servicekit-go

servicekit for golang

servicekit is a simple, minimum viable service management library for golang.

Quick Start

• get library

  go get github.com/servicekit/servicekit-go              (>=go1.8)
  

• coordinator service

   co, err := coordinator.NewConsul("127.0.0.1:8500", "http", "", log)
   if err != nil {
       panic(err)
   }
  
   // Get Services
   services, meta, error:= co.GetServices(context.Background(), "service name", "tag string")
   ...
  
   // Register service
   err := co.Register(context.Background(), spec.Service{ID: "nginx1", Service: "nginx"})
   ...
  
   // Deregister service
   err := co.Deregister(context.Background(), "service_id")
   ...
  
  

• grpc load balance

  grpc load balance was implemented by https://github.com/grpc/grpc/blob/master/doc/load-balancing.md

   co, err := coordinator.NewConsul("127.0.0.1:8500", "http", "", log)
   if err != nil {
       panic(err)
   }
  
   b, err := balancer.NewConsulBalancer(co, "account_service", "", log)
   if err != nil {
       panic(err)
   }
  
   r := b.GetResolver(context.Background())
  
   conn, err := grpc.Dial(
       "",
       grpc.WithBalancer(grpc.RoundRobin(r)))
   ...
  
  

• grpc invoke fault tolerant

     i := invoker.NewFailoverInvoker(10, time.Second, invoker.NewFibDelay(time.Second))
     err := i.Invoke(context.Background(), conn, "/Account/Auth", authRequest, authResponse)
     ...
