Jenkins SSH 管道步骤——com.jcraft.jsch.JSchException：私钥无效：[B@84d6b5c
Jenkins SSH Pipeline Steps -- com.jcraft.jsch.JSchException: invalid privatekey: [B@84d6b5c
我正在尝试在远程机器上执行 ssh 命令。
我是 运行 jenkins 作为 Ubuntu
上的一项服务
遵循的步骤
1 -- 已安装 ssh-steps-plugin
2 -- 在我的 jenkins master 上，我从 jenkins 用户生成了 ssh 密钥，并将 public 密钥复制到远程主机，我能够使用此密钥登录到远程主机

3 -- 创建了一个全局凭证来保存用户名和私钥
4 -- 使用以下 Jenkinsfile
创建了一个简单的管道
pipeline {
agent any
stages{
stage("SSH-Test"){
steps{
script{
withCredentials([sshUserPrivateKey(
credentialsId: "ssh-k8s-lb",
keyFileVariable: 'sshKey',

)]) {
def remote = [:];
remote.name = 'k8s-lb';
remote.host = '192.168.30.2';
remote.user = sshUser;
remote.identityFile = sshKey;
remote.allowAnyHosts = true;
sshCommand remote: remote, command: "ls -lrt"
}
}
}
}
