Adicionei o jenkins
usuário ao docker
grupo pensando que permitiria que os trabalhos de Jenkins executassem comandos do Docker. Se eu mudar para o jenkins
usuário, posso verificar se funciona (manualmente):
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
No entanto, durante uma construção / trabalho do Jenkins, ele não tem permissão:

Isso ocorre com o Docker 1.3.0 e o Ubuntu 14.04.1. Alguma pista?
