这里只是做一个简单的演示，基础镜像选用 CentOS 7，Nginx 选用 Nginx 的扩展版本 OpenResty 1.15.8.2。
Nginx 镜像 Dockerfile 脚本如下：
FROM centos:centos7 MAINTAINER Nginx Dockerfile Write by John.Wang RUN yum -y install epel-release && yum -y install wget gcc make pcre-devel zlib-devel openssl-devel libxml2-devel libxslt-devel luajit GeoIP-devel gd-devel libatomic_ops-devel luajit-devel perl-devel perl-ExtUtils-Embed RUN cd /tmp && wget https://openresty.org/download/openresty-1.15.8.2.tar.gz && tar zxmf openresty-1.15.8.2.tar.gz && cd openresty-1.15.8.2 && ./configure --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-stream=dynamic --with-stream_ssl_module --with-stream_realip_module --with-stream_geoip_module=dynamic --with-libatomic --with-pcre-jit --with-stream_ssl_preread_module && gmake && gmake install ENV PATH $PATH:/usr/local/nginx/sbin RUN ln -s /usr/local/openresty/nginx /usr/local/nginx RUN ln -sf /dev/stdout /usr/local/nginx/logs/access.log && ln -sf /dev/stderr /usr/local/nginx/logs/error.log EXPOSE 80 ENTRYPOINT ["nginx", "-g", "daemon off;"]
在 Dockerfile 文件的同一目录下，执行如下命令构建 Nginx 的 Dokcer 镜像。
docker build -t nginx:v1.0 .
