以nginx为例：
#-----------dockerfile构建镜像--------
dockerfile包括:
1、基础镜像信息
2、维护者信息
3、镜像操作指令
4、容器启动时执行指令

dockerfile目录：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

#This is My first Dockerfile #Version 1.0 #Author: YangYangming   #Base images FROM centos   #MAINTAINER MAINTAINER YangYangming   #ADD ADD pcre-8.37.tar.gz /usr/local/src ADD nginx-1.17.5.tar.gz /usr/local/src   #RUN RUN yum install -y wget gcc gcc-c++ make openssl-devel RUN useradd -s /sbin/nologin -M www   #WORKDIR WORKDIR /usr/local/src/nginx-1.17.5   RUN ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_stub_status_module --with-pcre=/usr/local/src/pcre-8.37 && make && make install   RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf   ENV PATH /usr/local/nginx/sbin:$PATH   EXPOSE 80   CMD ["nginx"]
