在GKE上的kubernetes集群中使用Jenkins Docker插件

2023年2月7日 296次阅读

我按照这个很棒的教程在我的GKE kubernetes集群上安装Jenkins,然后开始使用CI.

一切都很顺利,直到我尝试在我的管道中使用docker插件.

这是我添加到我所引用的github项目中的问题的链接：

https://github.com/GoogleCloudPlatform/continuous-deployment-on-kubernetes/issues/65

当我尝试使用这样的docker插件时：

stage "Prepare environment"
docker.image('node:4.1.2').inside {
    print "inside a node server"
    sh("echo test");  
    //sh("npm install");      
  }

我收到以下错误：

[Pipeline] stage (Prepare environment)

[Pipeline] sh

基本上这个：

java.io.IOException: Failed to run image 'node:4.1.2'. Error: docker: Error response from daemon: mkdir /root/workspace: read-only file system.

在我上面指定的链接中进行更多调查.
在这种情况下,在docker中使用docker似乎很棘手.
我是jenkins的新手,但我想它必须是一种让docker插件在这种情况下工作的方法(GKE kubernetes集群)

非常感谢提前

最佳答案 我通过Jenkins插件远离码头“抽象”.您可以直接执行shell命令来执行docker工作负载,例如：

sh "docker build -t $SOME_NAME:$GIT_COMMIT_SHA ."
sh "docker run .."

或者更具体地说是你的粘贴：

sh "docker run -d --name node node:4.1.2"
sh "docker exec -it node /bin/sh -c 'npm install'"
