如何在 Jenkins 管道中使用 SSH? [英] How do I use SSH in a Jenkins pipeline?

问题描述

我使用 Jenkins 管道模型定义定义了一些 Jenkins 作业，该定义构建 NPM 项目.我使用 Docker 容器来构建这些项目(使用带有只是 Node.js + npm + yarn).

I have some Jenkins jobs defined using a Jenkins Pipeline Model Definition, which builds NPM projects. I use Docker containers to build these projects (using a common image with just Node.js + npm + yarn).

构建结果包含在我使用 zip 管道命令压缩的 dist/ 文件夹中.

The results of the builds are contained in the dist/ folder that I zipped using a zip pipeline command.

我想使用 SSH/SCP(使用私钥身份验证)将此 ZIP 文件复制到另一台服务器.我的私钥添加到Jenkins环境(凭证管理器)中，但是当我使用Docker容器时，无法建立SSH连接.

I want to copy this ZIP file to another server using SSH/SCP (with private key authentication). My private key is added to the Jenkins environment (credentials manager), but when I use Docker containers, an SSH connection cannot be established.

我尝试添加 agent { label 'master' } 以使用主 Jenkins 节点进行文件传输，但它似乎使用新的 Git fetch 创建了一个干净的工作区，并且没有我构建的文件.

I tried to add agent { label 'master' } to use the master Jenkins node for file transfer, but it seems to create a clean workspace with new Git fetch, and without my built files.

在我尝试了 SSH 代理插件之后，我得到了这个输出:

After I tried the SSH Agent Plugin, I have this output:

Identity added: /srv/jenkins3/workspace/myjob-TFD@tmp/private_key_370451445598243031.key (rsa w/o comment)
[ssh-agent] Started.

unset SSH_AUTH_SOCK;
unset SSH_AGENT_PID;
echo Agent pid 1424 killed;
[ssh-agent] Stopped.
Host key verification failed.
lost connection

如何添加授权的远程主机?

How do I add a remote host as authorized?

推荐答案

我遇到了类似的问题.我没有使用标签master"，当我这样做时，我发现文件传输可以跨从设备进行:

I had a similar issue. I did not use the label 'master', and I identified that the file transfer works across slaves when I do it like this:

步骤 1 - 在远程主机服务器中创建 SSH 密钥，包括authorized_keys 的密钥

Step 1 - create SSH keys in a remote host server, include the key to authorized_keys

第 2 步 - 在 Jenkins 中使用 SSH 密钥创建凭证，使用来自远程主机的私钥

Step 2 - Create credential using SSH keys in Jenkins, use the private key from the remote host

使用 SSH 代理插件:

stage ('Deploy') {
    steps{
        sshagent(credentials : ['use-the-id-from-credential-generated-by-jenkins']) {
            sh 'ssh -o StrictHostKeyChecking=no [e-mail] uptime'
            sh 'ssh -v [e-mail]'
            sh 'scp ./source/filename [e-mail]:/remotehost/target'
        }
    }
}
