I struggled to discover information on how to specify a kubernetes
version when starting minikube. Ultimately, I found the answer through
searching Github issues, and also running `minikube start --help`.
Given it seems like a fairly common task, I think it could be useful to
include it in the getting started documentation.
* update scratch.md for issue #4068
Issue #4068 details the dangers of recommending single etcd instance.
This will likely need to be expanded into better "highly available" cluster documentation
* Refactor list style
* fix ordered list
* fix unordered list
* ul
* add back shell
* Remove self-links with domain names in docs
Fixes#4191. Skipping the tutorials we import from kubernetes/examples.

Addresses the work described at #4134.
- Remove /docs/samples page: This page mostly had links to examples on
kubernetes/kubernetes (examples dir) which is now at kubernetes/examples
repository. It was linking to README.md files for tutorials. Now removing
this page as we are moving tutorials from kubernetes/examples to here:
- Create redirects from /docs/samples/ to /docs/tutorials/ (both JS and
redirect_from).
- Deprecate "MEAN Stack" tutorial: This tutorial overlaps quite a bit with
existing "maintained" examples and has been out-of-date for a while.
Creating an external redirect to its original and more up-to-date location:
https://medium.com/google-cloud/running-a-mean-stack-on-google-cloud-platform-with-app-engine-and-mongolab-4bbd2040ea75
- Import README.md files of maintained examples (guestbook, wordpress+mysql and
cassandra) to this repository and serve them under /docs/tutorial.
- Update /docs/tutorials ToC:
- Link to imported tutorials.
- Fix missing articles on sidebar (_data/tutorials.yml) and make the tutorials
listed on tutorials/index.md available on the sidebar (closes#4007).

* Update scratch.md: include download binary tarball
As `kubernetes-server-linux-amd64.tar.gz` is not provided with the tarball now, an extra step is required.
* Updated scratch.md to follow review comments
* rename kargo to kubespray in getting started docs
* remove old kargo guide, update link to kubespray doc
* update setup.yml with new kubespray pointer
Using `--no-check-certificate` is, frankly, dangerous and we shouldn't be recommending that users use it. Not without a good reason, anyway.
If a user's system is sufficiently broken that they are getting certificate validation problems during this step, I fail to see how it is our problem to tell the user to overcome that. Let's focus on installing Kubernetes here.
Now that we have new repositories to house RPMs for other architectures,
and are populating them with new releases, we should advertise them in
the kubeadm getting started instructions.
Similar to the pod-network-cird= issue, with no = there is no immediate problem but it causes trouble along the way (i.e. I wasn't able to access the dashboard via kubectl proxy)
Wasted hours today trying to get kubeadm working on a Ubuntu VM. The culprit is a missing = for the pod-network-cidr parameter to the kubeadm init command when using calico. Without it kube-dns refused to start, oddly enough pods had 10.244.0.0 network setup but somehow it was failing sending a request to destroy and recreate the pod.
Here's the events for the kube-dns pods if someone's interested.
