Docker容器中部署靜態網頁
阿新 • • 發佈:2018-12-31
一般我們在訪問容器時需要通過容器的埠來訪問,那如何設定容器的埠對映呢?我們通過以下命令來設定:
docker run -p ip:hostPort:containerPort [--name] [-i] [-t] 映象名 [COMMAND][ARG...]
ip:表示宿主機ip
hostPort:宿主機埠號
containerPort:容器埠號
設定的方式有以下幾種:
- containerPort,指定容器埠號,宿主機埠隨機生成
[root@localhost ~]# docker run -p 80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash
- hostPort:containerPort對映主機埠和容器埠
[root@localhost ~]# docker run -p 8080:80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash
- ip::containerPort設定主機的隨機埠到容器埠
[root@localhost ~]# docker run -p 0.0.0.0::80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash
- ip:hostPort:containerPort對映指定地址的指定埠到容器的指定埠
[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
下面通過nginx在容器部署靜態網頁,通過以下步驟
- 建立80對映埠的互動式容器
- 安裝nginx
- 安裝文字編輯器vim
- 建立靜態網頁
- 執行nginx
- 驗證網頁
示例如下(如果安裝完ubuntu後不能安裝nginx進行apt-get update):
[[email protected] ~]# docker run -p 80 --name static_test -i -t hub.c.163.com/library/ubuntu /bin/bash

然後安裝vim:

The following additional packages will be installed:

然後建立存放靜態檔案的目錄,並建立一個簡單的html檔案:
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#
找到nginx的安裝目錄,更改default的root值為剛才建立的目錄:
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
然後啟動nginx,檢視容器程序:
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#
然後按ctrl+p,ctrl+q退出互動式容器。
使用docker ps
檢視容器的埠和執行情況,也可以通過dcoker port 映象名
檢視:
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 ~]#
可以看到容器的80埠對映到註解的32772埠。
通過curl訪問建立的index.html檔案:
[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 ~]#
也可以通過docker inspect 容器名
來檢視容器的詳細資訊和ip
通過容器ip進行訪問:
[root@localhost ~]# docker inspect static_test
其他資訊省略
"IPAddress": "172.17.0.5",
[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 ~]#
當我們使用docker stop 容器名
停止這個容器後,再使用docker start 容器名
啟動容器後,裡面的nginx並沒有啟動。那麼我們使用docker exec 容器名 nginx
來啟動:
[root@localhost ~]# docker stop static_test
static_test
[root@localhost ~]# docker ps
