雨雀：使用Dockerfile构建nginx镜像 · 语雀 (yuque.com)
yaml文件用法：02 Docker三剑客之一-Dockerfile · 语雀 (yuque.com)
1.使用Dockerfile构建nginx镜像
[root@localhost ~]# mkdir nginx && cd nginx
[root@localhost nginx]# echo "hello docker" > index.html2.编写Dockerfile
[root@localhost nginx]# cat Dockerfile
ARG version=7
FROM centos:${version}
MAINTAINER HWJ
RUN mkdir /hwjvol
VOLUME ["vdata1","hwjvol"]
LABEL version="12" author=hwj description="This is hwj's nginx"
RUN yum install -y wget
RUN wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
RUN yum install -y nginx
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
ADD index.html /usr/share/nginx/html/index.html
EXPOSE 80 443
CMD ["/usr/sbin/nginx"]yaml文件用法：02 Docker三剑客之一-Dockerfile · 语雀 (yuque.com)
3.构建镜像
[root@localhost nginx]# docker build -t hwj_ng:12 -f /root/nginx/Dockerfile .Sending build context to Docker daemon 4.096kB
