go - 库伯内斯 403 : Cannot patch pods in the namespace

Question

在尝试部署使用 go-micro 框架的 pod 时，我收到以下错误:

2018/12/27 23:04:51 K8s: request failed with code 403
2018/12/27 23:04:51 K8s: request failed with body:
2018/12/27 23:04:51 {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"pods \"user-5676b5696-jspp5\" is forbidden: User \"system:serviceaccount:default:default\" cannot patch pods in the namespace \"default\"","reason":"Forbidden","details":{"name":"user-5676b5696-jspp5","kind":"pods"},"code":403}
2018/12/27 23:04:51 K8s: error

似乎 go-micro 没有从 pod 中修补 pod 的必要权限。

Answer 1

通过创建启用正确权限的集群角色绑定(bind)解决了该问题

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: micro-rbac
subjects:
  - kind: ServiceAccount
    # Reference to upper's `metadata.name`
    name: default
    # Reference to upper's `metadata.namespace`
    namespace: default
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
