我在 gce 中有一个 mongo 数据库。（配置见下文）

当我将它部署到1.7.12-gke.1 时， 一切正常。这意味着 sidecar 然后解析 pod 和链接

现在，当我将相同的配置部署到1.8.7-gke.1时，会导致缺少列出 pod 的权限，请参见下文。

我不明白发生了什么变化。我假设我需要为用户帐户分配特定权限，对吗？

我错过了什么？

错误日志

根据原始解决方案：https ://github.com/cvallance/mongo-k8s-sidecar/issues/75

您必须创建将授予默认服务帐户查看权限的角色绑定：

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: default-view
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: view
subjects:
  - kind: ServiceAccount
    name: default
    namespace: default
