kill
  1. Usage:docker kill [OPTIONS] CONTAINER [CONTAINER...]Kill a running container --help=falsePrint usage -s, --signal=KILLSignal to send to the container




强制终止容器.
关于stop和kill的区别:
docker stop命令给容器中的进程发送SIGTERM信号，默认行为是会导致容器退出，当然，容器内程序可以捕获该信号并自行处理，例如可以选择忽略。而dockerkill则是给容器的进程发送SIGKILL信号，该信号将会使容器必然退出。

用于查看容器的日志，它将输入(出)到容器标准输入(出)的数据，作为日志输出到docker logs命令的终端上。常用于后台型容器。
87cb69be18bb是一个数据流为输入、输出和错误和容器，如下命令则会打印该容器的所有交互日志。
  1. # docker logs 87cb69be18bb




来个综合点的，查询容器最新的3条日志并打上时间戳：
  1. # docker logs -f -t --tail=3 nextcloud2018-08-15T01:51:23.500951699Z root@nextcloud:/#2018-08-15T01:51:36.154541783Z root@nextcloud:/# exit2018-08-15T01:51:36.154917668Z exit
