K8s 报错 Unsupported value: "rbac.authorization.k8s.io": supported values: ""

K8s 报错 Unsupported value: "rbac.authorization.k8s.io": supported values: ""

问题现象

# kubectl apply -f role-devops.yml
Warning: rbac.authorization.k8s.io/v1beta1 RoleBinding is deprecated in v1.17+, unavailable in v1.22+; use rbac.authorization.k8s.io/v1 RoleBinding
The RoleBinding "RoleBinding-devops" is invalid: subjects[0].apiGroup: Unsupported value: "rbac.authorization.k8s.io": supported values: ""

 分析原因

根据报错应该是rbac.authorization.k8s.io字段不支持，支持“”,替换后解决
