# 作者信息
WORKDIR /usr/local/src/ #工作目录
ENV NG_VERSION nginx-1.16.1 #定义环境变量

RUN yum -y install epel-release #安装epel仓库
RUN yum -y install wget && wget http://nginx.org/download/$NG_VERSION.tar.gz && tar xzvf $NG_VERSION.tar.gz #下载nginx文件并解压

#安装编译依赖包
RUN yum install -y gcc gcc-c++ glibc make autoconf openssl openssl-devel && yum install -y pcre-devel libxslt-devel gd-devel GeoIP GeoIP-devel GeoIP-data
RUN yum clean all #清理仓库
RUN useradd -M -s /sbin/nologin nginx #创建nginx用户
WORKDIR /usr/local/src/$NG_VERSION #切换工作目录

#编译安装nginx
RUN ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-file-aio --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --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_stub_status_module && make && make install

ADD index.html /usr/local/nginx/html #复制测试页面到容器中
VOLUME /usr/local/nginx/html #设置容器中要挂在到宿主机的目录
ENV PATH /usr/local/nginx/sbin:$PATH #设置sbin环境变量

EXPOSE 80/tcp

#暴露80端口
ENTRYPOINT ["nginx"]
CMD ["-g","daemon off;"]
#当ENTRYPOINT和CMD连用时，CMD的命令是ENTRYPOINT命令的参数，两者连用相当于nginx -g "daemon off;"而当一起连用的时候命令格式最好一致（这里选择的都是
json格式的是成功的，如果都是sh模式可以试一下）

事实证明，在语句后面直接跟“#”号写注释，docker build会运行报错的。

注释需要另起一行，“#”后加空格再写注释

docker build . -t registry/centos8:nginx-1.16.1

docker  build  -f  Dockerfile的名字   仓库名  -t  仓库名：端口/镜像名：标签

docker push 127.0.0.1:5000/nginx:v3

搭建私有镜像仓库，类似私有yum仓库源

client端

vim /etc/docker/daemon.json

{
"insecure-registries": [
"192.168.3.110:5000"
],
"registry-mirrors": ["https://v16stybc.mirror.aliyuncs.com"]
