docker之构建nginx镜像

Dockerfile构建nginx

1.安装nginx的shell脚本

#!/bin/bash yum install -y gcc gcc-c++ make pcre pcre-devel zlib zlib-devel cd /usr/local/nginx-1.16.0 ./configure --prefix=/usr/local/nginx && make && make install

2.dockerfile

FROM centos:7

ADD nginx-1.16.0.tar.gz /usr/local

COPY nginx_install.sh /usr/local

RUN sh /usr/local/nginx_install.sh

EXPOSE 80

3.制作Nginx镜像：

docker build -t mycentos:nginx .

4.Nginx镜像启动注意 

在容器里nginx是以daemon方式启动，退出容器时，nginx程序也会随着停止： /usr/local/nginx/sbin/nginx 

使用前台方式永久运行：/usr/local/nginx/sbin/nginx -g "daemon off;"

5.检查验证：

docker run -itd -p 999:80 mycentos:nginx /usr/local/nginx/sbin/nginx -g "daemon off;"

FROM centos:7 ADD nginx-1.16.0.tar.gz /usr/local COPY nginx_install.sh /usr/local RUN sh /usr/local/nginx_install.sh EXPOSE 80
