Kubernetes 安装 Nginx以及配置自动补全

部署 Nginx ：

[root@k8s-master ~]# kubectl create deployment nginx --image=nginx:1.14-alpine
deployment.apps/nginx created

暴露端口：

[root@k8s-master ~]# kubectl expose deployment nginx --port=80 --type=NodePort
service/nginx exposed

查看服务状态：

[root@k8s-master ~]# kubectl get pods,svc
NAME                         READY   STATUS    RESTARTS   AGE
pod/nginx-65c4bffcb6-f9b55   1/1     Running   0          61sNAME                 TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
service/kubernetes   ClusterIP   10.96.0.1      <none>        443/TCP        45h
service/nginx        NodePort    10.96.67.225   <none>        80:31339/TCP   16s[root@k8s-master ~]# kubectl get pod
NAME                     READY   STATUS    RESTARTS   AGE
nginx-65c4bffcb6-f9b55   1/1     Running   0          3m17s
[root@k8s-master ~]# kubectl get service
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP   10.96.0.1      <none>        443/TCP        45h
nginx        NodePort    10.96.67.225   <none>        80:31339/TCP   2m39s

使用master主节点ip地址访问nginx：

使用集群IP访问：

[root@k8s-master ~]# kubectl get pods,svc
NAME                         READY   STATUS    RESTARTS   AGE
pod/nginx-65c4bffcb6-f9b55   1/1     Running   0          61sNAME                 TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
service/kubernetes   ClusterIP   10.96.0.1      <none>        443/TCP        45h
service/nginx        NodePort    10.96.67.225   <none>        80:31339/TCP   16s
[root@k8s-master ~]# curl -X GET 10.96.67.225
