設置容器的端口映射html

經過run命令的兩個選項來實現這個功能nginx

run【-P】【-p】web

-P（大寫的P將爲容器暴露的全部端口進行映射）（隨機映射）docker

-P，--publish-all=true|false默認爲falseubuntu

dockerrun-P -i-tubuntu/bin/bashvim

-p(小寫的p可以指定映射容器哪些端口)bash

-p，--publish=[]curl

指定端口有四種狀況tcp

containerPort編輯器

docker run -p 80 -I -tubuntu /bin/bash

hostPort:containerPort

docker run -p8080:80 -I -t ubuntu /bin/bash

ip::containerPort

docker run -p0.0.0.0:80 -I -t ubuntu /bin/bash

ip:hostPort:containerPort

docker run -p0.0.0.0:8080:80 -I -t ubuntu /bin/bash

Nginx部署流程：

建立映射80端口的交互式容器

安裝Nginx

安裝文本編輯器vim

建立靜態頁面

修改Nginx配置文件

運行Nginx

驗證網站訪問

ubuntu@ubuntu-virtual-machine:~$docker run -p 80 --name web -i -t ubuntu /bin/bash

root@0cc8c10d217a:/# apt-get intsall -y nginx#安裝nginx

root@0cc8c10d217a:/var/www/html#apt-get install -y vim#安裝vim

root@0cc8c10d217a:/#mkdir -p /var/www/html

root@0cc8c10d217a:/# cd/var/www/html/

root@0cc8c10d217a:/var/www/html#

root@0cc8c10d217a:/var/www/html#cat index.html #編輯一個靜態頁面

<html>

<head>

<title>Nginx inDocker</title>

</head>

<body>

<h1>Hello,I'm website in Docker!</h1>

</body>

</html>

查看下nginx安裝在哪裏

root@0cc8c10d217a:/var/www/html#whereis nginx

nginx: /usr/sbin/nginx/etc/nginx /usr/share/nginx /usr/share/man/man1/nginx.1.gz

vim /etc/nginx/sites-enabled/default#打開default文件

將root的值改成咱們剛剛創建的靜態網站的位置

root@0cc8c10d217a:/var/www/html#cat /etc/nginx/sites-enabled/default|grep root

root /var/www/html;

# root /usr/share/nginx/html;

# deny access to .htaccess files, ifApache's document root

# root html;

root@0cc8c10d217a:/var/www/html#cd /

root@0cc8c10d217a:/#

root@0cc8c10d217a:~#ps -ef|grep nginx#查看進程

root 27163 13952 0 Apr22 ? 00:00:00 nginx: master process/usr/sbin/nginx

www-data 2716427163 0 Apr22 ? 00:00:05 nginx: worker process

www-data 2716727163 0 Apr22 ? 00:00:04 nginx: worker process

root 31545 31522 0 04:44 pts/0 00:00:00 grep --color=auto nginx

root@0cc8c10d217a:~#

能夠用ps和port查看端口映射的狀況

ubuntu@ubuntu-virtual-machine:~$docker ps

ubuntu@ubuntu-virtual-machine:~$ curl http://127.0.0.1:32769#訪問

也能夠用容器的ip地址來訪問

ubuntu@ubuntu-virtual-machine:~$docker inspect web|grep IPAddress

"IPAddress":"172.17.0.7",

ubuntu@ubuntu-virtual-machine:~$

ubuntu@ubuntu-virtual-machine:~$curl http://172.17.0.7

ubuntu@ubuntu-virtual-machine:~$ docker stop web#停掉容器

web

ubuntu@ubuntu-virtual-machine:~$

ubuntu@ubuntu-virtual-machine:~$ docker start -i web#啓動容器

root@0cc8c10d217a:/# ps -ef#從新啓動後並無開啓nginx

UID PID PPID C STIME TTY TIME CMD

root 1 0 16 17:17 ? 00:00:02/bin/bash

root 11 1 26 17:17 ? 00:00:00 ps-ef

先ctrl+pctrl+q推出，這個時候就能夠用exec命令來啓動nginx

ubuntu@ubuntu-virtual-machine:~$ docker exec web nginx#再次啓動nginx

ubuntu@ubuntu-virtual-machine:~$docker top web

UID PID PPID C STIME TTY TIME CMD

root 32349 7138 1 01:17 pts/0 00:00:02 /bin/bash

root 32396 32349 0 01:19 ? 00:00:00 nginx: master process nginx

www-data 32397 32396 0 01:19 ? 00:00:00 nginx: worker process

這時候再用原來的IP地址來訪問，就訪問失敗了

ubuntu@ubuntu-virtual-machine:~$curl http://172.17.0.7

curl: (7) Failed toconnect to 172.17.0.7 port 80: No route to host

ubuntu@ubuntu-virtual-machine:~$docker inspect web|grep -E "IPAddress|HostPort"

"HostPort":""

"IPAddress":"172.17.0.8",

"HostPort":"32770"

#發現容器的IP地址和端口已經改變了（當咱們從新開啓時會發生改變）
