Detailed design

For all beta clusters

# variables.tf
variable "gcs_fuse_csi_driver" {
  type        = bool
  description = "The status of the GCSFuse CSI driver addon, which allows the usage of a gcs bucket as volumes."
  default     = false
}

# cluster.tf
resource "google_container_cluster" "primary" {
# ...
  addons_config {
    # ...
    gcs_fuse_csi_driver_config {
      enabled = var.gcs_fuse_csi_driver
    }
    # ...
  }
}
