From 24a1654c1d24b0d5d89156682807312e0e334164 Mon Sep 17 00:00:00 2001 From: dcabib Date: Tue, 7 Oct 2025 08:37:02 -0300 Subject: [PATCH 1/3] feat: Add nested stack changeset support to sam deploy Fixes #2406 Enables visibility into nested stack changes during sam deploy changesets. Users can now see what resources will be created/modified in nested stacks before deployment without checking the CloudFormation console. Changes: - Enable IncludeNestedStacks parameter in changeset creation - Add recursive nested stack changeset traversal and display - Enhance error messages for nested stack failures - Add [Nested Stack: name] headers to indicate nested changes - Maintain backward compatibility with non-nested stacks Testing: - 7 new unit tests for nested changeset functionality - All 67 deployer tests passing - Production deployment verified - 94.21% code coverage maintained --- samcli/lib/deploy/deployer.py | 169 +++++++++++-- tests/unit/lib/deploy/test_deployer.py | 40 ++-- .../lib/deploy/test_deployer_nested_stacks.py | 222 ++++++++++++++++++ 3 files changed, 383 insertions(+), 48 deletions(-) create mode 100644 tests/unit/lib/deploy/test_deployer_nested_stacks.py diff --git a/samcli/lib/deploy/deployer.py b/samcli/lib/deploy/deployer.py index b4368b27ec..0d235111f4 100644 --- a/samcli/lib/deploy/deployer.py +++ b/samcli/lib/deploy/deployer.py @@ -17,11 +17,12 @@ import logging import math +import re import sys import time from collections import OrderedDict, deque from datetime import datetime -from typing import Dict, List, Optional +from typing import Dict, List, Optional, Union import botocore @@ -183,6 +184,7 @@ def create_changeset( "Parameters": parameter_values, "Description": "Created by SAM CLI at {0} UTC".format(datetime.utcnow().isoformat()), "Tags": tags, + "IncludeNestedStacks": True, } kwargs = self._process_kwargs(kwargs, s3_uploader, capabilities, role_arn, notification_arns) @@ -243,27 +245,73 @@ def describe_changeset(self, change_set_id, stack_name, **kwargs): :param kwargs: Other arguments to pass to pprint_columns() :return: dictionary of changes described in the changeset.
