二、创建secrets

### --- 创建secretsyaml文件

[root@k8s-master01 NodeJS]# kubectl edit secrets registrykey -n nodejs-test
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
