一、kubernetes资源查看方式：查看pod

### --- 可以通过get ns查看当前节点下有多少个namespace；

[root@k8s-master01 ~]# kubectl get ns
NAME                   STATUS   AGE
default                Active   4d23h
kube-node-lease        Active   4d23h
kube-public            Active   4d23h
kube-system            Active   4d23h
kubernetes-dashboard   Active   4d21h

### --- 若是不指定-n默认是default命名空间的，当前default是没有任何资源的

[root@k8s-master01 ~]# kubectl get po
No resources found in default namespace.

### --- 查看当前环境有多少个pod当前的pod都是通过namespace隔离的。

[root@k8s-master01 ~]# kubectl get po -n kube-system
NAME                                       READY   STATUS    RESTARTS   AGE
calico-kube-controllers-5f6d4b864b-6clrl   1/1     Running   0          4d22h
calico-node-6hbtl                          1/1     Running   14         4d22h
calico-node-77c2f                          1/1     Running   6          4d22h
calico-node-hrqpt                          1/1     Running   0          4d22h
calico-node-trkhw                          1/1     Running   16         4d22h
calico-node-z4gkj                          1/1     Running   0          4d22h
coredns-867d46bfc6-sk5dp                   1/1     Running   1          4d21h
metrics-server-595f65d8d5-slhtd            1/1     Running   12         4d21h

二、PV查看说明

### --- PV是没有namespace隔离性的，RBAC是没有namespace隔离性的

[root@k8s-master01 ~]# kubectl get clusterrole
NAME                                                                   CREATED AT
admin                                                                  2021-04-09T13:52:18Z
calico-kube-controllers                                                2021-04-09T15:13:24Z
calico-node                                                            2021-04-09T15:13:24Z
cluster-admin                                                          2021-04-09T13:52:18Z
edit                                                                   2021-04-09T13:52:18Z
kubernetes-dashboard                                                   2021-04-09T16:07:07Z

三、查看ClusterRole

### --- 查看ClusterRole

[root@k8s-master01 ~]# kubectl get clusterrole -n kube-system
NAME                                                                   CREATED AT
admin                                                                  2021-04-09T13:52:18Z
calico-kube-controllers                                                2021-04-09T15:13:24Z
calico-node                                                            2021-04-09T15:13:24Z
cluster-admin                                                          2021-04-09T13:52:18Z

四、查看StorageClass

### --- StorageClass也是没有namespace隔离的

[root@k8s-master01 ~]# kubectl get storageclass

五、查看ingressclass

### --- ingressclass也是没有namesapce隔离的
~~~     service/ingress/HPA/ConfigMap/Secret/Volume/CronJob/Taint&Toleration、
~~~     InitContainer/Affinity/EphemeralContainers都是有namespace隔离的。

[root@k8s-master01 ~]# kubectl get ingressclass

六、查看secret

### --- 查看secret 
~~~     针对不同的namespace查看到的结果是不一样的。

[root@k8s-master01 ~]# kubectl get secret
NAME                  TYPE                                  DATA   AGE
default-token-6d2lx   kubernetes.io/service-account-token   3      4d23h
[root@k8s-master01 ~]# kubectl get secret -n kube-system
NAME                                             TYPE                                  DATA   AGE
admin-user-token-nh8n7                           kubernetes.io/service-account-token   3      4d21h
attachdetach-controller-token-bgkqs              kubernetes.io/service-account-token   3      4d23h
