Service 服务发现(Cluster IP & NodePo
Cluster IP
1.创建Service
root@k8s-master:~# kubectl expose deployment maydep --port=8080 --target-port=80
service/maydep exposed
2.查看Service
root@k8s-master:~# kubectl get service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 41h
maydep ClusterIP 10.102.112.40 <none> 8080/TCP 49s
3.测试服务的可用性
root@k8s-master:~# curl 10.102.112.40:8080
<html><body><h1>It works!</h1></body></html>
root@k8s-master:~#
4.删除服务
root@k8s-master:~# kubectl delete service maydep
service "maydep" deleted
root@k8s-master:~# kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 42h
NodePort
1.创建NodePort Service
root@k8s-master:~# kubectl expose deployment maydep --port=8080 --target-port=80 --type=NodePort
service/maydep exposed
2.查看Service
root@k8s-master:~# kubectl get service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 42h
maydep NodePort 10.110.234.148 <none> 8080:32591/TCP 2m49s
3.浏览器访问对应信息，IP为node/master的IP + 端口为32591
