–help=false Print usage
-s, –signal=KILL Signal to send to the container
强制终止容器.
对于 stop 和 kill 的区别:
docker stop 命令给容器中的过程发送 SIGTERM 信号，默认行为是会导致容器退出，当然，容器内程序能够捕捉该信号并自行处理，例如能够抉择疏忽。而 dockerkill 则是给容器的过程发送 SIGKILL 信号，该信号将会使容器必然退出。

用于查看容器的日志，它将输出 (出) 到容器规范输出 (出) 的数据，作为日志输入到 docker logs 命令的终端上。罕用于后盾型容器。
87cb69be18bb 是一个数据流为输出、输入和谬误和容器，如下命令则会打印该容器的所有交互日志。
docker logs 87cb69be18bb
来个综合点的，查问容器最新的 3 条日志并打上工夫戳：
docker logs -f -t –tail=3 nextcloud
2018-08-15T01:51:23.500951699Z root@nextcloud:/#
