Kubernetes Linkerd和k8s不工作

我正试图了解库伯内特斯的Linkeder。我正在使用LinkedDeamonset示例，该示例来自他们在我的本地

minikube

它都部署在

生产

命名空间中。当我试图

http_proxy=$(kubectl --namespace=production get svc l5d -o jsonpath="{.status.loadBalancer.ingress[0].*}"):4140 curl -s http://apiserver/readinezs

什么也没发生。我的设置哪里出了问题

我的链接yaml：

以下是我对apiservice的部署：

        resources:
          limits:
            memory: "300Mi"
            cpu: "50m"
        imagePullPolicy: Always
        command:
        - "pm2-docker"
        - "processes.json"
        ports:

        args:
        - proxy
        - "-p"
        - "8001"

服务内容如下：

kind: Service
apiVersion: v1
metadata:
  name: apiserver
spec:
  selector:
    app: apiserver
    role: gateway
  type: LoadBalancer
  ports:
  - name: http
    port: 8080
  - name: external
    port: 80
    targetPort: 8080

在我的节点应用程序中，我使用的是

全局隧道

：

const server = app.listen(port);
server.on('listening', function(){

  // make sure all traffic goes over linkerd
  globalTunnel.initialize({
    host: 'localhost',
    port: 4140
  });

 console.log(`Feathers application started on ${app.get('host')}:${app.get('port')} `);

部署两个相同的节点应用程序，并让它们相互发送请求，这是可行的。奇怪的是，这些请求没有出现在linkerd仪表板中。

您的

curl

命令在哪里运行

本例中的链接器服务不公开公共IP地址。您可以通过

kubectl get svc/l5d

确认这一点——我希望您不会看到任何外部IP

---

我认为您需要修改服务定义，或者创建一个额外的显式外部服务来公开

ClusterIP

，以便接收入口流量。
