我的错误日志

Question

我正在使用kubernetes本地

虽然我使用kubernetes构建gitlab有一些问题。我认为这与serviceaccount或角色绑定有关。但找不到正确的方法

我找到了这些帖子

Kubernetes log, User "system:serviceaccount:default:default" cannot get services in the namespace

问题是由于您的默认服务帐户无权获取群集范围内的节点或Pod。要解决的最小群集角色和群集角色绑定是：

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRole
metadata:
  name: prom-admin
rules:
# Just an example, feel free to change it
- apiGroups: [""]
  resources: ["pods", "nodes"]
  verbs: ["get", "watch", "list"]

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

上述群集角色为默认服务帐户提供访问任何名称空间中任何Pod或节点的权限。

您可以更改群集角色以提供对服务帐户的更多权限，如果您想授予对默认服务帐户的所有访问权限，则替换resources: ["*"]中的prom-admin

希望这会有所帮助。

禁止使用kubernetes pods / nodes
