You might enjoy this guide[1]. It explains how to deploy and run a secure, fully functional Kubernetes cluster outside platforms like GCE or AWS. Provisioning and example manifests are provided as well.

Why you are not serving the site in S3 bucket? :] Or does it have some fancy server side functionality?

Now that I was finally able to load the site I must say I'd have liked to have had some basic tutorials to help me get started. It might haven't been in the scope of this site but surely it would have been nice. Also the recaptcha is just a kick in the balls when it starts asking to pick the right squares. I'd have been happy to sign in with G+ just to skip it.

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 can access the 'playground' exercise, but you have to sign up to the site to access the other tutorials.

This is the companion site to play-with-docker.com - which also has the captcha. OpenID login sounds like a good idea.

Yes - this has been doing fairly well and uses kubeadm on Ubuntu - https://blog.alexellis.io/kubernetes-in-10-minutes/

True, but it's a free signup and we don't send unwanted emails...

Hi, PWK co-author here. Indeed, Katacoda is a great site to learn technologies. With our playgrounds we're trying to accomplish a different purpose though. Here's a blog post that explains the idea better: https://medium.com/@marcosnils/introducing-pwk-play-with-k8s....

TL;DR: PWK is a platform composed by different components powered by the an open source core (https://github.com/xetorthio/play-with-docker) that allows the following:

* Try new features fast as it’s updated with the latest dev versions. * Setup clusters in no-time and launch replicated services. * Learn through it’s interactive tutorials (http://training.play-with-docker.com). * Allow to run advanced workshops that’d usually require complex setups. * Collaborate with community members to diagnose and detect issues by sharing your session URL.

The idea is to replicate real case deployments where you need to add/remove nodes to experiment with failures and things like that. You can also go through platform upgrades as PWK allows to run different versions of K8s in the same session.

Additionally, we're planning to launch a training site similar to Docker's (http://training.play-with-docker.com/) to enhance the experience soon. It'd be awesome to get the K8s community help with the content as it's very difficult to scale all this content by ourselves as an free project.

If you need help deploying K8s locally or in your own cloud provider, please let us know so we can help. This is still a very young project, but we think that with some help it could really help the community as it did for Docker.

I'd love to hear your feedback, bug reports are always welcome. We haven't heard of other problems.

Sure, sorry I didn't elaborate my previous comment, it was late here and after re-reading, it feels like a rant. What I meant was that I've tried following Katacoda's kubeadm tutorial (https://www.katacoda.com/courses/kubernetes/getting-started-...) but for some reason it seems not to be working for me. Both cluster nodes never get `ready` after finishing the tutorial, only the master one.
