创建SSHD自定义镜像
1、下载一个centos基础镜像
[root@docker ~]# docker pull centos:72、创建一目录用于存放Dockerfile
[root@docker ~]# mkdir ssh
[root@docker ~]# cd ssh/3、创建Dockerfiel
[root@docker ssh]# vim Dockerfile
#基于创建的镜像
FROM centos:7
#说明信息
MAINTAINER This is ssh
#更新yum
RUN yum -y update
#安装ssh依赖包
RUN yum -y install openssh* net-tools lsof telnet passwd
#面交互给容器root账号设置密码
RUN echo '123456'| passwd --stdin root
#关闭sshPAM认证
RUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config
#创建秘钥对
RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
#关闭PAM认证
RUN sed -i '/^session\s\+required\s\+pam_loginuid.so/s/^/#/' /etc/pam.d/sshd
#创建一个目录用于存放ssh公钥并设置宿主、宿组、设置执行权限
RUN mkdir -p /root/.ssh && chown root.root /root && chmod 700 /root/.ssh
#开放端口号
EXPOSE 22
#设置启动容器运行的命令

1、在上面的sshd镜像继续操作
[root@docker ~]# docker pull centos:72、创建一目录用于存放Dockerfile
[root@docker ~]# mkdir systemctl
[root@docker ~]# cd systemctl/3、创建Dockerfiel
[root@docker systemctl]# vim Dockerfile
#基于创建的镜像(镜像名称选的是上面的sshd镜像可以自定义选择其他镜像)
FROM sshd:new
#定义一个环境变量值为docker
ENV container docker
#清除容器内部的systemd文件
