1、首先来个官方centos7的dockerfile，可建立最基础的centos7镜像放到自己harbor上（73M）
FROM centos:7
ENV container docker
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == \
systemd-tmpfiles-setup.service ] || rm -f $i; done); \
rm -f /lib/systemd/system/multi-user.target.wants/*;\
rm -f /etc/systemd/system/*.wants/*;\
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*;\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
CMD ["/usr/sbin/init"]
2、根据以上镜像建立其它环境 nginx(1.20.1)+php(7.4)? (515M)
FROM registry.yoyi.tv/yoyi/centos7:latest
ENV TZ=Asia/Shanghai
ENV LANG=en_US.UTF-8
COPY CentOS-Base.repo epel-7.repo yoyi.repo /etc/yum.repos.d/

groupadd www && useradd -g www -s /sbin/nologin www && \

yum clean all && rm -rf /var/cache/yum/*
COPY supervisord.conf /etc/supervisor/supervisord.conf
COPY supervisord.conf /etc/supervisord.conf
COPY nginx.conf /etc/nginx/nginx.conf
COPY php-fpm.conf /etc/php-fpm.conf
COPY www.yoyi.com.cn.conf /etc/nginx/vhost/
VOLUME /home/

ENTRYPOINT ["/usr/bin/supervisord", "-n", "-c", "/etc/supervisor/supervisord.conf"]
