k8s namespace权限问题无法读取configmap

报错信息：

Message: Forbidden!Configured service account doesn't have access. Service account may have been revoked. User "system:serviceaccount:mycomp-services-process:default" cannot get resource “pods” in API group "" in the namespace "sscp-sit"

报错截图：

解决方法：

在第一个错误中，问题是默认命名空间中的serviceaccount default无法获取服务，因为它无法访问list / get服务。 因此，您需要做的是使用clusterrolebinding为该用户分配角色。

遵循一组最低权限，您可以先创建一个可以访问列表服务的角色：

kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: sscp-sit-minimal
  namespace: sscp-sit
rules:
- apiGroups:
  - ""
  - "extensions"
  resources:
  - nodes
  - services
  - endpoints
  - namespaces
  - ingresses
  - secrets
  - pods
  verbs:
  - get
  - list
  - watch
- apiGroups:
  - ""
  - "extensions"
  resources:
  - configmaps
  - events
  - ingresses/status
  verbs:
  - get
  - list
  - watch
  - update
  - create
  - patch
