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.

Fixes#3357. I'm removing this statement as it's not clear where it should
actually be pointing to...

This table of contents is redundant (it's also available from the side nav) and confusing (not clear if it's a copy of the side nav or contains additional information). Plus, it was out of sync with the actual table of contents (last section on GPU was missing). So, I think it's best to just remove it.
* Update link to Adding ImagePullSecrets to a service account
* Link to appropriate docs for Automatic Mounting of Manually Created Secrets
* Replace here w/ title of pages
* Syntax for Kubernetes version 1.6
Included 1.6 syntax change for declaration of init containers.
* Reorder services.yaml & add 1.5 syntax still works
* Corrected YAML headings & add syntax explanation
When -w option is not available for base64, for example, when using alpine Docker image.
`echo -n "<text>" | base64 | tr -d '\n'` should be used, it works better.
* Remove bash completion from gce.md
Bash completion instructions do not belong to this guide. (ref: #3476)

* Update kubectl installation instructions on gce.md

This topic is not yet important enough to list exhaustively on /docs/reference.
Also the links are broken anyway. Fixes#3535.
