在Docker容器中部署靜態(tài)網(wǎng)頁(yè)的方法教程
前言
一般我們?cè)谠L(fǎng)問(wèn)容器時(shí)需要通過(guò)容器的端口來(lái)訪(fǎng)問(wèn),那如何設(shè)置容器的端口映射呢?
我們通過(guò)以下命令來(lái)設(shè)置:
docker run -p ip:hostPort:containerPort [--name] [-i] [-t] 鏡像名 [COMMAND][ARG...]
- ip:表示宿主機(jī)ip
- hostPort:宿主機(jī)端口號(hào)
- containerPort:容器端口號(hào)
設(shè)置的方式有以下幾種:
containerPort,指定容器端口號(hào),宿主機(jī)端口隨機(jī)生成
[root@localhost ~]# docker run -p 80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash
hostPort:containerPort映射主機(jī)端口和容器端口
[root@localhost ~]# docker run -p 8080:80 --name web_test -i -t 80864d42dd23 hub.c.163.com/library/ubuntu /bin/bash
ip::containerPort設(shè)置主機(jī)的隨機(jī)端口到容器端口
[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映射指定地址的指定端口到容器的指定端口
[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(guò)nginx在容器部署靜態(tài)網(wǎng)頁(yè),通過(guò)以下步驟
- 創(chuàng)建80映射端口的交互式容器
- 安裝nginx
- 安裝文本編輯器vim
- 創(chuàng)建靜態(tài)網(wǎng)頁(yè)
- 運(yùn)行nginx
- 驗(yàn)證網(wǎng)頁(yè)
示例如下(如果安裝完ubuntu后不能安裝nginx進(jìn)行apt-get update):
[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 Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package nginx root@25fcbf6e953d:/# apt-get update Get:1 http://archive.ubuntu.com/ubuntu xenial InRelease [247 kB] Get:2 http://archive.ubuntu.com/ubuntu xenial-updates InRelease [102 kB] **中間日志省略。。。。。。。。。。** Fetched 24.9 MB in 9s (2717 kB/s) Reading package lists... Done root@25fcbf6e953d:/# apt-get install -y nginx Reading package lists... Done Building dependency tree Reading state information... Done **安裝日志省略。。。。。。。。。。**
然后安裝vim:
root@25fcbf6e953d:/# apt-get install -y vim Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: **安裝日志省略。。。。。。。。。。**
然后建立存放靜態(tài)文件的目錄,并創(chuàng)建一個(gè)簡(jiǎn)單的html文件:
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值為剛才創(chuàng)建的目錄:
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

然后啟動(dòng)nginx,查看容器進(jìn)程:
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#
然后按ctrl+p,ctrl+q退出交互式容器。
使用Docker ps查看容器的端口和運(yùn)行情況,也可以通過(guò)dcoker port 鏡像名查看:
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端口映射到注解的32772端口。
通過(guò)curl訪(fǎng)問(wèn)創(chuàng)建的index.html文件:
[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(guò)docker inspect 容器名來(lái)查看容器的詳細(xì)信息和ip
通過(guò)容器ip進(jìn)行訪(fǎng)問(wèn):
[root@localhost ~]# docker inspect static_test 其他信息省略 "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(dāng)我們使用docker stop 容器名停止這個(gè)容器后,再使用docker start 容器名啟動(dòng)容器后,里面的nginx并沒(méi)有啟動(dòng)。那么我們使用docker exec 容器名 nginx來(lái)啟動(dòng):
[root@localhost ~]# docker stop static_test static_test [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b4f32bbe4a34 hub.c.163.com/library/ubuntu "/bin/bash" 41 hours ago Up 41 hours loving_brattain d75a2d8c7822 xingguo/df_test1 "nginx -g 'daemon off" 2 days ago Up 2 days 0.0.0.0:32770->80/tcp df_nginx_web 959c0fc5d903 xingguo/commit_test1 "nginx -g 'daemon off" 2 days ago Up 2 days 0.0.0.0:32769->80/tcp nginx_test [root@localhost ~]# docker start static_test static_test [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 25fcbf6e953d hub.c.163.com/library/ubuntu "/bin/bash" 29 minutes ago Up 2 seconds 0.0.0.0:32773->80/tcp static_test b4f32bbe4a34 hub.c.163.com/library/ubuntu "/bin/bash" 41 hours ago Up 41 hours loving_brattain d75a2d8c7822 xingguo/df_test1 "nginx -g 'daemon off" 2 days ago Up 2 days 0.0.0.0:32770->80/tcp df_nginx_web 959c0fc5d903 xingguo/commit_test1 "nginx -g 'daemon off" 2 days ago Up 2 days 0.0.0.0:32769->80/tcp nginx_test [root@localhost ~]# docker top static_test UID PID PPID C STIME TTY TIME CMD root 4719 4702 0 13:17 pts/2 00:00:00 /bin/bash [root@localhost ~]# docker exec static_test nginx [root@localhost ~]# docker top static_test UID PID PPID C STIME TTY TIME CMD root 4719 4702 0 13:17 pts/2 00:00:00 /bin/bash root 4800 1 0 13:18 ? 00:00:00 nginx: master process nginx amandab+ 4801 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4802 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4803 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4804 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4805 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4806 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4807 4800 0 13:18 ? 00:00:00 nginx: worker process amandab+ 4808 4800 0 13:18 ? 00:00:00 nginx: worker process [root@localhost ~]#
