Terraform Google Cloud Storage Module

This module makes it easy to create one or more GCS buckets, and assign basic permissions on them to arbitrary users.

The resources/services/activations/deletions that this module will create/trigger are:

  • One or more GCS buckets
  • Zero or more IAM bindings for those buckets

If you only wish to create a single bucket, consider using the simple bucket submodule instead.

Compatibility

This module is meant for use with Terraform 0.12. If you haven't upgraded and need a Terraform 0.11.x-compatible version of this module, the last released version intended for Terraform 0.11.x is 0.1.0.

Usage

Basic usage of this module is as follows:

module "gcs_buckets" {
  source  = "terraform-google-modules/cloud-storage/google"
  version = "~> 1.7"
  project_id  = "<PROJECT ID>"
  names = ["first", "second"]
  prefix = "my-unique-prefix"
  set_admin_roles = true
  admins = ["group:foo-admins@example.com"]
  versioning = {
    first = true
  }
  bucket_admins = {
    second = "user:spam@example.com,eggs@example.com"
  }
  cors = {
    "first" = {
      origin          = ["*"]
      method          = ["GET"]
      response_header = ["*"]
      max_age_seconds = 3600
    }
  }
}

Functional examples are included in the examples directory.
