+  Provides a list of available Google Compute zones

+
+# google\_compute\_zones
+
+Provides access to available Google Compute zones in a region for a given project.
+See more about [regions and zones](https://cloud.google.com/compute/docs/regions-zones/regions-zones) in the upstream docs.
+
+```

+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` (Optional) - Region from which to list available zones. Defaults to region declared in the provider.
+* `status` (Optional) - Allows to filter list of zones based on their current status. Status can be either `UP` or `DOWN`.
+  Defaults to no filtering (all available zones - both `UP` and `DOWN`).
+
+## Attributes Reference
+
+The following attribute is exported:
+
+* `names` - A list of zones available in the given region
