* Initial plan
* feat(health): add RegistryCheck for registry connectivity health checks
Add a RegistryCheck function to the health package that creates a health
check verifying connectivity to the service registry. This enables
Kubernetes readiness probes to detect when a service loses its connection
to the registry (e.g. etcd).
Usage:
health.Register("registry", health.RegistryCheck(reg))
* fix(health): simplify error assertion in registry check test

Go Micro Examples
This directory contains runnable examples demonstrating various go-micro features and patterns.
Quick Start
Each example can be run with go run . from its directory.
Examples
hello-world
Basic RPC service demonstrating core concepts:
- Service creation and registration
- Handler implementation
- Client calls
- Health checks
Run it:
cd hello-world
go run .
web-service
HTTP web service with service discovery:
- HTTP handlers
- Service registration
- Health checks
- JSON REST API
Run it:
cd web-service
go run .
multi-service
Multiple services in a single binary — the modular monolith pattern:
- Isolated server, client, store, and cache per service
- Shared registry and broker for inter-service communication
- Coordinated lifecycle with
service.Group - Start monolith, split later when you need to scale independently
Run it:
cd multi-service
go run .
deployment
Docker Compose deployment with MCP gateway, Consul registry, and Jaeger tracing:
- Production-like architecture in one
docker-compose up - Standalone MCP gateway connected to service registry
- Distributed tracing with OpenTelemetry + Jaeger
MCP Examples
See the mcp/ directory for AI agent integration examples:
- hello - Minimal MCP service (start here)
- crud - CRUD contact book with full agent documentation
- workflow - Cross-service orchestration via AI agents
- documented - All MCP features with auth scopes
agent-demo
Multi-service project management app (Projects, Tasks, Team) with seed data and agent playground integration.
agent-plan-delegate
The two built-in agent capabilities in a small multi-agent system:
- plan — an agent records an ordered plan in its store-backed memory before doing multi-step work
- delegate — an agent hands a subtask to another agent (over RPC if it's registered, else to an ephemeral sub-agent)
Coming Soon
- pubsub-events - Event-driven architecture with NATS
- grpc-integration - Using go-micro with gRPC
Prerequisites
Some examples require external dependencies:
- NATS:
docker run -p 4222:4222 nats:latest - Consul:
docker run -p 8500:8500 consul:latest agent -dev -ui -client=0.0.0.0 - Redis:
docker run -p 6379:6379 redis:latest
Contributing
To add a new example:
- Create a new directory
- Add a descriptive README.md
- Include working code with comments
- Add to this index
- Ensure it runs with
go run .
