Code Review

This pull request introduces automated local development environment setup and cleanup through new Makefile targets and bash scripts. The scripts handle Kind cluster creation, namespace setup, local caching, Docling service management, and LocalStack resource configuration. Feedback was provided to improve the scripts' robustness by adding dependency checks, using relative paths for configuration files, removing unused variables, and ensuring the cleanup process removes the local cache directory.

The variable OUTPUT_RESULT_BUCKET is defined but not used anywhere in the script. If this bucket is intended to be part of the local setup, it should be included in the creation loop at line 71. Otherwise, it should be removed to maintain code clarity.

The script relies on several external tools (kind, kubectl, awslocal, curl). It is recommended to verify their presence at the beginning of the script to provide a clear error message to the user instead of failing later with a 'command not found' error.

Suggested change

	echo "Note: Make sure LocalStack is running in a separate terminal:"
	# Check dependencies
	for cmd in kind kubectl awslocal curl; do
	if ! command -v "$cmd" &> /dev/null; then
	echo "Error: $cmd is not installed. Please install it to continue." >&2
	exit 1
	fi
	done
	echo "Note: Make sure LocalStack is running in a separate terminal:"

The path to the notification configuration file is relative to the current working directory. This makes the script fragile if executed from a directory other than the project root. Using a path relative to the script's location is more robust.

Suggested change

	--notification-configuration file://test/resources/unstructured/notification.json
	--notification-configuration "file://$(dirname "$0")/../test/resources/unstructured/notification.json"

The cleanup script should also remove the local cache directory created by the setup script to ensure a complete teardown of the development environment.

Suggested change

	kind delete cluster --name "${LOCAL_KIND_CLUSTER}" 2>/dev/null || true
	kind delete cluster --name "${LOCAL_KIND_CLUSTER}" 2>/dev/null || true
	# Remove local cache
	rm -rf tmp/cache
