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.
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。

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

与上面的 save 命令绝对应,将上面 sava 命令打包的镜像通过 load 命令导入。

login

Register or log in to a Docker registry.

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

登录到本人的 Docker register,需有 Docker Hub 的注册账号,或者自行搭建的公有仓库。

logout
Usage: docker logout [OPTIONS] [SERVER]

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:/#

2018-08-15T01:51:36.154541783Z root@nextcloud:/# exit
