and this little reverse proxy logic for 5601 (kibana) and (9200) ES:

github.com

andrewarrow/gnr/blob/21e4e878ae3425f3792ddba263bfcc2d561a31c9/main.go#L76


      
          		//r.Paths["login"] = app.Login
          		//r.Paths["register"] = app.Register
          		//r.Paths["admin"] = app.Admin
          		r.Paths["markup"] = router.Markup
          		r.BucketPath = "/Users/aa/bucket"
          		r.ListenAndServe(":" + "3000")
          	} else if arg == "help" {
          	}
          }
          
          func handleRequest(writer http.ResponseWriter, request *http.Request) {
          	path := request.URL.Path
          	target := "http://127.0.0.1:3000"
          
          	if strings.Contains(path, "kibana") {
          		target = "http://127.0.0.1:5601"
          	} else if strings.Contains(path, "esprefix") {
          		path = strings.ReplaceAll(path, "/esprefix", "")
          		target = "http://127.0.0.1:9200"
          	}

My app runs on 8080 and that’s all fly needs to know in fly.toml but go will look for request.URL.Path of kibana or esprefix and intercept.
