Question

我正在尝试使用Jenkins中的声明性管道从Dockerfile构建一个docker镜像。我成功地添加了“jenkins＆＃39;用户到docker组，并且可以运行＃docker run hello-world＆＃39;作为jenkins用户手动。但是，当我尝试通过管道进行构建时，我甚至无法运行“docker run hello-world＆＃39;”

从管道：

[workspace] Running shell script
+ whoami
jenkins
[workspace] Running shell script
+ groups jenkins
jenkins : jenkins docker
[workspace] Running shell script
+ docker run hello-world
docker: Got permission denied while trying to connect to the Docker 
daemon socket at unix:///var/run/docker.sock: Post 
http://%2Fvar%2Frun%2Fdocker.sock/v1.30/containers/create: dial unix 
/var/run/docker.sock: connect: permission denied.

手动抨击詹金斯并切换到詹金斯＆＃39;用户：

*********@auto-jenkins-01:~$ sudo su - jenkins -s/bin/bash
jenkins@auto-jenkins-01:~$ docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
 3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

其他一些有用的信息：Jenkins正在从VM运行。

需要通过编辑/ etc / default / docker并添加以下内容，为jenkins用户组权限设置docker unix socket：

DOCKER_OPTS=' -G jenkins'

Jenkins管道无法构建docker镜像
