Jenkins ： 无法运行程序 “docker”： error=2， 没有这样的文件或目录

java docker jenkins
2022-09-05 00:39:45

我已经在我的本地计算机上安装了Jenkins，该机器在MacOS High Sierra上运行并安装了docker。我正在尝试运行一个使用 docker 的简单管道示例。我已将以下行添加到管道中：

pipeline {
    agent {
        docker { image 'node:7-alpine' }
    }
    stages {
        stage('Test') {
            steps {
                sh 'node --version'
            }
        }
    }
}

然后从WebGUI中，我点击了现在构建，它失败了。控制台输出显示错误如下：

为什么会发生这种情况？在 Jenkins 文档中，他们只给出了这种语法，没有提到其他任何内容。


答案 1

我遇到了与上面相同的问题。我不确定我的情况是否与您的情况完全相同，但TL;DR是您需要确保Docker可用于Jenkins正在使用的PATH变量。特别是它启动的那个，可以在Jenkins Home -> Manage Jenkins -> System Information下看到。

就我而言，我在Mac上，并通过Homebrew安装了Jenkins。为了解决这个问题，我编辑了该文件并将其更改为以下内容：/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>homebrew.mxcl.jenkins-lts</string>
    <key>ProgramArguments</key>
    <array>
      <string>/usr/libexec/java_home</string>
      <string>-v</string>
      <string>1.8</string>
      <string>--exec</string>
      <string>java</string>
      <string>-Dmail.smtp.starttls.enable=true</string>
      <string>-jar</string>
      <string>/usr/local/opt/jenkins-lts/libexec/jenkins.war</string>
      <string>--httpListenAddress=127.0.0.1</string>
      <string>--httpPort=8080</string>
    </array>
    <key>EnvironmentVariables</key>
    <dict>
      <key>PATH</key>
      <string>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
    </dict>
    <key>RunAtLoad</key>
    <true/>
  </dict>
</plist>

这里重要的部分是：

    <key>EnvironmentVariables</key>
    <dict>
      <key>PATH</key>
      <string>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
    </dict>

在我的情况下，可以在 .docker/usr/local/bin


答案 2

我最近在macOS上遇到了同样的问题。通过将以下行添加到/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist

    <key>EnvironmentVariables</key>
    <dict>
      <key>PATH</key>
      <string>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
    </dict>

它还需要重新启动 jenkins 。brew services restart jenkins-lts

顺便说一句，在 jenkins Web GUI 中添加 PATH 环境并不能解决问题。它在某些方面起作用，并且使整个过程失败，这使它更加混乱并误导了我太多。
