# Google Cloud Artifact Registry Module

This module simplifies the creation of a Binary Authorization policy, attestors and attestor IAM bindings.

## Example

### Binary Athorization

```hcl
module "binauthz" {
  source                        = "./fabric/modules/binauthz"
  project_id                    = "my_project"
  global_policy_evaluation_mode = "DISABLE"
  default_admission_rule = {
    evaluation_mode  = "ALWAYS_DENY"
    enforcement_mode = "ENFORCED_BLOCK_AND_AUDIT_LOG"
    attestors        = null
  }
  cluster_admission_rules = {
    "europe-west1-c.cluster" = {
      evaluation_mode  = "REQUIRE_ATTESTATION"
      enforcement_mode = "ENFORCED_BLOCK_AND_AUDIT_LOG"
      attestors        = ["test"]
    }
  }
  attestors_config = {
