AMD Radeon Cloud SSH Connection Refused 的原因与解决方案
一、问题现象及分析
在AMD Radeon Cloud中自定义创建template时，即使勾选了SSH Access，大部分image也不会启动(甚至安装)sshd，导致通过AMD提供的 host:port 进行连接时，会报错Connection refused
官方文档中提到：
SSH connection does not appear
To expose SSH for a container, the application must:
- Run the SSH daemon inside the container.
- Configure a port namedSSHwith value 22.
The workload may need to pull the image, so the SSH port can appear after a delay.
推测大部分image还未更新SSH Access情况下的基础环境配置，故需在创建image后手动安装并启动sshd。
二、解决方案
根据上述分析，我们只需要在template创建好后，以notebook方式launch为实例，在JupyterLab中通过终端安装openssh-server并启动即可
注：因可能需要apt update，所以可以提前配置好apt的镜像以加快速度。另外，最终会有ss命令检查监听端口，可以提前安装iproute2或不执行此步。

该解决方案已上传github，可下载.sh文件或本地创建start_ssh.sh文件使用
wget https://raw.githubusercontent.com/Javrou/ARC-SSH-fix/main/start_ssh.sh chmod +x start_ssh.sh ./start_ssh.sh运行后尝试ssh连接：
