创建Dockerfile文件

FROM    centos
MAINTAINER      Jeffrey "xxx@xxx.com"

RUN     /bin/echo 'root:gogogogo' |chpasswd
RUN     useradd jeffrey
RUN     /bin/echo 'jeffrey:gogogogo' |chpasswd
RUN     /bin/echo -e "LANG=\"en_US.UTF-8\"" >/etc/default/local
EXPOSE  22
EXPOSE  80
CMD     /usr/sbin/sshd -D

通过docker build命令构建镜像

-t 指定要创建的目标镜像名

. Dockerfile文件所有目录，可以指定绝对路径

设置镜像标签

~ % docker tag 95bc35e95aa7 jeffrey/centos:dev
docker tag 镜像ID, 用户名称、镜像源名(repository name)和新的标签名(tag)

操作命令(全)命令(简)
容器的创建docker container run docker run
容器的列出(up)docker container lsdocker ps
容器的列出(up和exit)docker container ls -adocker ps -a
容器的停止docker container stop docker stop
容器的删除docker container rm docker rm

1.批量停止

$ docker container ps
$ docker container stop eba
$ docker container stop $(docker container ps -aq)
stop后面跟Container ID

2.批量删除

$ docker container rm $(docker container ps -aq)

3.系统清理

快速对系统进行清理，删除停止的容器，不用的image等
$ docker system prune -a -f

4.容器运行模式

attach模式

docker container run -p 80:80 nginx
该模式创建容器在前台执行，输入输出结果会反映到本地端，本地端的输入输出也会反映到容器，ctrl + c 会让容器停止执行

detach模式

docker container run -d -p 80:80 nginx
该模式创建容器在后台执行

5.连接shell

创建一个容器并进入交互式模式

~ docker container run -it busybox sh

在一个已经运行的容器里执行一个额外的command

docker container exec -it 33d sh

6.run运行过程

$ docker container run -d --publish 80:80 --name webhost nginx

在本地查找是否有nginx这个image镜像

去远程的image registry查找nginx镜像（默认的registry是Docker Hub)

下载最新版本的nginx镜像 （nginx:latest 默认)

基于nginx镜像来创建一个新的容器，并且准备运行

docker engine分配给这个容器一个虚拟IP地址

在宿主机上打开80端口并把容器的80端口转发到宿主机上

启动容器，运行指定的命令（这里是一个shell脚本去启动nginx）
