Go-Chassis

Go-Chassis is a microservice framework for rapid development of microservices in Go

Features

• Pluggable registrator and discovery service: Support Service center, istio pilot, kubernetes and file based registry, fit both client side discovery and server side discovery pattern
• Pluggable Protocol: You can custom your own protocol, by default support http and grpc
• Multiple server management: you can separate API by protocols and ports
• Circuit breaker: Protect your micro service system in runtime
• Route management: Able to route to different service based on weight and match rule to achieve Canary Release easily
• Client side Load balancing: Able to custom strategy
• Rate limiting: Both client side and server side rate limiting
• Pluggable Cipher: Able to custom your own cipher for AKSK and TLS certs
• Handler Chain: Able to add your own code during service calling for client and server side
• Metrics: Able to expose Prometheus metric API automatically and custom metrics reporter
• Tracing:Use opentracing-go as standard library, easy to integrate tracing impl
• Logger: You can custom your own writer to sink log, by default support file and stdout
• Hot-reconfiguraion: Powered by go-archaius, configurations can be reload in runtime, like load balancing, circuit breaker, rate limiting
• Dynamic Configuration framework: Powered by go-archaius, developer is able to develop a service which has hot-reconfiguration feature easily
• Fault Injection: In consumer side, you can inject faults to bring chaos testing into your system

Quick Start

You can see more documentations in here

1. Install go 1.10+

2. Clone the project

git clone git@github.com:go-chassis/go-chassis.git

3. Use go mod(go 1.11+, experimental but a recommended way)

cd go-chassis
GO111MODULE=on go mod download
#optional
GO111MODULE=on go mod vendor

4. Install service-center

5. Write your first http micro service

Examples

Communication Protocols

Go-Chassis supports 3 types of communication protocol.

1. Rest - REST is an approach that leverages the HTTP protocol for communication.
2. Highway - This is a RPC communication protocol, it was deprecated.
3. grpc - native grpc protocol, go chassis bring circuit breaker, route management etc to grpc.

Debug suggestion for dlv:

Add -tags debug into go build arguments before debugging, if your go version is go1.10 onward.

example:

go build -tags debug -o server -gcflags "all=-N -l" server.go

Chassis customized debug tag to resolve dlv debug issue:
