Question

我在练习安全 k8s 时手忙脚乱。这是我遇到的一个要解决的练习题。 问题： 创建 serviceaccount 'john' 并有权在给定的 namespace 'hr' Create clusterrole and clusterrolebindings 中创建 delete get 部署、statefulsets、daemonsets。

方法： 已尝试创建 sa 和 clusterrole 和 clusterrolebinding（将 clusterrole 与创建的 sa 绑定）但是当我检查它时给出了“不”

kubectl auth can-i create deploy --as john -n hr

no

创建 sa：

kubectl create sa john

创建集群角色：

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  # "namespace" omitted since ClusterRoles are not namespaced
  name: hrcrole
rules:
- apiGroups: ["apps"]
  #
  # at the HTTP level, the name of the resource for accessing Secret
  # objects is "secrets"
  resources: ["deployments", "statefulsets", "daemonsets"]
  verbs: ["get", "watch", "list", "delete"]

创建集群角色绑定：

apiVersion: rbac.authorization.k8s.io/v1
# This cluster role binding allows anyone in the "manager" group to read secrets in any namespace.
kind: ClusterRoleBinding
metadata:
  name: hrcrolebind
subjects:
- kind: User
  name: hruser # Name is case sensitive
  apiGroup: rbac.authorization.k8s.io
roleRef:
  kind: ClusterRole
  name: hrcrole
  apiGroup: rbac.authorization.k8s.io

我也尝试在命名空间中创建 serviceaccount，在命名空间中创建 clusterrolebinding 但我仍然没有。不幸的是，我没有解决这个问题的方法。感谢这里的任何帮助。

您正在尝试create部署：

kubectl auth can-i create deploy --as john -n hr

但是您不允许在集群角色中使用 create 动词：

verbs: ["get", "watch", "list", "delete"]

尝试像这样重新创建集群角色：

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  # "namespace" omitted since ClusterRoles are not namespaced
  name: hrcrole
rules:
- apiGroups: ["apps"]
  #
  # at the HTTP level, the name of the resource for accessing Secret
  # objects is "secrets"
  resources: ["deployments", "statefulsets", "daemonsets"]
  verbs: ["create", "get", "watch", "list", "delete"]

无法在具有服务帐户、已创建 ClusterRole 和 ClusterRolebinding 的命名空间中创建部署
