# How to use

1. Create *.tfvars file with a few variables
```
project          = "gcp-project"
region           = "europe-west1"
environment_name = "demo"
```

2. Create cluster
```
terraform init
terraform apply
```

3. Configure kubeconfig for new cluster
```
gcloud container clusters get-credentials $(terraform output -raw kubernetes_cluster_name) --region $(terraform output -raw region) --project $(terraform output -raw project)
```

4. Destroy all resources
```
terraform destroy -target 'kubernetes_namespace.flux-system'
terraform destroy -target 'google_container_node_pool.primary_nodes'
terraform destroy -target 'google_container_cluster.primary'
terraform destroy -target 'google_compute_subnetwork.subnet'
terraform destroy -target 'google_compute_network.vpc'
terraform destroy -target 'data.google_client_config.primary'
```
