Example 1
===============================
Maps are a way to create variables that are lookup tables. An example will show this best. Let's extract our AMIs into a map and add support for the us-west-2 region as well:

variable "amis" {
  type = "map"
  default = {
    "us-east-1" = "ami-b374d5a5"
    "us-west-2" = "ami-4b32be2b"
  }

Diving into Kubernetes MutatingAdmissionWebhook

Admission controllers are powerful tools for intercepting requests to the Kubernetes API server prior to persistence of the object. However, they are not very flexible due to the requirement that they are compiled into binary into kube-apiserver and configured by the cluster administrator. Starting in Kubernetes 1.7, Initializers and External Admission Webhooks are introduced to address this limitation. In Kubernetes 1.9, Initializers stays in alpha phase while External Admission Webhooks have been promoted to beta and split into MutatingAdmissionWebhook and [ValidatingAdmissionWebhook](https://kubernetes
