kill

Usage: docker kill [OPTIONS] CONTAINER [CONTAINER...] Kill a running container --help=false Print usage -s, --signal=KILL Signal 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。

load

Usage: docker load [OPTIONS] Load an image from a tar archive or STDIN --help=false Print usage -i, --input= Read from a tar archive file, instead of STDIN

与下面的save命令相对应，将下面sava命令打包的镜像通过load命令导入。

登录到自己的Docker register，需有Docker Hub的注册账号，或者自行搭建的私有仓库。

logout

Usage: docker logout [OPTIONS] [SERVER] Log out from a Docker registry. If no server is specified "https://index.docker.io/v1/" is the default. --help=false Print usage

从Docker register退出登录。

logs

Fetch the logs of a container -f, --follow=false Follow log output --help=false Print usage --since= Show logs since timestamp -t, --timestamps=false Show timestamps --tail=all Number of lines to show from the end of the logs

  

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。

# 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：

# docker logs -f -t --tail=3 nextcloud 2018-08-15T01:51:23.500951699Z root@nextcloud:/# 2018-08-15T01:51:36.154541783Z root@nextcloud:/# exit 2018-08-15T01:51:36.154917668Z exit
