[TOC]

（1）以 openeuler:22.03-lts 为例，首先以交互的方式启动容器
```bash
docker run -it --rm --privileged openeuler/openeuler:22.03-lts /bin/bash
```

（2）然后安装基础软件即ssh服务
```bash
dnf install -y net-tools
dnf install -y openssh-clients
dnf install -y openssh-server
ssh-keygen -A
mkdir /var/run/sshd
echo 'root:osImagePassword123' |chpasswd
echo 'StrictHostKeyChecking no' >> /etc/ssh/ssh_config
echo 'UserKnownHostsFile /dev/null ' >> /etc/ssh/ssh_config
```

（3）然后启动sshd服务
```bash
/usr/sbin/sshd -D &
```

（4）然后将运行的容器生成镜像，这里 e4827a50c0ed 为容器id
```bash
docker commit 183d39a4b058  redrose2100/openeuler-ssh:22.03-lts
```

（5）此时查看镜像，如下镜像已经生成。
```bash
[root@centos7-1 ~]# docker images | grep redrose2100/openeuler
redrose2100/openeuler-ssh   22.03-lts   2dc9c7518bbc   About a minute ago   666MB
[root@centos7-1 ~]#
```

（6）将运行的容器退出，直接执行exit即可退出

（7）然后使用新生成的镜像启动容器
```bash
docker run -d --name=vm1 --privileged redrose2100/openeuler-ssh:22.03-lts /usr/sbin/sshd -D
```

（8）此时查看容器，可以看到容器已经在后台运行
```bash
[root@centos7-1 openeuler]# docker ps
CONTAINER ID   IMAGE                                 COMMAND               CREATED         STATUS         PORTS     NAMES
6f2f87e1b117   redrose2100/openeuler-ssh:22.03-lts   "/usr/sbin/sshd -D"   3 seconds ago   Up 2 seconds             vm1
[root@centos7-1 openeuler]#
```

（9）然后通过docker exec 的方式进入容器，查看ip地址
```bash
[root@centos7-1 openeuler]# docker exec -it 6f2f87e1b117 bash

（10）退出容器，然后通过ssh方式登录，如下可以登录
```bash
[root@centos7-1 openeuler]# ssh -o "StrictHostKeyChecking=no" root@172.17.0.2
