Failed to start wolkenkit

I try to run wolkenkit (v3.1.0) on Ubuntu 18.04 with nodejs v. node v10.13.0 using the official tutorial, but the framework complains when I try to start it within the sample chat application directory:

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

Docker is set up up and running:

$ 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

   CGroup: /system.slice/docker.service
           └─11342 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

and with the required version:

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

Is there anything I'm forgetting here?

Solution

  • Thanks to the comments, I've figured out that docker version --format "{{json .}} required by wolkenkit doesn't run correctly without root privileges.

    Invoking wolkenkit with sudo wolkenkit start solved the issue.
