[英]Jenkins : Cannot run program “docker”: error=2, No such file or directory
I have installed Jenkins on my local machine which runs on MacOS High Sierra and have docker installed .我已经在我的本地机器上安装了 Jenkins,它在 MacOS High Sierra 上运行并安装了 docker。 I am trying to run a simple pipeline example which uses docker.
我正在尝试运行一个使用 docker 的简单管道示例。 I have added the following lines to pipeline :
我在管道中添加了以下几行:
pipeline {
agent {
docker { image 'node:7-alpine' }
}
stages {
stage('Test') {
steps {
sh 'node --version'
}
}
}
}
Then from the WebGUI, I click on build now and it is failing.然后从 WebGUI 中,我单击“立即构建”但它失败了。 Console output showing the error as follows :
显示错误的控制台输出如下:

Why this is happening ?为什么会这样? In the Jenkins documentation, they are only given this syntax and doesn't mentioned about anything else.
在 Jenkins 文档中,他们只给出了这种语法,没有提到其他任何东西。
I hit the same problem as above.我遇到了与上面相同的问题。 I am not sure that my case is exactly the same as your but the TL;DR is that you need make sure that Docker is available to the PATH variable Jenkins is using.
我不确定我的情况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。 Specifically the one it starts up with, which can be seen under Jenkins Home -> Manage Jenkins -> System Information .
特别是它启动的那个,可以在Jenkins Home -> Manage Jenkins -> System Information下看到。
In my case, I am on a Mac and installed Jenkins through Homebrew.就我而言,我在 Mac 上并通过 Homebrew 安装了 Jenkins。 To fix the issue I edited the
/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
file and changed it to the following:为了解决这个问题,我编辑了
/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
文件并将其更改为以下内容:
<?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>
The important part here is:这里的重要部分是:
<key>EnvironmentVariables</key>
<dict>
<key>PATH</key>
<string>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
</dict>
in my case, docker
is available at /usr/local/bin
.就我而言,
docker
在/usr/local/bin
可用。
I ran into some serious trouble with this too so I wanted to post my solution since I have not seen it around anywhere.我也遇到了一些严重的问题,所以我想发布我的解决方案,因为我没有在任何地方看到它。
My setup was: A Mac Mini running Mac OS Sierra with jenkins and docker both installed locally.我的设置是:运行 Mac OS Sierra 的 Mac Mini,jenkins 和 docker 都安装在本地。 Jenkins could not call docker in groovy scripts, but the shell had access to docker commands.
Jenkins 无法在 groovy 脚本中调用 docker,但 shell 可以访问 docker 命令。
Solution:解决方案:
Open your Groovy script where you want to call your docker installation and surround your docker calls in a block statement like this:打开您要调用 docker 安装的 Groovy 脚本,并将您的 docker 调用包含在如下块语句中:
docker.withTool('') { //whatever docker commands you wish to run here } docker.withTool('') { //任何你想在这里运行的 docker 命令 }
I enncounter the same problem on macOS recently.我最近在 macOS 上遇到了同样的问题。 It is solved by adding following lines to
/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
通过
/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
添加到/usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
来解决
<key>EnvironmentVariables</key>
<dict>
<key>PATH</key>
<string>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
</dict>
It also need restart jenkins brew services restart jenkins-lts
.它还需要重启 jenkins
brew services restart jenkins-lts
。
By the way, add PATH environment in jenkins web GUI don't fix the problem.顺便说一句,在 jenkins web GUI 中添加 PATH 环境并不能解决问题。 It work in some part and failed the whole process which make it more confused and mislead me too much.
它在某些部分起作用并且整个过程都失败了,这使它更加困惑并误导了我太多。
