+  Provides lists of available platform versions for the Container Attached resources.
+---
+
+# google\_container\_attached\_versions
+
+Provides access to available platform versions in a location for a given project.
+
+## Example Usage
+
+```hcl
+data "google_container_attached_versions" "uswest" {
+  location       = "us-west1"
+  project        = "my-project"
+}
+
+
+output "first_available_version" {
+  value = data.google_container_attached_versions.versions.valid_versions[0]
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `location` (Optional) - The location to list versions for.
+
+* `project` (Optional) - ID of the project to list available platform versions for. Should match the project the cluster will be deployed to.
+  Defaults to the project that the provider is authenticated with.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `valid_versions` - A list of versions available for use with this project and location.
