在k8s中，所有的容器，工作负载，最终都是要运行到节点上的，以容器的方式运行
那么，如果要在节点上，查看该节点上运行的容器的pod的名字，pod的信息，该怎么查看？
方法非常的简单。
1、登录到任意的工作节点
2、查看容器的ID
4f5de6bafde3就是容器的ID
root@nccztsjb-node-19 ~]# docker ps | grep dev-ssc-ssc 4f5de6bafde3 reg.yyuap.io:81/yonbip/ssc-ssc "/usr/bin/dumb-init …" 7 weeks ago Up 7 weeks k8s_dev-ssc-ssc_dev-ssc-ssc-78b477b487-z77xz_c87e2267-1001-4c70-bb2a-ab41f3b81aa3_c69a75d3-e339-407c-aa60-424d664dd0da_0 72838c69746a reg.yyuap.io:81/kubernetes/pause:3.3 "/pause" 7 weeks ago Up 7 weeks k8s_POD_dev-ssc-ssc-78b477b487-z77xz_c87e2267-1001-4c70-bb2a-ab41f3b81aa3_c69a75d3-e339-407c-aa60-424d664dd0da_0 [root@nccztsjb-node-19 ~]#
3、查看容器的信息
因为该容器是由k8s调度的，kubelet运行的，所以会有一些K8S相关的信息
通过docker inspect 命令来查看
docker inspect --format='{{index .Config.Labels "io.kubernetes.pod.name"}}' 4f5de6bafde3
就可以看到容器的pod的名字
[root@nccztsjb-node-19 ~]# docker inspect --format='{{index .Config.Labels "io.kubernetes.pod.name"}}' 4f5de6bafde3
dev-ssc-ssc-78b477b487-z77xz
[root@nccztsjb-node-19 ~]#
当然，还可以看到更多的信息
[root@nccztsjb-node-19 ~]# docker inspect 4f5de6bafde3
