一直有这个冲动，想知道kubernetes往etcd里放了哪些数据，是如何组织的。能看到，才有把握知道它的实现和细节。找了很多文档，终于找到靠谱的。 =========================== https://www.jianshu.com/p/f9f83dd21770 =========================== 我是使用kubeadm工具安装的集群，要解除集群的资源占用要先把一些容器停掉，把kube-apiserver的编排文件从/etc/kubernetes/manifests/目录下先移出来，kubelet检查到会停止相应的pods,没有了kube-apiserver集群不会再创建新的pods,这时kubectl不可用了，使用docker命令把spinnaker项目的容器都删掉系统资源就能空闲出来。这时etcd还是正常的，用docker工具直接进入etcd。操作etcd有命令行工具 etcdctl，有两个api版本互不兼容的，系统默认的v2版本，kubernetes集群使用的是v3版本，v2版本下是看不到v3版本的数据的，我也是找了些资料才了解这个情况。使用环境变量定义api版本 export ETCDCTL_API=3 etcd有目录结构类似linux文件系统，获取所有key看一看： etcdctl get / --prefix --keys-only 一看就可以大概理解kubenetes的数据结构了，查询命名空间下所有部署的数据： etcdctl get /registry/deployments/default --prefix --keys-only 把想删除的删掉，列如： etcdctl del /registry/deployments/default/elevated-dragonfly-spinn-front50 删除deployments，pods这可以了，稍微减少一些资源，让kube-apiserver可以正常工作即可，其它资源还可以使用kubectl工具删除删掉些资源后退出etcd把kube-apiserver的编排文件放回/etc/kubernetes/manifests目录，服务会再次启动，然后再清理重新部署。 ======================================= k8s 1.9.3放在etcd里的根数据结构如下： etcdctl get / --prefix --keys-only /registry/apiregistration.k8s.io/apiservices/v1. /registry/apiregistration.k8s.io/apiservices/v1.apps
