Description

EventArc eventFilters resource can be configured with matching_criteria field in terraform. This terraform schema supports fields 'attribute' and 'value' only.

Third field 'operator' is also required. This field can be used to implement additional resource filtering, at least with matching path patterns.

New or Affected Resource(s)

• google_eventarc_trigger

Example configuration for the 'operator' field can be defined from cloud console by selecting resource type 'path pattern' in the eventarc trigger 'edit' form.

For a cloud storage bucket the resulting configuration is something like following, as seen in gcloud eventarc triggers describe output after defining pathPattern in web console:

eventFilters:
- attribute: resourceName
  operator: match-path-pattern
  value: /projects/_/buckets/my-bucket-name/objects/*
- attribute: type
  value: google.cloud.audit.log.v1.written
- attribute: serviceName
  value: storage.googleapis.com
- attribute: methodName
  value: storage.objects.create

Potential Terraform Configuration

    matching_criteria {
      attribute = "resourceName"
      operator = "match-path-pattern"
      value = "projects/_/buckets/${var.my_bucket_name}/objects/*"
    }
