应用部署

[root@k8s-1 nfs-provisioner]# kubectl apply -f sa.yaml 

[root@k8s-1 nfs-provisioner]# kubectl apply -f deploy.yaml

[root@k8s-1 nfs-provisioner]# kubectl apply -f  storageclass.yaml

[root@k8s-1 nfs-provisioner]# kubectl get pod  |grep nfs

[root@k8s-1 nfs-provisioner]# kubectl apply -f nginx_sts_pvc.yaml 
service/nginx created
statefulset.apps/web created

[root@k8s-1 nfs-provisioner]# kubectl get pod -A |grep web
default       web-0                                     1/1     Running   0               44s
default       web-1                                     1/1     Running   0               41s

自动创建pv,pvc

[root@k8s-1 nfs-provisioner]# kubectl get pv,pvc |grep web
persistentvolume/pvc-1a4130ff-4c42-48b2-af27-2eac30b90e96   10Mi       RWO            Delete           Bound    default/www-web-0      nfs-storage             13h

[root@k8s-1 nfs-provisioner]# kubectl get svc |grep nginx
nginx        ClusterIP   None             <none>        80/TCP         3m43s

[root@k8s-1 nfs-provisioner]# curl  web-1.nginx.default.svc.cluster.local
web-1
[root@k8s-1 nfs-provisioner]# curl  web-0.nginx.default.svc.cluster.local
