"Create 3 hosts and call them node-master, node-1 and node-2."

Needs a bit of explanation!

If I do:

$ docker run --name node-master -i -t ubuntu /bin/bash

And then do your suggested apt stuff, the kubeadm apt isn't found.

$ docker run -i -t ubuntu:16.04 /bin/bash

It was a hell of a job getting kubadm installed. Your stanza didn't work needed to add "deb http://apt.kubernetes.io/ kubernetes-xenial main" manually.

kubeadm init needed --ignore-preflight-errors=all and even then, ended with a load of:

[WARNING ImagePull]: failed to pull image k8s.gcr.io/kube-apiserver:v1.12.2: output: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

, error: exit status 1

The docker daemon isn't running despite installing docker.

for the part 1 of the lab, you can download a preconfigured machine from here

according to the error message, it seems like the docker service isn't running

inside the node-1 and node-2

for SERVICES in kube-proxy kubelet  docker; do
    systemctl restart $SERVICES
    systemctl enable $SERVICES
    systemctl status $SERVICES
done

to see if the docker daemon is already running systemctl status docker docker info

to restart the services in the node-master

for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler flanneld; do
	systemctl restart $SERVICES
	systemctl enable $SERVICES
	systemctl status $SERVICES
done

and plz make sure the DNS service is already configured another tip: if you are running the cluster's machine has more than one NIC, then k8s will use the one which has the default route

kubeadm must be run from the node-master

Why the nodes? GitHub says to do the kube stuff on the master.

Trying your image now. Oh, link didn't work.

exactly, the kube staff should be on the master. and you have to administrate the nodes using kubectl from the master. i didn't upload a preconfigured VM. i used the GCP to create k8s cluster. if you would like to create k8s cluster by yourself try to download this ubuntu iso and follow the steps in the option.

I will be glad to help you create ur cluster
