Question

我使用OS Centos 7。我的Pod：

forloop.index0

我的服务：

apiVersion: v1
kind: Pod
metadata:
  name: tomcat
spec:
  containers:
  - image: ec2-73-99-254-8.eu-central-1.compute.amazonaws.com:5000/tom
    name: tomcat
    command: ["sh","-c","/opt/tomcat/bin/deploy-and-run.sh"]
    volumeMounts:
    - mountPath: /maven
      name: app-volume
    ports:
    - containerPort: 8080
  volumes:
  - name: app-volume
    hostPath:
      path: /maven

服务看起来像：

apiVersion: v1
kind: Service
metadata:
  name: tomcat
spec:
  ports:
    - name: http
      port: 80
      targetPort: 8080
      protocol: TCP
  selector:
    name: tomcat

和Pods：

# kubectl get svc
NAME         CLUSTER_IP      EXTERNAL_IP   PORT(S)   SELECTOR      AGE
kubernetes   10.254.0.1      <none>        443/TCP   <none>        14h
tomcat       10.254.206.26   <none>        80/TCP    name=tomcat   13h

当我运行Curl：

# kubectl get pod
NAME      READY     STATUS    RESTARTS   AGE
tomcat    1/1       Running   0          13h

当时的Kube代理日志显示如下：

curl 10.254.206.26
curl: (56) Recv failure: Connection reset by peer

但是当我直接将curl运行到pod ip地址和端口8080时 - 它运行正常。当我运行命令kube-proxy[22273]: Couldn't find an endpoint for default/tomcat:http: missing service entry kube-proxy[22273]: Failed to connect to balancer: missing service entry

时

kubectl get endpoints

此输出中的字段ENDPOINTS使用＆＃34; none＆＃34;看起来很奇怪怎么了？

Answer 1

服务通过匹配标签来工作。您正尝试根据您的广告连播的名称进行匹配。尝试将您的广告连播的元数据更改为

metadata:
  name: tomcat
  labels:
    name: tomcat

看看是否有帮助。

kube-proxy无法找到默认/ tomcat的端点：http：缺少服务条目
