倒计时， 默认用 4小时

# docker run -d -p 80:80 nginx

开启服务
-d 后台运行
-p 80:80 端口映射 宿主端口：docker端口

# docker exec -it 0915862262a94b78ff26d27eae5c3650ca6e4c5864b218894bea2adad37d7cb5 bash

进入容器

or docker exec -it 091586226 bash

-i即使没有附加也保持STDIN 打开 - 《什么是标准输入，标准输出(stdin,stdout)？》
（即保持可输入）

-t分配一个伪终端

# docker rm -f 0915862262a94b7

删除容器
-f force 强制删除

# docker commit 09 m1

提交容器，名字 m1

# Dockerfile

FROM nginx
ADD ./ /user/share/nginx/html/

基于 nginx
复制当前目录（./）到 nginx 目录（/user/share/nginx/html/）

# docker bulid -t m2 .

--tag, -t : 镜像的名字及标签，通常 name:tag 或者 name 格式；可以在一次构建中为一个镜像设置多个标签。

使用当前目录下 Dockerfile 创建镜像 ， 标签为 m2

# docker save m2 > 1.tar

将容器（m2）保存到一个文件（1.tar）里

# docker rmi m2

删除镜像

# docker load < 1.tar

加载 文件（1.tar） 为镜像

2 组织一个多容器项目docker-compose

  • 开启 docker 会“生成”一个 docker0 网卡

  • 容器和docker0网卡处于同一网段

  • 宿主机访问容器要通过<mark>网卡进行转发，路由过去</mark>

# docker run -dit alpine

alpine 最小的linux 系统 只有 5M 大小
-d 后台运行
-it 阻塞运行

# docker exec -it b49 sh

sh 工具 的形式 打开 alpine

# docker run -d -p8881:80 --name myng nginx

后台开启 nginx 别名 myng
docker端口号 80 映射到 宿主机 端口号 8881

# docker run -dit --link myng:myngnix alpine

后台阻塞开启 alpine
link 别名 myngnix 作为 myng服务的域名
