* Fix DNS loop when resolvconf_mode is set to host_resolvconf
* Make sure upstream_dns_servers is defined when using resolvconf_mode == 'host_resolvconf'
* Only set upstream dns servers on KubeDNS and CoreDNS if they are defined
* Only set upstream dns servers on KubeDNS and CoreDNS if they are defined
- Local Volume StorageClass configuration is now manged by `local_volume_provisioner_storage_classes`, a list of maps that specifies local storage classes with `name` `host_dir` and `mount_dir` keys per entry
- Tasks and templates updated to loop through local volume storage classes
- Previous defaults for path/class names were not changed
- Fixed an issue where a `kubernetes/preinstall` was creating directories inconsistently with the `kubernetes-apps/external_provisioner/local_volume_provisioner` task
According to the documentation, container images are described
by vars like `foo_image_repo` and `foo_image_tag`.
The variables netcheck_{agent,server}_{img_repo,tag} do not
follow that convention.

* Created new priorityclass k8s-cluster-critical
* Fixed the trailing spaces
* Fixed the trailing spaces
* Added kube version check while creating Priority Class k8s-cluster-critical

When enable_network_policy is set to True with Calico 3 kubectl
apply fails with the error:
The Deployment "calico-kube-controllers" is invalid:
spec.strategy.rollingUpdate: Forbidden: may not be specified when
strategy type is 'Recreate'
See
https://github.com/kubernetes-incubator/kubespray/issues/3267
Changing the update strategy to RollingUpdate avoids this error.

- 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.

ingress-nginx 0.16.2 (https://github.com/kubernetes/ingress-nginx/releases/tag/nginx-0.16.2)
This patch simplify ingress-nginx deployment by default deploy on
master, with customizable options; on the other hand, remove the
additional Ansible group "kube-ingress" and its k8s node label
injection.
Reference to https://kubernetes.io/docs/concepts/services-networking/ingress/#prerequisites:
GCE/Google Kubernetes Engine deploys an ingress controller on the master.
By changing `ingress_nginx_nodeselector` plus custom k8s node
label, user could customize the DaemonSet deployment target.
If `ingress_nginx_nodeselector` is empty, will deploy DaemonSet on
every k8s node.
- cephfs-provisioner 06fddbe2 (https://github.com/kubernetes-incubator/external-storage/tree/06fddbe2/ceph/cephfs)
Noteable changes from upstream:
- Added storage class parameters to specify a root path within the backing cephfs and, optionally, use deterministic directory and user names (https://github.com/kubernetes-incubator/external-storage/pull/696)
- Support capacity (https://github.com/kubernetes-incubator/external-storage/pull/770)
- Enable metrics server (https://github.com/kubernetes-incubator/external-storage/pull/797)
Other noteable changes:
- Clean up legacy manifests file naming
- Remove legacy manifests, namespace and storageclass before upgrade
- `cephfs_provisioner_monitors` simplified as string
- Default to new deterministic naming
- Add `reclaimPolicy` support in StorageClass
With legacy non-deterministic naming style (where $UUID are generated ramdonly):
- cephfs_provisioner_claim_root: /volumes/kubernetes
- cephfs_provisioner_deterministic_names: false
- Generated CephFS volume: /volumes/kubernetes/kubernetes-dynamic-pvc-$UUID
- Generated CephFS user: kubernetes-dynamic-user-$UUID
With new default deterministic naming style (where $NAMESPACE and $PVC are predictable):
- cephfs_provisioner_claim_root: /volumes
- cephfs_provisioner_deterministic_names: true
- Generated CephFS volume: /volumes/$NAMESPACE/$PVC
- Generated CephFS user: k8s.$NAMESPACE.$PVC
Currently all the gcr.io images used in kubespray can only run on x86.
Also gcr.io has not fully support multi-arch docker images.
Add extra var "image_arch" (default is amd64) to support running other
platforms, like arm64.
Change-Id: I8e1c9af533c021cb96ade291a1ce58773b40e271
Kubespray should not install any helm charts. This is a task
that a user should do on his/her own through ansible or another
tool. It opens the door to wrapping installation of any helm
chart.
The default for kibana_base_url does not make sense an makes kibana unusable. The default path forces a 404 when you try to open kibana in the browser. Not setting kibana_base_url works just fine.
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
