前言

1、docker安裝Nginx

1.1、觀察nginx是否可下載

healerjean$ docker search nginx

1.2、開始安裝

healerjean$ docker pull nginx

2、先執行這個nginx

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

3.1、檢視這個nginx的容器id號

docker ps

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

2、進入這個容器

2.1、docker exec ：在執行的容器中執行命令

        -d :分離模式: 在後臺執行
        -i :即使沒有附加也保持STDIN（標準輸入） 開啟,以互動模式執行容器，通常與 -t 同時使用；
        -t:
 
 為容器重新分配一個偽輸入終端，通常與 -i 同時使用；


docker exec -it 9fbe362214a6  /bin/bash 

docker exec -it 9fbe362214a6  /bin/bash 



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

3、docker cp

3.1、將容器29df10f32d44:/etc/nginx/nginx.conf 目錄拷貝到主機/Users/healerjean/Desktop目錄下

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

3.2、將主機/Users/healerjean/Desktop/AAA.md 拷貝到容器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
root@29df10f32d44:/# cd /etc/nginx/

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

4、 -v 掛在本地目錄到容器中

4.1、建議啟動的時候掛載 ：:ro 表示分配給只讀許可權（這樣容器就可以使用宿主主機的目錄了）

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
