docker: command not found ( mac mini ) only happen

问题:

I'm facing this weird problem , struggling to solve since almost couple of days.

Working: On mac mini command prompt , I switch to jenkins user and can run docker command without any problem.

Not Working: but when I run a jenkins job , inside shell command step docker is not recognized.

I'm getting error

docker: command not found

docker --version

But mentioning explicit path of docker , does work

/Users/buildserver/Library/Group\ Containers/group.com.docker/bin/docker --version

Question : Why docker command can't look into correct path ?

Permissions

lrwxr-xr-x 1 buildserver staff 71 Oct 14 10:44 docker -> /Users/buildserver/Library/Group Containers/group.com.docker/bin/docker

jenkins uses is part of staff group.

Thanks in advance.

回答1:

The PATH which Jenkins jobs start with isn't the same as the path which the Jenkins user sees in bash. In the Jenkins UI you can edit the environment varables (from Manage Jenkins/Configure System), and add the Docker folder to PATH:

PATH -> $PATH:/Users/buildserver/Library/Group\ Containers/group.com.docker/bin/

For others (Late but worthy), I installed Jenkins via Brew, so I add Docker's path to the file below: /usr/local/Cellar/jenkins-lts/2.176.3/homebrew.mxcl.jenkins-lts.plist (Whole file looks like below)

<?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>/usr/local/opt/jenkins-lts/libexec/jenkins.war</string>
      <string>--httpListenAddress=127.0.0.1</string>

    <key>RunAtLoad</key>
    <true/>
    <key>EnvironmentVariables</key>
    <dict>
      <key>PATH</key>
      <string>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Docker.app/Contents/Resources/bin/:/Users/Kh0a/Library/Group\ Containers/group.com.docker/Applications/Docker.app/Contents/Resources/bin</string>
    </dict>
  </dict>
</plist>

Then restart Jenkins' service:

brew services restart jenkins-lts
