kubectl get svc

test-pod           NodePort    10.98.13.86      <none>        3001:30001/TCP
another-pod           NodePort    10.110.208.135   <none>        3000:30001/TCP

# 进入容器 test-pod
$ sudo kubectl exec -it test-pod /bin/sh

# 请求 another-pod
/ # wget 10.110.208.135:3000
Connecting to 10.110.208.135:3000 (10.110.208.135:3000)
wget: server returned error: HTTP/1.1 401

# 注：返回 401 说明网络通了

# 接下来请求自己的服务
/ # wget 10.98.13.86:3001
Connecting to 10.98.13.86:3001 (10.98.13.86:3001)
# 无响应

# 不写地址写 localhost 是通的
/ # wget localhost:3001
Connecting to localhost:3001 (localhost:3001)
wget: server returned error: HTTP/1.1 401
