docker安装_进入容器修改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

### 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
