Ana Fernandez del Alamo a5bbd09776 Support CMEK encryption in logging-bucket module
We have a use case, Local Controls, that requires to configure
CMEK with Logging buckets. This commit adds an optional variable to
configure CMEK in the `logging-bucket` module. By default the Logging
bucket won't use CMEK encryption.

To configure CMEK for Logging buckets it's also required to add the
correct permissions to the bucket service account. For more information
and a Terraform example, see:

Google Cloud Logging Buckets Module

This module manages logging buckets for a project, folder, organization or billing account.

Note that some logging buckets are automatically created for a given folder, project, organization, and billing account cannot be deleted. Creating a resource of this type will acquire and update the resource that already exists at the desired location. These buckets cannot be removed so deleting this resource will remove the bucket config from your terraform state but will leave the logging bucket unchanged. The buckets that are currently automatically created are "_Default" and "_Required".

See also the logging_sinks argument within the project, folder and organization modules.

Examples

Create custom logging bucket in a project

module "bucket" {
  source      = "./fabric/modules/logging-bucket"
  parent_type = "project"
  parent      = var.project_id
  id          = "mybucket"
}
# tftest modules=1 resources=1 inventory=project.yaml

Change retention period of a folder's _Default bucket

module "folder" {
  source = "./fabric/modules/folder"
  parent = "folders/657104291943"
  name   = "my folder"
}

module "bucket-default" {
  source      = "./fabric/modules/logging-bucket"
  parent_type = "folder"
  parent      = module.folder.id
  id          = "_Default"
  retention   = 10
}
# tftest modules=2 resources=2 inventory=retention.yaml

Organization and billing account buckets

module "bucket-organization" {
  source      = "./fabric/modules/logging-bucket"
  parent_type = "organization"
  parent      = "organizations/012345"
  id          = "mybucket"
}

module "bucket-billing-account" {
  source      = "./fabric/modules/logging-bucket"
  parent_type = "billing_account"
  parent      = "012345"
  id          = "mybucket"
}
# tftest modules=2 resources=2 inventory=org-ba.yaml
