问题
I'm trying to download the OpenShift Origin server with this tutorial in order to be able to increase amount of memory dedicated to the build. Yet Whil following the tutorial I tried to launch the server but got an error about Kubelet. I have Ubuntu 16.04.
~/openshift-origin-server-v3.9.0-191fece-linux-64bit$ sudo ./openshift start
....
F0622 17:00:24.659470 14610 server.go:173] failed to run Kubelet: failed to create kubelet: failed to get docker version: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Should I install it ? I don't think it was written in the tutorial. Sorry if that sounds dumb, I'm new to web deployment.
