【k8s】k8s pv pvc 的删除和重建

从上到下：

1. 停掉引用pvc的微服务实例
2. 删掉pvc
3. 删掉pv

# kubectl get pvc  -A

# kubectl  scale  deployment   XXXX  --replicas=0  -n  test

# kubectl  delete pod  XXX  --grace-period=0   --force    -n test


# kubectl  delete pvc  test01  -n test
# kubectl  delete pvc  test01  --grace-period=0  --force  -n test

从下到上：

1 创建pv
2 创建pvc
3 创建微服务实例，引用pvc

#  kubctl create  -f   test_pv.yaml
#  kubctl create  -f  test_pvc.yaml

# kubectl  scale  deployment   XXXX  --replicas=2  -n  test
