linux – 为什么Jenkins用户没有权限访问Docker unix套接字？

我已经将jenkins用户添加到docker组,认为它允许Jenkins作业运行Docker命令.如果我切换到jenkins用户,我可以验证它是否有效(手动)：

ubuntu@hostname:~$ps aux | grep java
jenkins   2210  9.5  7.5 1950316 292896 ?      Sl   00:01   1:00 /usr/bin/java -jar /data/jenkins/jenkins-1.586.war --httpPort=8080 -Xloggc:/var/log/jenkins/gc.log
ubuntu@hostname:~$getent group docker
docker:x:999:jenkins
ubuntu@hostname:~$ls -la /var/run/docker.*
-rw-r--r-- 1 root root   4 Oct 23 18:32 /var/run/docker.pid
srw-rw---- 1 root docker 0 Oct 23 18:32 /var/run/docker.sock
ubuntu@hostname:~$sudo su -s /bin/bash jenkins
jenkins@hostname:/home/ubuntu$docker ps
CONTAINER ID        IMAGE                      COMMAND                CREATED             STATUS              PORTS                     NAMES

但是,在Jenkins构建/作业期间,它没有权限：

这是Docker 1.3.0和Ubuntu 14.04.1.有什么线索吗？

解决方法

DOCKER_OPTS=' -G jenkins'

在ubuntu / etc / default / docker中是docker配置文件.
