From 560ad17aafd103ed336156323dddb72842373055 Mon Sep 17 00:00:00 2001 From: arkhan Date: Tue, 8 Jul 2025 09:49:57 -0500 Subject: [PATCH 1/3] feat: add recursive discovery of compose files up to 10 levels This feature allows podman-compose to locate a compose file (e.g., docker-compose.yml, compose.yml, etc.) when executed from deep within a project structure. If a user runs `podman-compose ps` from a subdirectory like `project/addons/module/component`, the tool will search upward through parent directories (up to 10 levels) to find a compose file located in the root of the project (e.g., `project/`). This improves usability by eliminating the need to manually navigate to the project root or specify the `--file` option. Notes: - Supports common file names like `docker-compose.yml`, `compose.yml` - Max search depth: 10 parent directories --- podman_compose.py | 59 +++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 57 insertions(+), 2 deletions(-) diff --git a/podman_compose.py b/podman_compose.py index c3c44cc0..d499af0a 100755 --- a/podman_compose.py +++ b/podman_compose.py @@ -1975,6 +1975,43 @@ def dotenv_to_dict(dotenv_path: str) -> dict[str, str | None]: ] +def find_compose_files_recursively(start_dir: str, compose_files: list[str], max_depth: int = 10) -> tuple[list[str], str] | None: + """ + Search for compose files recursively up the directory tree. + + Args: + start_dir: Directory to start searching from + compose_files: List of compose file names to search for + max_depth: Maximum depth + + Returns: + A tuple (found_files, base_directory) or None if no files found + """ + current_dir = os.path.abspath(start_dir) + + for depth in range(max_depth): + # Search for compose files in current directory + found_files = [] + for compose_file in compose_files: + file_path = os.path.join(current_dir, compose_file) + if os.path.exists(file_path): + found_files.append(file_path) + + if found_files: + log.debug("Found compose files in %s: %s", current_dir, found_files) + return found_files, current_dir + + parent_dir = os.path.dirname(current_dir) + + # If we've reached the root directory, stop searching + if parent_dir == current_dir: + break + + current_dir = parent_dir + + return None + + class PodmanCompose: class XPodmanSettingKey(Enum): DOCKER_COMPOSE_COMPAT = "docker_compose_compat" @@ -2169,13 +2206,31 @@ def _parse_compose_file(self) -> None: if project_dir and os.path.isdir(project_dir): os.chdir(project_dir) pathsep = os.environ.get("COMPOSE_PATH_SEPARATOR", os.pathsep) + if not args.file: default_str = os.environ.get("COMPOSE_FILE") if default_str: default_ls = default_str.split(pathsep) + args.file = list(filter(os.path.exists, default_ls)) else: -
