写了个Dockerfile，如何让nginx的配置文件读取宿主机上的文件呢？

FROM centos

RUN yum install -y pcre-devel wget net-tools gcc zlib zlib-devel make openssl-devel

# 添加文件

ADD http://nginx.org/download/nginx-1.12.1.tar.gz

RUN tar -zxvf nginx-1.12.1.tar.gz .

RUN mkdir -p /usr/local/nginx

RUN cd nginx-1.12.1 && ./configure --prefix=/usr/local/nginx && make && make install

RUN rm -vf /usr/local/nginx/conf/nginx.conf

COPY ./nginx_conf /usr/local/nginx/conf/nginx.conf





# Expose ports

EXPOSE 80





CMD service nginx start
