只读入口资源kubernetes用户

Question

我正试图授予命名空间中的默认服务帐户读取入口资源的能力。我希望能够读取集群的所有入口资源，这是否需要ClusterRole？这就是我一直在尝试的角色和绑定。kubectl命令CCD_ 1也返回"；否"；

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: my-namespace
name: my-ingress-reader
rules:
- apiGroups: ["", "networking.k8s.io", "networking", "extensions"] # "" indicates the core API group
resources: ["ingress"]
verbs: ["get", "watch", "list"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: my-ingress-reader
namespace: my-namespace
subjects:
- kind: ServiceAccount
name: default
namespace: my-namespace
roleRef:
kind: Role
name: my-ingress-reader
apiGroup: rbac.authorization.k8s.io

Answer 1

您的Role rules使用了不正确的api资源，即resources: ["ingress"]，它必须是resources: ["ingresses"]

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: my-namespace
name: my-ingress-reader
rules:
- apiGroups: ["", "networking.k8s.io", "networking", "extensions"] # "" indicates the core API group
resources: ["ingresses"]
verbs: ["get", "watch", "list"]

要检查正确的api资源，可以使用以下命令

root@controlplane:~# kubectl api-resources | grep -i ingress
ingresses                         ing          extensions/v1beta1                     true         Ingress
ingressclasses                                 networking.k8s.io/v1                   false        IngressClass
ingresses                         ing          networking.k8s.io/v1                   true         Ingress
