If anyone wonders why it just shows a blank page, the error code is: 503 Service Unavailable: Back-end server is at capacity TL;DR: We’ve slashdotted it.

Done. Should be working now.

You might want to put this behind kubernetes so you can scale it easier... It's down again.

This is cool but I'm a bit unsure how to actually use this. Kubectl doesn't seem to be able to connect to the server from within the terminal. It just gets: `The connection to the server localhost:8080 was refused - did you specify the right host or port?`

It should work if you are on the master node

Yeah. Too much traffic in a short period of time. Sorry about that.

https://www.katacoda.com/learn is a pretty great site, that also has a "playground" mode for Kubernetes available (as well as others)

I've tried the katacoda kubeadm tutorial but it didn't work for me

I'm looking for similar, but want to run containers on bare metal, not inside virtual box or similar.

I used kubeadm to set up a small cluster on Online.net’s cheap dedicated machines. It works quite well.

I use this for a "full cluster"

If you want bare metal, there's a few good ways to roll your own.

I just used this official guide from CoreOS to set it up on Vagrant/virtualbox: https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagr.... It was pretty straightforward.
