安裝並定製 Nginx

1、查閱對應的官方文件，首先下載映象檔案：

[[email protected] local]$ sudo docker pull nginx
[sudo] password for spider: 
Sorry, try again.
[sudo] password for spider: 
Using default tag: latest
Trying to pull repository docker.io/library/nginx ... 
latest: Pulling from docker.io/library/nginx

Status: Downloaded newer image for docker.io/nginx:latest
 

2、定製 Nginx

1、從容器中拷貝一份預設配置

首先在自己的主機上建立目錄/etc/docker/nginx用於存放定製 nginx 的配置檔案：

[[email protected] ~]$ sudo mkdir -p /etc/docker/nginx

接著新執行一個容器，並從其中拷貝出nginx.conf:

[[email protected] ~]$ sudo docker run --name tmp-nginx -d nginx
bb807eb140b85570258f834043560b37c16a655821a120273d49cc9369e45067
[[email protected]
 
 ~]$ sudo docker cp tmp-nginx:/etc/nginx/nginx.conf /etc/docker/nginx/nginx.conf

將臨時建立的容器刪除：

[[email protected] ~]$ sudo docker rm -f tmp-nginx
[sudo] password for spider: 
tmp-nginx

2、使用定製的 nginx.conf 啟動容器

[[email protected] ~]$ sudo docker run --name mynginx -v /etc/docker/nginx/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx
607b0f8096011829dd4cdea89270a7707bea003fac08e7516559713fb838de1e
[
 
[email protected] ~]$ sudo docker ps
CONTAINER ID        IMAGE                COMMAND                  CREATED             STATUS              PORTS                              NAMES
607b0f809601        nginx                "nginx -g 'daemon ..."   12 seconds ago      Up 11 seconds       80/tcp                             mynginx

到這一步，就算定製完了，如果我們要修改Nginx 伺服器的配置，只需修改我們主機上的nginx.conf,然後重新啟動容器就可以了。
