Jenkins管道失败git克隆使用sshaent插件？

Question

Jenkinsssh代理插件

我创建了一个新的Ubuntu构建节点，名为test fleet。我在节点中有以下文件

/home/ubuntu/.gitconfig
------------------------
[user]
(tab)name = myUser
(tab)email = [e-mail]

$ ls -al .gitconfig
-rw-r--r-- 1 ubuntu ubuntu   58 Jan 25 04:27 .gitconfig

现在我有一条Jenkins管道可以做到这一点

node('test-fleet') {
   stage('test git') {
     sshagent(credentials: ['myUser-creds']) {
       sh """
          export GIT_SSH_COMMAND=\"ssh -v\"
          git ls-remote [e-mail]:project/myrepo.git
       """
     }
   }
}

我在我工作的控制台上得到这个

我知道我使用了正确的信条，并且存储库存在。我有另一个构建节点，它在那个节点上工作，所以我知道我的Jenkins设置正确，问题出在新的构建节点上。

有什么解决办法吗？

Answer 1

首先，检查哪个用户拥有Jenkins。您可以通过列出jenkins安装目录的所有者（默认为/var/lib/jenkins）来找到它。然后与该用户登录并签出。该用户的ssh文件夹。由于Jenkins正在使用SSH进行结账，根据这里的回答，您在$HOME/中应该会遇到问题。ssh/已知的_主机。遵循为运行jenkins的正确用户提供的链接指南，使git签出工作。问题是，myUser实际上没有任何ssh存储库来检查ssh密钥。在计算机中创建myUser，然后添加。ssh文件夹，或使用其他用户。

Answer 2

首先检查执行git ls remote时是否使用相同的键[e-mail]：project/myrepo。git在一个会话中使用与运行Jenkins的用户相同的用户。

并检查myUser-creds是保护SSH私钥的实际密码短语（而不是密码：密码短语）。对于SSH，没有用户名/密码中的“凭据”。
