docker-无法在etcd3中找到Kubernetes apiserver的数据

我正在使用kargo中的ansible脚本来构建集群.尽管查看了apiserver的详细日志,但我无法找到将数据存储在etcd3中的位置.

这是我看到的hyperkube apiserver日志：

$docker logs k8s_kube-apiserver.fd19548d_kube-apiserver-kube-master-01_kube-system_2f6ad6b0bf81ca6a0e2b4d499a25fc89_aa25196e

hyperkube apiserver使用以下参数启动：

$docker inspect k8s_kube-apiserver.b6395694_kube-apiserver-kube-master-01_kube-system_2f6ad6b0bf81ca6a0e2b4d499a25fc89_4338b366

        ],

没有,它在哪里覆盖/ registry的默认etcd前缀.我不知道apiserver在哪里存储数据.

$docker exec -it etcd3 etcdctl --peers https://10.60.68.11:2379 ls /registry
Error:  100: Key not found (/registry) [163]

最佳答案

通过kubernetes获取存储在etcd v3中的键和值：

ETCDCTL_API=3 etcdctl --endpoints=http://localhost:2379 get --prefix /registry

要从etcd v3获取1个指定的键和值,例如：

ETCDCTL_API=3 etcdctl --endpoints=http://localhost:2379 get /registry/services/specs/default/kubernetes

根据：https://github.com/coreos/etcd/blob/master/Documentation/dev-guide/interacting_v3.md
