jenkinsdocker插件工作“权限被拒绝”的错误

我在Ubuntu 14.04机器上安装了CI环境，安装了Jenkins，Gitlab和docker runtime。 我configuration了一个项目myproject-hello-world（一个java / maven项目）和一个相应的jenkins作业，包含调用以下目标

(in Jenkins > myproject-hello-world job configuration page) Invoke top-level Maven targets clean package docker:build -DskipTests 

jenkins的工作失败，出现以下错误：

 [ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.2.3:build (default-cli) on project myproject-hello-world: Exception caught: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: org.newsclub.net.unix.AFUNIXSocketException: Permission denied (socket: /run/docker.sock) -> [Help 1] (see below for the whole console log) 

如果我只留下maven的clean package任务（即，删除docker：build插件，并保持其他一切不变），项目build设没有问题，所以我非常确定我的Jenkins + Jdk + Maven + Gitlabconfiguration不应该'没有任何问题。

另外，如果我在我的开发机器mvn clean package docker:build ，那么也可以正确地为我的项目创build一个docker镜像。 这应该排除在pom.xml或我的Dockerfile中的docker-maven插件configuration中的问题。

这是如何在Jenkins中configurationJekins Docker插件configuration>系统configuration>云/添加云：Docker部分我已经把下面的configuration

 Name docker Docker URL http://localhost:4243 Credentials: None 

不清楚我是否必须在“证书”部分添加某些内容（可能与“拒绝权限”错误有关，但如果我不知道应该在这里input什么凭证）

这是整个工作的控制台输出

在Docker插件说明页面https://wiki.jenkins-ci.org/display/JENKINS/Docker+Plugin有一个提示，我必须设置

 DOCKER_OPTS="-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock" 

在/ etc / default / docker文件中。 我做了，但没有改变。

Answer 1

如@chrx所述，这解决了我的问题：

直接在/etc/default/docker DOCKER_OPTS=' -G jenkins'添加DOCKER_OPTS=' -G jenkins'

非常感谢！
