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。

If no server is specified "https://index.docker.io/v1/" is the default.

-e, --email= Email

--help=false Print usage

-p, --password= Password

-u, --username= Username

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

If no server is specified "https://index.docker.io/v1/" is the default.

--help=false Print usage

-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
