# Manage Terraform State on Google Cloud Storage(GCS)
It's a best pratice to manage Terraform state on central storage like GCS for GCP.
We need to create a Bucket to store the state files:
$ gsutil mb -p pkslow -l us-west1 -b on gs://pkslow-terraform
Creating gs://pkslow-terraform/...
$ gsutil ls gs://
gs://pkslow-terraform/
Define the backend "gcs" in Terraform code:
terraform {
backend "gcs" {
bucket = "pkslow-terraform"
prefix = "state/gcp/pubsub"
}
}
Initiate the Terraform project, it will help to create folder in the Bucket:
$ terraform init -plugin-dir=${TERRAFORM_PLUGIN}
Apply the change:
$ terraform apply -auto-approve
Check on the GCP Console, the state file is created:
What's more, we can also fetch the data from the remote state:
data "terraform_remote_state" "foo" {
backend = "gcs"
config = {
bucket = "terraform-state"
prefix = "prod"
}
}
resource "template_file" "bar" {
template = "${greeting}"
vars {
greeting = "${data.terraform_remote_state.foo.greeting}"
}
}
