Calico etcd没有名为calico的密钥

Question

我有一个带calico网络的2节点kubernetes集群。所有的pods都已启动并运行。

NAMESPACE     NAME                                       READY     STATUS    RESTARTS   AGE

kube-system   kube-scheduler-kube-master-01              1/1       Running   0          14d

我想使用etcdctl查询calico-etcd，但得到以下错误。

# etcdctl --debug --endpoints "http://10.142.137.11:6666" get calico
start to sync cluster using endpoints(http://10.142.137.11:6666)
cURL Command: curl -X GET http://10.142.137.11:6666/v2/members
got endpoints(http://10.142.137.11:6666) after sync
Cluster-Endpoints: http://10.142.137.11:6666
cURL Command: curl -X GET http://10.142.137.11:6666/v2/keys/calico?quorum=false&recursive=false&sorted=false
Error:  100: Key not found (/calico) [4]

关于我为什么会得到这个错误，有什么建议吗？

正如@JakubBujny提到的，应该设置ETCDCTL_API=3以获得适当的结果。
