jenkins 管道中的 docker.image.inside 錯誤：無法運行程序“docker”：錯誤=2，沒有這樣的文件或目錄

Question

我創建了一個 Jenkins 管道項目，它應該在 newman 容器內運行 newman 命令。 Jenkins 在 Kubernetes 中的一個容器中運行。 我可以在我的管道中使用 docker.pull() 命令拉取圖像而沒有任何問題，但是當我想使用 docker.image("postman/newman").inside {...} 命令在我的容器內運行命令時，我收到以下錯誤消息：

似乎缺少 docker，但我不明白為什么我能夠執行 docker.image 或 docker.pull 如果是這種情況。 任何人都可以就我做錯了什么給我一些建議嗎？

我嘗試使用不同的圖像，但出現相同的錯誤消息。

我的管道如下所示：

pipeline {
    agent any
    environment {
        USER_BIN = '/var/jenkins_home/user-bin'
        DOCKER_HOST = 'unix:///var/run/docker.sock'
        DOCKER_CONFIG = '/var/jenkins_home/.docker'
    }
    stages {
        stage ('TestInsideContainer') {
            steps() {
                script {
                    env.PATH = "${tool 'docker'}/bin:${env.PATH}"
                    newmanimage=docker.image("postman/newman")
                    newmanimage.pull()
                    newmanimage.inside() { 
                        sh 'newman --version'
                    }
                }
            }
        }
    }
}

發生這種情況是因為在啟動代理時，PATH 設置不正確。 我很難找到解決方案。 答案不在管道中，而是在啟動 Jenkins 代理時設置 PATH。

這應該有幫助。
