1、docker安装Nginx

1.1、观察nginx是否可下载

healerjean$ docker search nginx

1.2、开始安装

healerjean$ docker pull nginx

2、先运行这个nginx

healerjean$ docker run -it -p 80:80 nginx

3.1、查看这个nginx的容器id号

docker ps

healerjean$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED                  STATUS              PORTS                NAMES
9fbe362214a6        nginx               "nginx -g 'daemon of…"   Less than a second ago   Up 2 seconds        0.0.0.0:80->80/tcp   objective_chandrasekhar
healerjean$

2、进入这个容器

2.1、docker exec ：在运行的容器中执行命令

		-d :分离模式: 在后台运行
		-i :即使没有附加也保持STDIN（标准输入） 打开,以交互模式运行容器，通常与 -t 同时使用；
		-t: 为容器重新分配一个伪输入终端，通常与 -i 同时使用；


docker exec -it 9fbe362214a6  /bin/bash 

docker exec -it 9fbe362214a6  /bin/bash 



healerjean$ docker exec -it 9fbe362214a6  /bin/bash

3、docker cp

3.1、将容器29df10f32d44:/etc/nginx/nginx.conf 目录拷贝到主机/Users/healerjean/Desktop目录下

:~ healerjean$  docker cp  29df10f32d44:/etc/nginx/nginx.conf /Users/healerjean/Desktop

3.2、将主机/Users/healerjean/Desktop/AAA.md 拷贝到容器29df10f32d44:/etc/nginx/中

 docker cp /Users/healerjean/Desktop/AAA.md 29df10f32d44:/etc/nginx/


:~ healerjean$ docker cp /Users/healerjean/Desktop/AAA.md 29df10f32d44:/etc/nginx/


:~ healerjean$ docker exec -it 29df10f32d44 /bin/bash

-rw-r--r-- 1 root root    3610 Jul 24 13:02 win-utf
root@29df10f32d44:/etc/nginx#

4、 -v 挂在本地目录到容器中

4.1、建议启动的时候挂载 ：:ro 表示分配给只读权限（这样容器就可以使用宿主主机的目录了）

docker run -p 80:80  -v /Users/healerjean/Desktop:/usr/local/mynginx:ro -d nginx

JeandeMBP:~ healerjean$ docker run -p 80:80 -it -v /Users/healerjean/Desktop:/usr/local/mynginx:ro -d nginx
