-H, --host list Daemon socket(s) to connect to (default [])
-l, --log-level string Set the logging level (“debug”, “info”, “warn”, “error”, “fatal”) (default “info”)
–tls Use TLS; implied by --tlsverify
–tlscacert string Trust certs signed only by this CA (default “/root/.docker/ca.pem”)
–tlscert string Path to TLS certificate file (default “/root/.docker/cert.pem”)
–tlskey string Path to TLS key file (default “/root/.docker/key.pem”)
–tlsverify Use TLS and verify the remote
-v, --version Print version information and quit

Management Commands:

container Manage containers

commit Create a new image from a container’s changes
cp Copy files/folders between a container and the local filesystem
create Create a new container
diff Inspect changes on a container’s filesystem
events Get real time events from the server
exec Run a command in a running container
export Export a container’s filesystem as a tar archive
history Show the history of an image
images List images
import Import the contents from a tarball to create a filesystem image
info Display system-wide information
inspect Return low-level information on Docker objects
kill Kill one or more running containers
load Load an image from a tar archive or STDIN
login Log in to a Docker registry
logout Log out from a Docker registry
logs Fetch the logs of a container
pause Pause all processes within one or more containers
port List port mappings or a specific mapping for the container
ps List containers
pull Pull an image or a repository from a registry

rm Remove one or more containers
rmi Remove one or more images
run Run a command in a new container
save Save one or more images to a tar archive (streamed to STDOUT by default)

1、docker start/stop/restart/kill

启动/停止/重启/杀掉容器

实例操作如下:

[root ~]# docker start myweb

[root ~]# docker stop myweb
[root ~]# docker restart myweb
[root ~]# docker kill -s kill myweb
参数 -s #向容器发送信号

这些命令不做过多解释

2、docker run

创建并启动一个新的容器

常用参数如下:

-d #后台运行容器,并返回容器ID -i #以交互式模式运行容器,常与-t参数同时使用 -t #给容器重新分配一个伪终端,常与-i参数同时使用 --name #给容器指定一个名称 -m #指定容器使用内存的最大值 --net #指定容器使用的网络类型 --link #链接到另一个容器 实例操作如下:

[root ~]# docker run -d --name nginx nginx:latest

#后台启动并运行一个名为nginx的容器,运行前它会自动去docker镜像站点下载最新的镜像文件
[root@docker ~]# docker run -d -P 80:80 nginx:latest
#后台启动并运名为nginx的容器,然后将容器的80端口映射到物理机的80端口
[root@docker ~]# docker run -d -v /docker/data:/docker/data -P 80:80 nginx:latest
#后台启动并运名为nginx的容器,然后将容器的80端口映射到物理机的80端口,并且将物理机的/docker/data目录映射到容器的/docker/data
[root@docker ~]# docker run -it nginx:latest /bin/bash
#以交互式模式运行容器,然后在容器内执行/bin/bash命令

3、docker rm

删除容器

常用参数如下:

-f #强制删除一个运行中的容器 -l #删除指定的链接 -v #删除与容器关联和卷 实例操作如下:

[root@docker ~]# docker rm -f mydocker

#强制删除容器
