## README

#### 有很多坑，但是无法一一写明。用一天的时间生命，最后发现改不了：人生要去接受无奈，用再多的生命时间去解决这些问题就是找死
* centos:7镜像中，如果容器启动命令用了 /usr/sbin/init ，就不要有 docker-entrypoint.sh ，好像docker-entrypoint.sh会影响到 /usr/sbin/init 的运行
* docker run --privileged -it -d centos:7.6.1810 /usr/sbin/init  不加 -d 参数，容器启动就是死
```
##### 制作Dockerfile文件
tee Dockerfile <<-'EOF'
FROM centos:7.6.1810

ENV ROOT_PASSWORD root

RUN curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo ; \
    echo "export LC_ALL=en_US.UTF-8" >> /etc/profile ; \
    yum install -y openssh-server openssh-clients firewalld ; \
    ssh-keygen -A ; \
    echo "root:${ROOT_PASSWORD}" | chpasswd ; \
    sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config; \
    sed -i 's/#UseDNS yes/UseDNS no/g' /etc/ssh/sshd_config; \
    sed -i 's/#PermitRootLogin yes/PermitRootLogin yes/' /etc/ssh/sshd_config; \
    yum clean all

EXPOSE 22

CMD ["/usr/sbin/init"]
