从外部Pod到集群内部访问kubernetics服务

Question

Am running several services on same port within my kubernetes cluster; 我在kubernetes集群中的同一端口上运行多个服务； so its like ser1, ser2, ser3 all using same port 8080. I can access these services from inside a pod as <serv-name>:8080 but can I also access them in same way from one of the host nodes ie outside a container but from one of the cluster nodes ? 所以它像ser1，ser2，ser3都使用相同的端口8080。我可以从Pod内部以<serv-name>:8080访问这些服务，但是我也可以从主机节点之一（即容器外部）以相同的方式访问它们但是从群集节点之一？

I tried looking around but did not find any relevant discussion on this. 我尝试环顾四周，但未找到任何相关讨论。 Pls if someone may suggest. 请有人建议。

my sample config 我的样本配置

apiVersion: v1
kind: Service
metadata:
  name: svc1
  namespace: sample
  labels:
    app: svc1
spec:
  selector:
    app: app1
  ports:
  - name: psvc1
    port: 8080
    targetPort: 9090
    protocol: TCP

as Dries said, using cluster IP we can access the service from node. 正如Dries所说，使用群集IP，我们可以从节点访问服务。

kubectl run nginx --image=nginx --port=80 --expose=true

kubectl  get svc
NAME         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1        <none>        443/TCP   9d
nginx        ClusterIP   10.103.206.246   <none>        80/TCP    52m


# curl 10.103.206.246:80
