我正在开发与 Kubernetes 交互的工具。我有OpenShift设置，允许所有身份验证提供程序。我可以如预期的那样登录 Web 控制台。
我还能够设置服务帐户并将群集角色绑定分配给服务帐户用户。尽管如此，当我使用该服务帐户的令牌访问 REST API 时，我还是被禁止了。
以下是我尝试通过 OpenShift 命令设置角色绑定时发生的情况：
[root@host1 ~]# oadm policy add-cluster-role-to-user view em7 --namespace=default
[root@host1 ~]# oadm policy add-cluster-role-to-user cluster-admin em7 --namespace=default
[root@host1 ~]# oadm policy add-cluster-role-to-user cluster-reader em7 --namespace=default
[root@host1 ~]# oc get secrets | grep em7
em7-dockercfg-hnl6m kubernetes.io/dockercfg 1 18h
em7-token-g9ujh kubernetes.io/service-account-token 4 18h
em7-token-rgsbz kubernetes.io/service-account-token 4 18h
TOKEN=`oc describe secret em7-token-g9ujh | grep token: | awk '{ print $2 }'`
[root@host1 ~]# curl -kD - -H "Authorization: Bearer $TOKEN" https://localhost:8443/api/v1/pods
HTTP/1.1 403 Forbidden

},

}
我也可以尝试使用(Openshift Admin Token(中的yaml文件： # 创建服务帐户"NS-Reader" api版本： v1 种类：服务帐户 元数据： 名称： NS 读取器 命名空间：默认
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
# "namespace" omitted since ClusterRoles are not namespaced
name: global-reader
rules:
- apiGroups: [""]
# add other rescources you wish to read
resources: ["pods", "secrets"]
verbs: ["get", "watch", "list"]
---
# This cluster role binding allows service account "ns-reader" to read pods in all available namespace
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: read-ns
subjects:
- kind: ServiceAccount
name: ns-reader
namespace: default
roleRef:
kind: ClusterRole
name: global-reader
apiGroup: rbac.authorization.k8s.io
当我运行这个时，我收到以下错误：
[root@host1 ~]# kubectl create -f stack_overflow_49667238.yaml
error validating "stack_overflow_49667238.yaml": error validating data: API version "rbac.authorization.k8s.io/v1" isn't supported, only supports API versions ["federation/v1beta1" "v1" "authentication.k8s.io/v1beta1" "componentconfig/v1alpha1" "policy/v1alpha1" "rbac.authorization.k8s.io/v1alpha1" "apps/v1alpha1" "authorization.k8s.io/v1beta1" "autoscaling/v1" "extensions/v1beta1" "batch/v1" "batch/v2alpha1"]; if you choose to ignore these errors, turn validation off with --validate=false
我已经尝试了列表中的几个不同的 API 版本，但它们都以类似的方式失败。
oadm policy add-cluster-role-to-user view em7授予名为em7
的用户您需要向服务帐户授予权限，例如oadm policy add-cluster-role-to-user view system:serviceaccount:default:em7
