<p>Dependency failed for Docker Application Container Engine. May 20 13:06:52 localhost systemd[1]: docker.service: Job docker.service/start failed with result 'dependency' when I do a systemctl status docker.</p>

<p>Using the CoreOS install documentation, Kubelet(master) all on same node.</p>

<p>Where would I start looking to debug this from?</p>

<p>I know it's a little late, but I think you need to ensure <code>flanneld.service</code> service is running. If you're following the CoreOS step-by-step documentation for building a Kubernetes cluster with CoreOS, then flanneld is a dependency for the docker engine.</p>

<p>If you made a systemd drop-in replacement in <code>/etc/systemd/system/docker.service.d/40-flannel.conf</code>, then that is most likely the case as evidenced here:</p>

<p><code>[Unit]
Requires=flanneld.service
After=flanneld.service</code></p>
