How to use repo

  1. Create terraform.tfvars file with a few variables
project          = "gcp-project"
region           = "europe-west1"
environment_name = "demo"
  1. Create cluster All commands will be applied via Terraform 1.7.0 and via OpenTofu, the same version.

Here are OpenTofu commands.

tofu init
tofu apply
  1. Get the credentials for the new cluster (configure kubeconfig)

You can see all useful commands and links in the output:

tofu output

There is a manual command:

gcloud container clusters get-credentials $(tofu output -raw kubernetes_cluster_name) --region $(tofu output -raw zone) --project $(tofu output -raw project)

Or just use ./get-credentials.sh

  1. Destroy all resources
tofu destroy
