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
