Question

当我尝试执行此操作时：

oc create -f custom_clusterPolicyBinding.yml
Error from server: error when creating "custom_clusterPolicyBinding.yml": clusterpolicybindings ":default" already exists

oc version
oc v1.4.1
kubernetes v1.4.0+776c994
features: Basic-Auth GSSAPI Kerberos SPNEGO

这是custom_clusterPolicyBinding.yml

apiVersion: v1
kind: ClusterPolicyBinding
metadata:
  name: custom
policyRef:
  name: custom
roleBindings:
- name: custom:label-nodos
  roleBinding:
    groupNames:
    - pachi
    metadata:
      name: custom:label-nodos
    roleRef:
      name: custom:label-nodos
    subjects:
    - kind: Group
      name: pachi
    userNames: null

群集角色绑定自定义：label-nodos已存在

oc get clusterroleBinding | grep custom:label-nodos
custom:label-nodos                              /custom:label-nodos

群集角色绑定yaml的内容是：

apiVersion: v1
groupNames: null
kind: ClusterRoleBinding
metadata:
  name: custom:label-nodos
roleRef:
  name: custom:label-nodos
subjects: []
userNames: null

有什么想法吗？

不要直接编辑政策。只有一个群集策略和群集策略绑定。

相反，您可能希望创建一个内容与此类似的clusterrole（编辑它以授予您要发出的权限）：

apiVersion: v1
kind: ClusterRole
metadata:
  name: some-user
rules:
- apiGroups:
  - project.openshift.io
  - ""
  resources:
  - projects
  verbs:
  - list

和clusterrolebinding这样的内容（编辑它以绑定到正确的主题）：

apiVersion: v1
kind: ClusterRoleBinding
metadata:
  name: some-users
roleRef:
  name: some-user
subjects:
- kind: User
  name: foo

您还可以使用oadm policy add-*role-to-*命令来帮助绑定角色：

add-cluster-role-to-group
add-cluster-role-to-user
add-role-to-group
add-role-to-user

在openshift中上传带有集群策略绑定的yml时出错“已经存在”
