具有Istio服务的Minikube不可用（http状态503）Node.js连接到Etcd

我一直在研究一个简单的Node.js应用程序，它使用Istio来设置和获取来自etcd的密钥，将两个服务连接在一起 . 我尝试了一些变化但仍然看到返回相同的错误 .

nodeAppTesting失败（etcd-operator） - > {“errors”：[{“server”：“http：// etcd-operator：2379”，“httperror”：null，“httpstatus”：503，“httpbody”：“上游连接错误或断开/重置之前 Headers “，”响应“：{”statusCode“：503，”正文“：”上游连接错误或断开/重置 Headers 之前“，” Headers “：{”content-length“：” 57“，”content-type“：”text / plain“，”date“：”星期四，2017年6月8日17:17:04 GMT“，”服务器“：”envoy“，”x-envoy-upstream-service-时间 “：” 5 “}，” 请求 “：{” URI “：{” 协议 “：” HTTP：”， “斜线”：真 “AUTH”：空， “宿主”： “ETCD运算符：2379” “端口”： “2379”， “主机名”： “ETCD运营商”， “散”：空， “搜索”：空， “查询”：空， “路径”： “/ V2 /按键/密押” “路径”： “/ V2 /键/密押”， “HREF”： “HTTP：// ETCD运算符：2379 / V2 /键/密押”}， “方法”： “GET”， “报头”：{”接受 “：” 应用/ JSON “}}}，” 时间戳 “：” 2017-06-08T17：17：04.544Z “}]，” 重试“：0}

查看代理日志，我可以看到客户端和服务器代理都参与了通信（这在我看到服务器头中的envoy时已经过验证） .

附加Node.js应用程序和deployment.yaml . server.js

var http = require('http');
var Etcd = require('node-etcd');
var fs = require('fs');
var httpClient = require('request');

var handleRequest = function(request, response) {


    var scheme = "http";
    var ipAddress = "etcd-operator"
    var port = "2379";
    var connectionAddress = scheme +"://" + ipAddress +":" + port;

    console.log('Received request for URL: ' + request.url + " connecting to " + connectionAddress);
    var etcd = new Etcd([connectionAddress] /*, options */);
    etcd.set("testKey" , "foo");
    etcd.get("testKey", function(err, res){
        if(!err){
            response.writeHead(200);
            response.write("nodeAppTesting("+ ipAddress+") ->"+ JSON.stringify(res) ) ;
            response.end();
        }else{
            response.writeHead(500);
            response.write("nodeAppTesting failed("+ ipAddress+") ->"+ JSON.stringify(err) ) ;
            console.log("Encountered error during runtime", JSON.stringify(err));
            response.end();
        }
    });

}
var www = http.createServer(handleRequest);
www.listen(8080);
console.log("App up and running on port 8080")
