我要评论1.创建目录
[root@openeuler-node1 db]# mkdir sshd_ubuntu
2.创建 dockerfile、 run.sh 、authorized_keys、vim aliyun.list 文件
[root@openeuler-node1 sshd_ubuntu]# cd sshd_ubuntu [root@openeuler-node1 sshd_ubuntu]# touch dockerfile run.sh authorized_keys vim aliyun.list
3.在宿主主机上生成 ssh 密钥对,写入authorized_keys
[root@openeuler-node1 ~]# ssh-keygen -t rsa [root@openeuler-node1 sshd_ubuntu]# cd sshd_ubuntu [root@openeuler-node1 sshd_ubuntu]# cat ~/.ssh/id_rsa.pub > authorized_keys
4.编写更改ubuntu的源为国内aliyun源
[root@openeuler-node1 sshd_ubuntu]# vim aliyun.list deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
5.编写run.sh
#!/bin/bash /usr/sbin/sshd -d
5.编写 dockerfile
[root@openeuler-node1 sshd_ubuntu]# vim dockerfile
from ubuntu:18.04
maintainer yuj<yj@qq.com>
copy aliyun.list /etc/apt/sources.list.d/aliyun.list
run apt update && \
apt install -y openssh-server && \
mkdir /var/run/sshd && \
sed -ri 's/session required pam_loginuid.so/#session required pam_loginuid.so/g' /etc/pam.d/sshd && \
mkdir /root/.ssh
copy authorized_keys /root/.ssh/
copy run.sh /run.sh
run chmod 755 /run.sh
expose 22
cmd ["/run.sh"]
6.制作镜像并启动容器
[root@openeuler-node1 sshd_ubuntu]# docker build -t sshd:ubuntu_v1 ./ [root@openeuler-node1 sshd_ubuntu]# docker run -d -p sshd:ubuntu_v1
7.查看容器运行状态
[root@openeuler-node1 sshd_ubuntu]# docker ps container id image command created status ports names 3df76cc3dedd sshd:ubuntu_v1 "/run.sh" 6 seconds ago up 5 seconds 0.0.0.0:32776->22/tcp, :::32776->22/tcp vigorous_williamson
8.用ssh连接登陆这个容器
[root@openeuler-node1 sshd_ubuntu]# ssh 192.168.136.55 -p 32776 the authenticity of host '[192.168.136.55]:32776 ([192.168.136.55]:32776)' can't be established. ed25519 key fingerprint is sha256:pcuipopbts35izroq3pvzsu0+w+i7o1zhevc1xmdghu. this key is not known by any other names are you sure you want to continue connecting (yes/no/[fingerprint])? yes warning: permanently added '[192.168.136.55]:32776' (ed25519) to the list of known hosts. welcome to ubuntu 18.04.6 lts (gnu/linux 5.10.0-182.0.0.95.oe2203sp3.x86_64 x86_64) root@3df76cc3dedd:~#
