Ssh 远程shell命令作业无法解决Azure发布管道中的主机名问题

我有一个Azure发布管道，它使用Azure管道代理池（ubuntu-20.04）。我试图使用SSH部署任务在使用SSH密钥进行身份验证的远程服务器中执行远程shell命令。作为安全措施，只能通过“跳转服务器”访问远程服务器。我使用安装SSH密钥任务来安装相应的SSH密钥。尽管如此，我在installssh-Key任务中发现的一个限制是，我只能提供一个SSH-config条目，但我需要指定两个条目，并另外使用ProxyCommand指令。SSH配置文件应如下所示：

Host jump
 User myuser
 IdentityFile /home/vsts/work/_temp/key
 Hostname server.host
 Port xxx

Host myserver
 User myuser
 Port xxx
 IdentityFile /home/vsts/work/_temp/key
 ProxyCommand ssh -W %h:%p jump

由于我无法使用Install SSH Key任务的“Add entry to SSH config”部分来添加这些配置，因此我使用“Copy Files”作业将相应的SSH配置文件复制到/home/vsts/.SSH。我在“命令行脚本”任务中测试了执行

ssh-vvv

的配置，代理似乎能够成功连接到服务器：

然而，当SSH部署任务尝试连接时，我收到以下异常：

2020-09-02T12:02:40.8497381Z ##[error]Failed to connect to remote machine. Verify the SSH service connection details. Error: Error: getaddrinfo EAI_AGAIN <server>:<port>.

2020-09-02T12:02:40.8497381Z##[错误]无法连接到远程计算机。验证SSH服务连接详细信息。错误：错误：getaddrinfo EAI\u再次：。

SSH部署任务使用的服务连接正确。我怀疑这与SSH配置有关，因为getaddrinfo错误表明远程服务器的DNS解析失败

我知道我可以尝试使用私有代理池，但我想把它作为最后一个资源。是否有人建议我如何修复该错误？

也许您可以参考此内容，看看是否有帮助。尝试更改另一个端口。我以前看过那篇文章，但端口是正确的。实际上，我可以使用“命令行”任务和ssh-t命令连接到远程服务器，以执行我想要执行的任务。这意味着安装SSH密钥工作正常。我想问题在于“SSH部署”任务如何处理自定义SSH配置
