 I wouldn't use the terrafrom modules from internet.
 The goal is to create all cloud services from scratch.

+## Common
+
+* **cilium** network with vxlan tunnels.
+* **ingress-nginx** (daemonsets) runs on ```web``` role nodes.
+It uses ```hostNetwork``` ports 80,443 for optimizations.
+It helps me to tweak the kernel on a host and apply it to ingress controller.
+And I can disable conntrack too.
+* **coredns-local** (daemonsets) uses dummy interface on al nodes and has ip ```169.254.2.53```
+It increases the dns response (all traffic does not leave the node).
+It makes sense in multi-cloud setup. Kubernets still does not have geo-based load balancer capabilities (alfa).
+* **rancher.io/local-path** as default storage class.
