【问题描述】：
我正在尝试使用 Jenkins 中的声明性管道从 Dockerfile 构建 docker 映像。我已成功将“jenkins”用户添加到 docker 组，并且可以手动以 jenkins 用户身份运行“docker run hello-world”。但是，当我尝试通过管道构建时，我什至无法运行 'docker run hello-world'：
来自管道：
[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.
手动进入 Jenkins 并切换到“jenkins”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。
