1.查看namespace
[root@k8s-master1 ~]# kubectl get namespaces # namespaces可以简写namespace或ns
NAME STATUS AGE
default Active 130m # 所有未指定Namespace的对象都会被默认分配在default命名空间
kube-node-lease Active 130m
kube-public Active 130m # 此命名空间下的资源可以被所有人访问
kube-system Active 130m # 所有由Kubernetes系统创建的资源都处于这个命名空间
2.查看namespace里的资源
kubectl get all --namespace=kube-system

3.创建namespace
3.1.命令创建
kubectl create namespace ns1
namespace/ns1 created
[root@k8s-master1 ~]# kubectl get ns
NAME STATUS AGE
default Active 5d1h
kube-node-lease Active 5d1h
kube-public Active 5d1h
kube-system Active 5d1h
ns1 Active 10s
3.2.yaml文件创建
vim create_ns2.yml
apiVersion: v1
kind: Namespace
metadata:
name: ns2
使用kubectl apply -f 创建
kubectl apply -f create_ns2.yml
namespace/ns2 created
查看
kubectl get ns
NAME STATUS AGE
default Active 5d2h
kube-node-lease Active 5d2h
kube-public Active 5d2h
kube-system Active 5d2h
ns1 Active 10m
ns2 Active 46s
4.删除namespace
4.1.命令删除
# kubectl delete namespace ns1
namespace "ns1" deleted
4.2.YAML文件删除
# kubectl delete -f create_ns2.yml
namespace "ns2" deleted
