TestContainers 框架无法访问 docker deamon

Question

我正在尝试让testcontainers构建一个 mariadb 实例，如下所示：

connection = DriverManager.getConnection("jdbc:tc:mariadb:5.6.23:///datavault");

但我得到的是这个日志：

我正在使用docker it self 提供的 ubuntu 存储库中的默认 docker 安装。
假设 testcontainers 无法读取 /var/run/docker.sock 文件，
我将我的用户添加到docker组，但错误是一样的！

另外我尝试了 快速入门示例，但仍然出现相同的错误！

非常感谢您的帮助，
如果您需要更多信息，请告诉我！

有时它可以如此简单：
添加到 docker 组是正确的想法
但我忘记了添加到组的事实
仅在新登录用户后接管！

之后，我收到一个新错误，但这是另一个主题。
抱歉打扰了！
