CentOS7 Docker Nginx部署及運行實例分析

1、資源準備

dockerfile檔案

run yum -y update; yum clean all 
run yum -y install epel-release tar ; yum clean all 
run yum -y install nginx ; yum clean all 
add nginx.conf /opt/deploy/nginx/nginx.conf 
run echo "daemon off;" >> /opt/deploy/nginx/nginx.conf 
#run curl https://git.centos.org/sources/httpd/c7/acf5cccf4afaecf3afeb18c50ae59fd5c6504910 \ 
#  | tar -xz -c /usr/local/nginx/html \ 
#  --strip-components=1 
#run sed -i -e &#39;s/apache/nginx/g&#39; -e &#39;/apache_pb.gif/d&#39; \  
#  /usr/local/nginx/html/index.html 
 
expose 80 
 
#cmd [ "/usr/local/nginx/sbin" ]

注意：路徑需要在系統上面存在以及對應

nginx.conf檔案

2、執行建置鏡像指令

##複製程式碼 程式碼如下:

[root@localhost nginx]# sudo docker build --rm --tag os7/nginx:centos7 . 

執行結果截圖：

# 3.檢視映像是否安裝建置成功docker images

4、建立容器docker run -i -t -d -p 192.168.32.129:81:80 os7/nginx / bin/bash

注意：192.168.32.129這個ip的話，則需要在/etc/hosts中加入

192.168.32.129     lohosthost

#5、查看容器是否建立成功並啟動docker ps

6、測試是否成功存取curl http://192.168.32.129:81

會出現這個拒絕連接，那該怎麼辦呢？有辦法解決的，我們先進入該容器裡面

7、進入容器docker exec -i -t small_hodgkin /bin/sh

8、接著在容器裡面執行（直接輸入即可）

nginx

9、在容器外執行curl http://192.168.32.129:81

成功了。

10、再到虛擬機器外面透過瀏覽器存取
