Creating multiple environments with Terraform clusters

When trying to create several clusters from the same configuration, we will encounter duplicate identifiers that must be unique, so we isolate them from each other by creating and placing them in different projects. To manually create a project, go to GCP -> Products -> IAM and administration -> Resource management and create a NodeJS-prod project and switch to the project, wait for its activation. Let's look at the state of the current project:

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

provider "google" {

credentials = file ("./ kubernetes_key.json")

project = "node-cluster-243923"

region = "europe-west2"

}

module "kubernetes" {

source = "./Kubernetes"

}

data "google_client_config" "default" {}

module "Nginx" {

source = "./nodejs"

image = "gcr.io/node-cluster-243923/nodejs_cluster:latest"

endpoint = module.kubernetes.endpoint

access_token = data.google_client_config.default.access_token

cluster_ca_certificate = module.kubernetes.cluster_ca_certificate

}

essh @ kubernetes-master: ~ / node-cluster $ gcloud config list project

[core]

project = node-cluster-243923

Your active configuration is: [default]

essh @ kubernetes-master: ~ / node-cluster $ gcloud config set project node-cluster-243923
