8080 is a pretty common port, using nodelocaldns_ip:8080 still
prevents node processes or hostNetwork=true processes to bind to *:8080
so switch to 9254 by default (prometheus port is 9253)

Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.

* Adapt templates after feedback
* Remove debugging
* Add support for running a nodelocal dns cache
After encountering dns issues in a cluster I was recently working on I
noticed Kubernetes 1.13 introduced support for running a nodelocal dns
cache.
I believe this can usefull for more people.

ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version
remove empty when line
ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version
force kubeadm upgrade due to failure without --force flag
ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version
added nodeSelector to have compatibility with hybrid cluster with win nodes, also fix for download with missing container type
fixes in syntax and LF for newline in files
fix on yamllint check
ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version
some cleanup for innecesary lines
remove conditions for nodeselector
* kubedns & kubedns-autoscaler: Stick to master nodes.
- Tolerate only master nodes and not any NoSchedule taint
- Pods are on different nodes
- Pods are required to be on a master node.
* kubedns: use soft nodeAffinity.
Prefer to be on a master node, don't require.
* coredns: Stick to (different) master nodes.
- Pods are on different nodes
- Pods are preferred to be on a master node.
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

* Fix autoscaler tolerations field
* set all kube resources to state=latest
* Update netchecker and weave
* Adding yaml linter to ci check
* Minor linting fixes from yamllint
* Changing CI to install python pkgs from requirements.txt
- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements
Pod opbject is not reschedulable by kubernetes. It means that if node
with netchecker-server goes down, netchecker-server won't be scheduled
somewhere. This commit changes the type of netchecker-server to
Deployment, so netchecker-server will be scheduled on other nodes in
case of failures.
In kubernetes 1.6 ClusterFirstWithHostNet was added as an option. In
accordance to it kubelet will generate resolv.conf based on own
resolv.conf. However, this doesn't create 'options', thus the proper
solution requires some investigation.
This patch sets the same resolv.conf for kubelet as host

By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.
K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.
This patch also fixes kube-api port in calico-policy-controller
yaml template.
Closes#1132
By default kubedns and dnsmasq scale when installed.
Dnsmasq is no longer a daemonset. It is now a deployment.
Kubedns is no longer a replicationcluster. It is now a deployment.
Minimum replicas is two (to enable rolling updates).
Reduced memory erquirements for dnsmasq and kubedns
Operator can specify any port for kube-api (6443 default) This helps in
case where some pods such as Ingress require 443 exclusively.
Closes: 820
