To deploy the entire project, you can add it to the repository, and we will upload it to the virtual machine by copying the installation script to this virtual machine and then launching it:

Moving on to Kubernetes

In the minimal version, creating a cluster of three nodes looks like this:

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

provider "google" {

credentials = "$ {file (" ../ kubernetes_key.json ")}"

project = "node-cluster-243923"

region = "europe-north1"

}

resource "google_container_cluster" "node-ks" {

name = "node-ks"

location = "europe-north1-a"

initial_node_count = 3

}

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