchmarking ## Build and Test Infrastructure: - Makefile: 30+ targets for development and testing - setup, test-unit, test-integration, test-e2e - Performance testing and benchmarking - Individual service management - Debugging and monitoring tools - CI/CD integration targets ## Documentation: - README.md: Comprehensive documentation - Architecture overview and service descriptions - Quick start guide and development workflow - Troubleshooting and performance tuning - CI/CD integration examples ## Key Features: ✅ Complete service orchestration with health checks ✅ Automated schema registration and test data setup ✅ Multi-client compatibility testing (Sarama, kafka-go) ✅ Performance benchmarking and monitoring ✅ Development-friendly debugging tools ✅ CI/CD ready with proper cleanup ✅ Comprehensive documentation and examples ## Usage: make setup-schemas # Start all services and register schemas make test-e2e # Run end-to-end integration tests make clean # Clean up environment This provides a production-ready testing infrastructure that ensures Kafka Gateway compatibility with real Kafka ecosystems and validates schema registry integration in realistic deployment scenarios.

+# Kafka Integration Testing with Docker Compose
+
+This directory contains comprehensive integration tests for SeaweedFS Kafka Gateway using Docker Compose to set up all required dependencies.
+
+## Overview
+
+The Docker Compose setup provides:
+- **Apache Kafka** with Zookeeper
+- **Confluent Schema Registry** for schema management
+- **SeaweedFS** complete stack (Master, Volume, Filer, MQ Broker, MQ Agent)
+- **Kafka Gateway** that bridges Kafka protocol to SeaweedFS MQ
+- **Test utilities** for schema registration and data setup
+
+## Quick Start
+
+### Prerequisites
+
+- Docker and Docker Compose
+- Go 1.21+
+- Make (optional, for convenience)
+
+### Basic Usage
+
+1. **Start the environment:**
+   ```bash
+   make setup-schemas
+   ```
+   This starts all services and registers test schemas.
+
+2. **Run integration tests:**
+   ```bash
+   make test-integration
+   ```
+
+3. **Run end-to-end tests:**
+   ```bash
+   make test-e2e
+   ```
+
+4. **Clean up:**
+   ```bash
+   make clean
+   ```
+

+## Test Configuration
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `KAFKA_BOOTSTRAP_SERVERS` | `localhost:9092` | Kafka broker addresses |
+| `KAFKA_GATEWAY_URL` | `localhost:9093` | Kafka Gateway address |
+| `SCHEMA_REGISTRY_URL` | `http://localhost:8081` | Schema Registry URL |

+
+### Running Tests with Custom Configuration
+
+```bash
+KAFKA_BOOTSTRAP_SERVERS=localhost:9092 \
+KAFKA_GATEWAY_URL=localhost:9093 \
+SCHEMA_REGISTRY_URL=http://localhost:8081 \
+go test -v ./test/kafka/ -run Integration
+```
+
+## Test Schemas
+
+The setup automatically registers these test schemas:
+
+### User Schema
+```json
+{
+  "type": "record",
+  "name": "User",
+  "fields": [
+    {"name": "id", "type": "int"},
+    {"name": "name", "type": "string"},
+    {"name": "email", "type": ["null", "string"], "default": null}
+  ]
+}
+```
+
+### User Event Schema
+```json
+{
+  "type": "record",
+  "name": "UserEvent",
+  "fields": [
+    {"name": "userId", "type": "int"},
+    {"name": "eventType", "type": "string"},
+    {"name": "timestamp", "type": "long"},
+    {"name": "data", "type": ["null", "string"], "default": null}
+  ]
+}
+```
+
+### Log Entry Schema
+```json
+{
+  "type": "record",
+  "name": "LogEntry",
+  "fields": [
+    {"name": "level", "type": "string"},
+    {"name": "message", "type": "string"},
+    {"name": "timestamp", "type": "long"},
+    {"name": "service", "type": "string"},
+    {"name": "metadata", "type": {"type": "map", "values": "string"}}
+  ]
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Services not starting:**
+   ```bash
+   make status
+   make debug
+   ```
+
+2. **Port conflicts:**
+   - Check if ports 2181, 8081, 9092, 9093, etc. are available
+   - Modify `docker-compose.yml` to use different ports if needed
+
+3. **Schema Registry connection issues:**
+   ```bash
+   curl http://localhost:8081/subjects
+   make logs-schema-registry
+   ```
+
+4. **Kafka Gateway not responding:**
+   ```bash
+   nc -z localhost 9093
+   make logs-gateway
+   ```
+
+5. **Test timeouts:**
+   - Increase `TEST_TIMEOUT` environment variable
+   - Check service health with `make status`
+
+### Performance Tuning
+
+For better performance in testing:
+
+1. **Increase Docker resources:**
+   - Memory: 4GB+
+   - CPU: 2+ cores
+
+2. **Adjust Kafka settings:**
+   - Modify `docker-compose.yml` Kafka environment variables
+   - Tune partition counts and replication factors
+
+3. **SeaweedFS optimization:**
+   - Adjust volume size limits
+   - Configure appropriate replication settings
+
+## CI/CD Integration
+
+### GitHub Actions Example
+
+```yaml

+
+## Contributing
+
+When adding new tests:
+
+1. **Follow naming conventions:**
+   - Integration tests: `TestDockerIntegration_*`
+   - Unit tests: `Test*_Unit`
+   - Performance tests: `TestDockerIntegration_Performance`
+
+2. **Use environment variables:**
+   - Check for required environment variables
+   - Skip tests gracefully if dependencies unavailable
+
+3. **Clean up resources:**
+   - Use unique topic names with timestamps
+   - Clean up test data after tests
+
+4. **Add documentation:**
+   - Update this README for new test categories
+   - Document any new environment variables or configuration
