Load Balancer
Let’s Create a Simple Load Balancer With Go - kasvith.me
func lb(w http.ResponseWriter, r *http.Request) {
attempts := GetAttemptsFromContext(r)
if attempts > 3 {
log.Printf("%s(%s) Max attempts reached, terminating\n", r.RemoteAddr, r.URL.Path)
http.Error(w, "Service not available", http.StatusServiceUnavailable)
return
}
peer := serverPool.GetNextPeer()
if peer != nil {
peer.ReverseProxy.ServeHTTP(w, r)
return
}
http.Error(w, "Service not available", http.StatusServiceUnavailable)
}
