All checks test if this is defined meaning there is no way to undefine it.

Changed from OS_PROJECT_ID to OS_PROJECT_NAME.

While `do` looks cleaner, forcing this extra option in ansible.cfg
seems to be more invasive. It would be better to keep the traditional
approach of `set dummy = ` instead.

Kubernetes makes this namespace automatically, so there is
no need for kubespray to manage it.

This file should only be updated during kubelet upgrade so that
master components are not accidentally restarted first during
preinstall stage.

Labels from role (node-role.k8s.io/node) and labels from inventory are merged into node-labels parameter in kubelet

The ability to create dedicated node for ingress nginx controller
host type network for nginx controller

and add from example https://github.com/kubernetes/ingress-nginx/blob/master/docs/examples/static-ip/nginx-ingress-controller.yaml
terminationGracePeriodSeconds: 60

Added CoreDNS to downloads

Updated with labels. Should now work without RBAC too

Fix DNS settings on hosts

Rename CoreDNS service from kube-dns to coredns

Add rotate based on http://edgeofsanity.net/rant/2017/12/20/systemd-resolved-is-broken.html

Updated docs with CoreDNS info

Added labels and fixed minor settings from official yaml file: https://github.com/kubernetes/kubernetes/blob/release-1.9/cluster/addons/dns/coredns.yaml.sed

Added a secondary deployment and secondary service ip. This is to mitigate dns timeouts and create high resitency for failures. See discussion at 'https://github.com/coreos/coreos-kubernetes/issues/641#issuecomment-281174806'

Set dns list correct. Thanks to @whereismyjetpack

Only download KubeDNS or CoreDNS if selected

Move dns cleanup to its own file and import tasks based on dns mode

Fix install of KubeDNS when dnsmask_kubedns mode is selected

Add new dns option coredns_dual for dual stack deployment. Added variable to configure replicas deployed. Updated docs for dual stack deployment. Removed rotate option in resolv.conf.

Run DNS manifests for CoreDNS and KubeDNS

Set skydns servers on dual stack deployment

Use only one template for CoreDNS dual deployment

Set correct cluster ip for the dns server

1. 404 link url
2. kubelet_authentication_token_webhook is not work
3. kube_reserved variable set twice

* allow reset to not restart network (buggy nodes die with this cmd)
* default kube_override_hostname to inventory_hostname instead of ansible_hostname

Support ipvs mode for kube-proxy

import_tasks will consume far less memory, so it should be
used whenever it is compatible.

Fix 'no such host' problem reported by commands *kubectl logs* and *kubectl exec*
when cloud_provider is OpenStack

Closes: #2147

kube-proxy is complaining of missing modules at startup. There is a plan
to also support an LVS implementation of kube-proxy in additon to
userspace and iptables
