本地 Jenkins 安装没有 Docker 权限

Question

我在 Ubuntu 19.04 机器上安装了 Docker (19.03.3) 和 Jenkins（来自 https://jenkins.io/download/ 的 2.190.2 LTS）。然后我创建了一个从我创建的示例 Git 存储库加载 Jenkinsfile 的管道。一切正常，直到 Jenkins 指示 Docker 拉取图像。响应是系统没有权限这样做。我已经将我的系统用户添加到 docker 组 (sudo usermod -aG docker $USER) 并在我的终端中成功测试了 docker pull node:6-alpine。但是詹金斯还是失败了。

有人知道问题出在哪里吗？我想这不是很复杂，而是典型的配置错误。

Jenkins 管道控制台输出：

您的 Jenkins 没有运行与 dockers 用户。它运行与用户 jenkins 相关。因此，为了允许用户 jenkins 创建 Docker 容器，命令应如下所示：

sudo usermod -aG docker jenkins
