無法從 docker 容器 SSH 到遠端伺服器

在我的主機伺服器上，我的使用者擁有生成的私鑰和公鑰。我已將公鑰值複製到我的遠端伺服器authorized_keys文件中。我已將新的 docker 容器實例映射為使用 .ssh 文件夾作為卷並將網路設置為主機的網路。

-v /home/jenkins/.ssh:/home/jenkins/.ssh --network host'

現在我嘗試在容器內對遠端電腦進行 SSH 身份驗證。

ssh -vvv -o StrictHostKeyChecking=no jenkins@10.7.175.143

我的使用者沒有 SSH 密碼。SSH伺服器端的輸出：

sshd: Failed none for jenkins from 10.7.148.219 port 42058 ssh2
sshd: Failed password for jenkins from 10.7.148.219 port 42058 ssh2

客戶端輸出：

我可以以某種方式從 docker 容器中驗證我的身份嗎？

從您的調試輸出中，您可以看到，由於您將ssh命令作為執行，它會在的主文件夾而不是主文件夾root中搜尋 ssh 密鑰。root``jenkins

debug1: Trying private key: /root/.ssh/id_rsa
debug3: no such identity: /root/.ssh/id_rsa: No such file or directory

您應該通過在命令中添加-i <identity_file>標誌來提供私鑰的位置。ssh
