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.
This module is meant for use with Terraform 0.13+ and tested using Terraform 1.0+. If you find incompatibilities using Terraform >=0.13, please open an issue. If you haven't upgraded and need a Terraform 0.12.x-compatible version of this module, the last released version intended for Terraform 0.12.x is v1.7.1.
Basic usage of this module is as follows:
module "gcs_buckets" {
source = "terraform-google-modules/cloud-storage/google"
version = "~> 2.2"
project_id = "<PROJECT ID>"
names = ["first", "second"]
prefix = "my-unique-prefix"
set_admin_roles = true
admins = ["group:[email protected]"]
versioning = {
first = true
}
bucket_admins = {
second = "user:[email protected],[email protected]"
}
}Functional examples are included in the examples directory.
