我在练习 Security 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
required 中创建删除获取部署、状态集、守护程序集。
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“否”
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服务帐户,在命名空间中创建集群角色绑定,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。
