我按照此文档设置了SSH身份验证https://kgcoe-git.rit.edu/help/ssh/README#generating-a-new-ssh-key-pair
它以前曾经工作过，但是这次在新设置上我得到了Permission denied (publickey)错误
下面是ssh命令的调试输出

提前致谢。
我[email protected]: Permission denied (publickey)按照以下步骤解决了问题：
cat ~/.ssh/id_rsa.pubid_rsa.pub（公共密钥）复制到您的getlab`Setting-> SSH Keyscat ~/.ssh/id_rsaid_rsa（私钥）到`Code_repo-> git_auth-> id_rsa（私钥本地文件）注意：如果要root在DockerFile中使用用户，或者在随后使用的其他任何位置使用用户，请sudo su在运行上述命令获取root用户的公共密钥和私有密钥之前照顾机器用户。
