By adding variables, which I selected in a separate file just for clarity, which parameterize our config for different uses, we can use it, for example, to create test and production clusters. Variables can be added as var.name_value , and inserted into the text similarly to JS: $ {var.name_value} , as well as path.root .

essh @ kubernetes-master: ~ / node-cluster / Kubernetes $ cat variables.tf

variable "region" {

default = "europe-north1"

}

variable "project_name" {

type = string

default = ""

}

variable "gce_key" {

default = "./kubernetes_key.json"

}

variable "node_count_zone" {

default = 1

}

They can be passed through the -var switch , for example: sudo ./terraform apply -var = "project_name = node-cluster-243923" .

essh @ kubernetes-master: ~ / node-cluster / Kubernetes $ cp ../kubernetes_key.json.

essh @ kubernetes-master: ~ / node-cluster / Kubernetes $ sudo ../terraform apply -var = "project_name = node-cluster-243923"

Our project in the folder is not only a project, but also a module ready to use:

essh @ kubernetes-master: ~ / node-cluster / Kubernetes $ cd ..

essh @ kubernetes-master: ~ / node-cluster $ cat main.tf

module "Kubernetes" {

source = "./Kubernetes"

project_name = "node-cluster-243923"

}

essh @ kubernetes-master: ~ / node-cluster $ sudo ./terraform apply

Or upload to the public repository:

essh @ kubernetes-master: ~ / node-cluster / Kubernetes $ git init
