docker - 启动 wolkenkit 失败

Question

我尝试使用 nodejs v. node v10.13.0 在 Ubuntu 18.04 上运行 wolkenkit (v3.1.0)
使用官方tutorial ，但是当我尝试在示例聊天应用程序目录中启动它时，框架会提示:

  $ wolkenkit start --verbose
  Starting the application...
  Failed to reach Docker server.
  Failed to start the application.
  Docker not reachable.
  DockerNotReachable: Docker not reachable.

Docker 已设置并运行:

$ sudo service docker status
● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: active (running) since Tue 2019-07-09 18:47:51 CEST; 9min ago
     Docs: https://docs.docker.com
 Main PID: 11342 (dockerd)
    Tasks: 22
   CGroup: /system.slice/docker.service
           └─11342 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

并使用所需的版本:

$ docker --version
Docker version 18.09.7, build 2d0083d

我在这里忘记了什么吗？

感谢评论，我发现 docker version --format "{{json .}} wolkenkit 所需的在没有 root 权限的情况下无法正常运行。

使用 sudo wolkenkit start 调用 wolkenkit解决了这个问题。
