Question 1

How to deploy Go Micro services to Kubernetes?

Accepted Answer

Go Micro focuses on systemd deployment via its CLI, but you can containerize services manually; however, it lacks native Kubernetes integration, so you'll need to handle service discovery and configuration yourself, which might require extra work compared to frameworks designed for K8s.

Question 2

Go Micro vs gRPC for microservices in Go?

Accepted Answer

Go Micro includes RPC with built-in service discovery and load balancing, while gRPC is just a communication protocol. Go Micro is more comprehensive for distributed systems, but gRPC might be lighter if you only need RPC and plan to manage other concerns separately.

Question 3

How to use Go Micro with PostgreSQL for data storage?

Accepted Answer

Use the data model layer by defining structs with tags, then initialize the service with a Postgres backend via micro.Model() option; the README shows examples with SQLite, and similar setup applies for Postgres with appropriate DSN configuration.

Question 4

What is the performance overhead of Go Micro's reflection usage?

Accepted Answer

The framework uses reflection for dynamic message encoding and other features, which can add latency in high-performance scenarios; the README acknowledges this with a reflection evaluation document, so benchmark for your use case if speed is critical.

Question 5

Can I use Go Micro for a single service without microservices?

Accepted Answer

Yes, but it's overkill—Go Micro's abstractions like service discovery are unnecessary for a single service, and simpler frameworks like Gin or Echo would be more lightweight and faster to set up for basic HTTP APIs.

Question 6

How does MCP integration work in Go Micro?

Accepted Answer

Services are automatically exposed as MCP tools via a built-in gateway; run with 'micro run' to get an agent playground and tools registry, and connect any MCP-compatible agent to the HTTP endpoint without additional code.

Question 7

Is Go Micro production-ready for large-scale systems?

Accepted Answer

Yes, it's used by companies like Sourse for mission-critical SaaS, but ensure you're comfortable with its systemd deployment model and reflection-based performance; review the security and performance docs for optimization tips.
