7.6. 向用户添加角色

流程

1. 向指定项目中的用户添加角色：

   $ oc adm policy add-role-to-user <role> <user> -n <project>

   例如，您可以运行以下命令，将 admin 角色添加到 joe 项目中的 alice 用户：

   $ oc adm policy add-role-to-user admin alice -n joe

   提示

   您还可以应用以下 YAML 向用户添加角色：

   apiVersion: rbac.authorization.k8s.io/v1
   kind: RoleBinding
   metadata:
     name: admin-0
     namespace: joe
   roleRef:
     apiGroup: rbac.authorization.k8s.io
     kind: ClusterRole
     name: admin
   subjects:
   - apiGroup: rbac.authorization.k8s.io
     kind: User
     name: alice

2. 查看本地角色绑定，并在输出中验证添加情况：

   $ oc describe rolebinding.rbac -n <project>

   例如，查看 joe 项目的本地角色绑定：

   $ oc describe rolebinding.rbac -n joe

   输出示例
