Awesome Nomad › Demo and Learning Resources
The project "go-coffeeshop" is a practical event-driven microservices demo application built using Golang. It simulates a coffee shop environment with multiple microservices that interact in an event-driven manner. The application is designed to demonstrate modern microservices architecture and deployment practices using a variety of HashiCorp tools and other infrastructure components. The project leverages HashiCorp Nomad for orchestration and deployment, Consul Connect for service mesh and service discovery, Vault for secrets management, and Terraform for infrastructure as code deployment. The microservices architecture includes several services such as grpc-gateway, product service, counter service, barista service, kitchen service, and a web frontend. These services communicate using gRPC and RabbitMQ for messaging, showcasing a choreography saga pattern for managing distributed transactions. The backend stack includes popular Golang libraries and tools such as grpc-gateway, Echo web framework, RabbitMQ client, sqlc for SQL generation, and various utilities for logging, configuration, and dependency injection. The infrastructure stack includes PostgreSQL as the database, RabbitMQ as the message broker, and Docker for containerization. The project also provides a reproducible development environment using devcontainers. The repository includes detailed documentation on how to deploy the application using the HashiCorp stack, including Nomad, Consul Connect, Vault, and Terraform. It also provides instructions for local development and debugging. The project follows clean domain-driven design principles and aims to enhance microservices development with features like testing, observability, user identity management, and resiliency in future updates. Overall, "go-coffeeshop" serves as a comprehensive example for developers looking to build and deploy event-driven microservices applications using Golang and HashiCorp tools.
