2.2. 退出node 退出容器,容器会被自动删除。 # exitlogoutpod default/nsenter-9yqytp terminated(Error)pod"nsenter-9yqytp"deleted 3. 原理 容器是弱隔离,共享节点的内核,通过cgroup和namespace来实现进程级别的隔离。那么通过在特权容器里执行nsenter的命令,则可以通过登录特权容器来实现登录node的shell环境。
有时候可能会在生产环境中的k8s的node节点对docker文件daemon.json进行更改并且重启或者node节点出现其他故障,但是该node节点上有很多pod还在跑着,这时候就需要用到drain和uncordon两个命令drain:释放排空node上所有pod,并且不接收新的pod进程 uncordon:恢复node,恢复接收新的pod进程kubectl drain在对节点执行维护之前,可以...

Yes, you have to firstly check the node to which pod has been scheduled against that microservice. kubectl -n namespace get pods -o wide Once you get the node, try to setup an ssh connection with the node, this link can be used to do it. Then you can execute following command i...
$ kubectl get node 显示node节点的标签信息 $ kubectl get node --show-labels 查看pod详细信息,也就是可以查看pod具体运行在哪个节点上(ip地址信息) $ kubectl get pod -o wide 查看服务的详细信息,显示了服务名称,类型,集群ip,端口,时间等信息
