摘要：在Docker容器中部署静态网页的方法教程
<span style="color: #ff0000">[b]前言[/b]</span>
一般我们在访问容器时需要通过容器的端口来访问，那如何设置容器的端口映射呢？
<span style="color: #ff0000">[b]我们通过以下命令来设置：[/b]</span>
<div class="sucaicode">
<pre class="brush:bash;">
docker run -p ip:hostPort:containerPort [--name] [-i] [-t] 镜像名 [COMMAND][ARG...]</pre>
</div>
[list]
[*]ip：表示宿主机ip[/*]
[*]hostPort：宿主机端口号[/*]
[*]containerPort：容器端口号[/*]
[/list]
<span style="color: #ff0000">[b]设置的方式有以下几种：[/b]</span>
containerPort，指定容器端口号,宿主机端口随机生成
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker run -p 80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash</pre>
</div>
hostPort：containerPort映射主机端口和容器端口
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker run -p 8080:80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash</pre>
</div>
ip::containerPort设置主机的随机端口到容器端口
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker run -p 0.0.0.0::80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash</pre>
</div>
ip:hostPort:containerPort映射指定地址的指定端口到容器的指定端口
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker run -p 0.0.0.0:8080:80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash</pre>
</div>
[b]下面通过nginx在容器部署静态网页，通过以下步骤 [/b]
- 创建80映射端口的交互式容器
- 安装nginx
- 安装文本编辑器vim
- 创建静态网页
- 运行nginx
- 验证网页
示例如下（如果安装完ubuntu后不能安装nginx进行[code]apt-get update[/code]）:
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker run -p 80 --name static_test -i -t hub.c.163.com/library/ubuntu /bin/bash
root@25fcbf6e953d:/# apt-get install -y nginx

</div>
然后安装vim:
<div class="sucaicode">
<pre class="brush:bash;">
root@25fcbf6e953d:/# apt-get install -y vim
Reading package lists... Done

The following additional packages will be installed:
**安装日志省略。。。。。。。。。。**</pre>
</div>
然后建立存放静态文件的目录，并创建一个简单的html文件：
<div class="sucaicode">
<pre class="brush:bash;">
root@25fcbf6e953d:/# mkdir -p /var/www/html
root@25fcbf6e953d:/#
root@25fcbf6e953d:/# cd /var/www/html/
root@25fcbf6e953d:/var/www/html# vim index.html
root@25fcbf6e953d:/var/www/html# ll
total 8
drwxr-xr-x. 2 root root 53 Mar 13 05:02 ./
drwxr-xr-x. 3 root root 17 Mar 13 04:50 ../
-rw-r--r--. 1 root root 79 Mar 13 05:02 index.html
-rw-r--r--. 1 root root 612 Mar 13 04:51 index.nginx-debian.html
root@25fcbf6e953d:/var/www/html# cat index.html
<html>
<body>
<h1>
this is the first docker static file
</h1>
</body>
</html>
root@25fcbf6e953d:/var/www/html# </pre>
</div>
找到nginx的安装目录，更改default的root值为刚才创建的目录：
<div class="sucaicode">
<pre class="brush:bash;">
root@25fcbf6e953d:/var/www/html# whereis nginx
nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx
root@25fcbf6e953d:/var/www/html# cd /etc/nginx/sites-enabled/
root@25fcbf6e953d:/etc/nginx/sites-enabled# ll
total 4
drwxr-xr-x. 2 root root 20 Mar 13 04:51 ./
drwxr-xr-x. 6 root root 4096 Mar 13 04:51 ../
lrwxrwxrwx. 1 root root 34 Mar 13 04:51 default -> /etc/nginx/sites-available/default
root@25fcbf6e953d:/etc/nginx/sites-enabled# vim default </pre>
</div>
[img]http://img.1sucai.cn/uploads/article/2018010710/20180107100156_0_81370.png[/img]
然后启动nginx,查看容器进程：
<div class="sucaicode">
<pre class="brush:bash;">
root@25fcbf6e953d:/etc/nginx/sites-enabled# nginx
root@25fcbf6e953d:/etc/nginx/sites-enabled# ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 04:48 ? 00:00:00 /bin/bash
root 827 1 0 05:06 ? 00:00:00 nginx: master process nginx
www-data 828 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 829 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 830 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 831 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 832 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 833 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 834 827 0 05:06 ? 00:00:00 nginx: worker process
www-data 835 827 0 05:06 ? 00:00:00 nginx: worker process
root 836 1 0 05:07 ? 00:00:00 ps -ef
root@25fcbf6e953d:/etc/nginx/sites-enabled# </pre>
</div>
然后按ctrl+p,ctrl+q退出交互式容器。
使用[code]Docker ps[/code]查看容器的端口和运行情况，也可以通过[code]dcoker port [/code]镜像名查看：
<div class="sucaicode">
<pre class="brush:bash;">
root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
25fcbf6e953d hub.c.163.com/library/ubuntu "/bin/bash" 18 minutes ago Up 18 minutes 0.0.0.0:32772->80/tcp static_test
[root@localhost ~]# docker port static_test
80/tcp -> 0.0.0.0:32772
[root@localhost ~]# </pre>
</div>
可以看到容器的80端口映射到注解的32772端口。
通过curl访问创建的index.html文件：
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# curl http://127.0.0.1:32772/index.html
<html>
<body>
<h1>
this is the first docker static file
</h1>
</body>
</html>
[root@localhost ~]#</pre>
</div>
也可以通过[code]docker inspect [/code]容器名来查看容器的详细信息和ip
通过容器ip进行访问：
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker inspect static_test
其他信息省略
"IPAddress": "172.17.0.5",</pre>
</div>
<div class="sucaicode">
<pre class="brush:plain;">
[root@localhost ~]# curl http://172.17.0.5/index.html
<html>
<body>
<h1>
this is the first docker static file
</h1>
</body>
</html>
[root@localhost ~]# </pre>
</div>
当我们使用[code]docker stop[/code] 容器名停止这个容器后，再使用[code]docker start [/code]容器名启动容器后，里面的nginx并没有启动。那么我们使用[code]docker exec [/code]容器名 nginx来启动：
<div class="sucaicode">
<pre class="brush:bash;">
[root@localhost ~]# docker stop static_test
static_test
[root@localhost ~]# docker ps
