我在谷歌云上有一个名为 blog-dev 的 kubernetes 集群，在 us-central1-c 区域中有 3 个 N1-g1 小实例。我通过以下方式配置了我的集群

  1. 键入命令“gcloud init”。选择账户、项目和地区
  2. 键入命令“gcloud container clusters get-credentials blog-dev”
  3. 输入命令'kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.3/deploy/static/provider/cloud/deploy.yaml'
  4. 转到 GCloud 中的负载均衡器部分并复制负载均衡器 ip
  5. 将条目 'load-balancer-ip' blog.dev 放入 hosts.ini 文件中。将负载均衡器 ip 替换为第 4 步中的 IP
  6. 输入命令'kubectl create secret generic jwt-secret --from-literal=JWT_KEY=asdf'
  7. 键入命令“skaffold dev”。为此所需的文件可以在下面找到

我在 nats-test/src 中创建了一个 publisher.ts

import nats from 'node-nats-streaming';
const stan = nats.connect('posts','abc',{
    url:'http://nats-srv:4222'
});

stan.on('connect',()=>{
    console.log('Publisher connected to nats');
})

我已经使用脚本部分中显示的条目更新了 package.json

"scripts": {
    "publish": "ts-node-dev --notify false src/publisher.ts",
    "listen": "ts-node-dev --notify false src/listener.ts"
  }

当我运行“npm run publish”时，出现如下所示的错误

NatsError: Could not connect to server: Error: connect ETIMEDOUT 216.239.36.21:4222
    at Socket.<anonymous> (/home/meanjsbpb/BPB_MEAN_Framework/node_modules/nats/lib/nats.js:833:26)
    at Socket.emit (events.js:223:5)
    at emitErrorNT (internal/streams/destroy.js:92:8)
    at emitErrorAndCloseNT (internal/streams/destroy.js:60:3)

[ERROR] 12:48:47 NatsError: Could not connect to server: Error: connect ETIMEDOUT 216.239.36.21:4222

NATS 监控页面可以从谷歌云网络预览中看到，并且 URL 是https://8222-cs-131594183002-default.cs-asia-southeast1-ajrg.cloudshell.dev/?authuser=1但是当我尝试从使用 http://nats-srv:8222 的浏览器，它显示“页面未显示”。

请帮忙！！！
