解决pipline找不到docker命令:/Users/beck/.jenkins/workspace/locust_test@tmp/durable-884e1b18/script.sh: line 1: docker: command not found

问题一:/Users/beck/.jenkins/workspace/locust_test@tmp/durable-884e1b18/script.sh: line 1: docker: command not found

完整的pipeline如下,在docker hub上我打包了locust的运行环境locust:v1,这时候通过本地的jenkins去驱动本地的docker拉取镜像

pipeline { agent { docker { image 'docker.io/beck123/locust:v1'} } stages { stage('Test') { steps { sh 'docker images' } } } }

实际上发现build的console出现报错

Started by user admin [Pipeline] Start of Pipeline [Pipeline] node Running on Jenkins in /Users/beck/.jenkins/workspace/locust_test [Pipeline] { [Pipeline] isUnix [Pipeline] withEnv [Pipeline] { [Pipeline] sh + docker inspect -f . docker.io/beck123/locust:v1 /Users/beck/.jenkins/workspace/locust_test@tmp/durable-884e1b18/script.sh: line 1: docker: command not found [Pipeline] isUnix [Pipeline] withEnv [Pipeline] { [Pipeline] sh + docker pull docker.io/beck123/locust:v1 /Users/beck/.jenkins/workspace/locust_test@tmp/durable-ef3eab12/script.sh: line 1: docker: command not found [Pipeline] } [Pipeline] // withEnv [Pipeline] } [Pipeline] // withEnv [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline ERROR: script returned exit code 127 Finished: FAILURE

解决办法

参考stack overflow上的这篇文章:docker command not found in local jenkins multi branch pipeline,里面说到

The solution is to add the following line into the /usr/local/Cellar/jenkins-lts/2.176.3/homebrew.mxcl.jenkins-lts.plist file so that Jenkins able to find the docker command from the host machine.

<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>

我本地的地址是:/usr/local/Cellar/jenkins-lts/2.346.3/homebrew.mxcl.jenkins-lts.plist,直接修改后然后brew services restart jenkins-lts即可

问题二:+ docker images /Users/beck/.jenkins/workspace/locust_test@tmp/durable-195d79d3/script.sh: 1: docker: not found [Pipeline] }

如果仔细看console的报错信息,就会发现这个命令是在容器内部执行的,容器内部没有安装docker,所以出错了

这时候可以输出下python的版本,可以看到成功了

pipeline { agent { docker { image 'docker.io/beck123/locust:v1'} } stages { stage('Test') { steps { sh ''' python --version ''' } } } }
Jenkins does not seem to be running inside a container $ docker run -t -d -u 501:20 -w /Users/beck/.jenkins/workspace/locust_test -v /Users/beck/.jenkins/workspace/locust_test:/Users/beck/.jenkins/workspace/locust_test:rw,z -v /Users/beck/.jenkins/workspace/locust_test@tmp:/Users/beck/.jenkins/workspace/locust_test@tmp:rw,z -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** docker.io/beck123/locust:v1 cat $ docker top a29a24779a958fbece3102def3f1bda29cf80f467672609f84273aae27c7b480 -eo pid,comm [Pipeline] { [Pipeline] stage [Pipeline] { (Test) [Pipeline] sh + python --version Python 3.8.16 + ls -al total 4
