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.
我正在尝试执行这个shell
docker build --pull=true -t nick/hello-jenkins:$GIT_COMMIT .
代码更改后.
这是错误：
Got permission denied while trying to connect to the Docker daemon socket at unix: ....

我可以在控制台中运行’docker’作为root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？完全迷茫…….
在您的VPS服务器终端中,执行此操作以将您的jenkins用户添加到docker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：
Warning: The docker group grants privileges equivalent to the root user. For details on how this impacts security in your system,see Docker Daemon Attack Surface.
请参阅docs
编辑(由@iger提到)：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)
