#663 Add support for .flyteignore file Pull request opened by pingsutw ## Summary • Adds support for a custom

.flyteignore

file that works alongside

.gitignore

to exclude files from Flyte code bundles • Modified

GitIgnore

class to explicitly read patterns from both

.gitignore

and

.flyteignore

files using

--exclude-from

flags • Removed reliance on

--exclude-standard

flag for more explicit control over which ignore files are used • Added file existence checks to gracefully handle cases where

.gitignore

or

.flyteignore

don't exist ## Changes • `src/flyte/_code_bundle/_ignore.py`: Updated

_git_wrapper

,

_list_ignored_files

, and

_list_ignored_dirs

methods to check for file existence and use explicit exclude-from flags • `.gitignore`: Added

.flyteignore

to the repository's gitignore • `tests/flyte/code_bundle/test_ignore.py`: Added 3 comprehensive test cases covering: • Combined usage of both

.gitignore

and

.flyteignore

• Directory patterns in both files • Overlapping patterns with negation rules ## Test plan • All existing tests pass • New unit tests added and passing: •

test_gitignore_with_flyteignore

- Tests both files working together •

test_gitignore_flyteignore_directory_patterns

- Tests directory patterns •

test_gitignore_flyteignore_overlapping_patterns

- Tests pattern overlap and negation • Backward compatibility verified - works correctly when

.flyteignore

doesn't exist flyteorg/flyte-sdk
