From 00a672d12e0e275e609c2cc59d76b2f204e4b3de Mon Sep 17 00:00:00 2001 From: chrislu Date: Fri, 12 Sep 2025 08:46:03 -0700 Subject: [PATCH] Add comprehensive Docker Compose setup for Kafka integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. --- test/kafka/Dockerfile.kafka-gateway | 56 +++ test/kafka/Dockerfile.test-setup | 38 ++ test/kafka/Makefile | 203 ++++++++++

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
