如何解决Jenkins触发时的Docker权限错误

我的Jenkins不是在Docker容器中运行,只是传统安装到VPS。执行简单的test project时出现以下错误。我使用的是Ubuntu 14,java 7和稳定的Jenkins。我尝试了我可以在谷歌上找到的所有方法,但无法让它工作。

我正在尝试执行此shell

docker build --pull=true -t nick/hello-jenkins:$GIT_COMMIT .

代码更改后。

这是错误:

我可以在控制台中以root身份运行'docker'没问题,为什么jenkins无法尝试运行'docker'的shell命令?到底是怎么回事?完全糊涂.......

在您的VPS服务器终端中,执行此操作将您的jenkins用户添加到泊坞窗组:

sudo usermod -aG docker jenkins

然后重新启动jenkins服务器以刷新组。

考虑到这可能产生的任何安全问题:

  

警告:docker组授予与root用户等效的权限。有关这将如何影响系统安全性的详细信息,请参阅Docker Daemon Attack Surface。

请参阅docs

编辑(由@iger提及):只需确保从命令行重启Jenkins(即sudo service jenkins restart),但不要通过其余端点重启(http:/// restart)

  1. 按照描述here
  2. 将用户添加到泊坞窗组
  3. 使用此命令启动jenkins: docker run -d -u root --restart on-failure -p "8080:8080" -p "50000:50000" -v $PWD/jenkins-data:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkinsci/blueocean
  4. 需要

    root用户,因为没有它,您将无法执行root任务,例如:apk update && apk install ...

运行

sudo usermod -aG docker jenkins

然后

sudo service jenkins restart

对我来说很完美。
