如何使用 ssh 命令将值放入 Jenkinsfile 中的变量

Question

我想在 Jenkins 中创建一个管道，它获取使用 sshCommand 执行的命令的值。我在远程服务器上有一个这样的文件:

VALUE 11

这是我的管道：

pipeline {
agent any

stages {
    stage('Get Init') {
        steps {
            withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId:'xxxxxxx', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
                script {
                    def remote = [:]
                    remote.name = 'xxxxxx'
                    remote.host = 'xxxxxx'
                    remote.user = USERNAME
                    remote.port = 22
                    remote.password = PASSWORD
                    remote.allowAnyHosts = true
                    sshCommand remote: remote, command: "init=$(cat /var/log/myFile |  grep VALUE | awk '{print $2}')"
                }
            }
        }
    }
    stage("Test") {
        steps {
            script {
                    test = sh(script "echo $init")
                }
            }
        }
    }

    
}

}

我想在变量中获取“11”以便稍后在我的 Jenkinsfile 中进行比较。如何做到这一点？

您可以通过以下方式使用:
示例：
def Result = sshCommand remote: remote, command: "<Your command>"

# Declare variable init
def init
pipeline {
agent any
stages {
    stage('Get Init') {
        steps {
            withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId:'xxxxxxx', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
                script {
                    def remote = [:]
                    remote.name = 'xxxxxx'
                    remote.host = 'xxxxxx'
                    remote.user = USERNAME
                    remote.port = 22
                    remote.password = PASSWORD
                    remote.allowAnyHosts = true
                    # Execute your command and take return value in the init variable
                    init= sshCommand remote: remote, command: "cat /var/log/myFile |  grep VALUE | awk '{print $2}')"
                    echo "Initial Value: " + init
                }
            }
        }
    }
    stage("Test") {
        steps {
            script {
                    test = sh(script "echo ${init}")
                }
            }
        }
    }
  }
}
