Question

我发现DolphinDB现在支持使用Docker容器进行快速集群部署，并且我遵循了gigthub上的指南：https://github.com/dolphindb/Tutorials_CN/blob/master/docker_deployment.md来部署具有DolphinDB Docker软件包的集群。但是我遇到了一个问题。我看了其他任何问题，但找不到自己的解决方案。

问题出在这里

xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ docker -v
Docker version 18.09.3, build 774a1f4
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ docker-compose --version
docker-compose version 1.24.0, build 0aa59064
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ docker build -t ddb:latest ./
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

我尝试重新启动docker：

xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ sudo service docker restart
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.

然后我检查了此内容：

xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ systemctl status docker.service

您可以尝试使用/var/lib/docker删除sudo rm -rf /var/lib/docker并尝试重新启动docker吗？

您将丢失存储的图像。

使用Docker尝试快速集群部署：无法通过unix：///var/run/docker.sock连接到Docker守护程序。泊坞窗守护程序正在运行吗？
