[root@b5926410fe60 /]# ssh-keygen -q -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ''
[root@b5926410fe60 /]# ssh-keygen -t dsa -f /etc/ssh/ssh_host_ed25519_key -N ''
然后，修改 /etc/ssh/sshd_config 配置信息：
UsePAM yes 改为 UsePAM no #centos7不改，改为no 会报不支持
UsePrivilegeSeparation sandbox 改为 UsePrivilegeSeparation no
[root@b5926410fe60 /]# sed -i "s/#UsePrivilegeSeparation.*/UsePrivilegeSeparation no/g" /etc/ssh/sshd_config
[root@b5926410fe60 /]# sed -i "s/UsePAM.*/UsePAM no/g" /etc/ssh/sshd_config
修改完后，重新启动sshd

#导出 export 与 保存 save 的区别
(1).export导出的镜像文件大小 小于 save保存的镜像
(2).export 导出（import导入）是根据容器拿到的镜像，再导入时会丢失镜像所有的历史，所以无法进行回滚操作（docker tag <LAYER ID> <IMAGE NAME>）；而save保存（load加载）的镜像，没有丢失镜像的历史，可以回滚到之前的层（layer）。（查看方式：docker images --tree）- 启动容器设置规定IP
