Summary

This PR extends standalone Module support with a small, typed project configuration surface and applies the resolved settings consistently across build, run, test, install, package, build-container, and run-container.

Project configuration

Standalone Modules can define these settings in [tool.holoscan]:

Setting Purpose
cuda Module-wide CUDA major version
ctest-script Module-relative CTest driver
forward-env Names of host environment variables allowed into project containers
docker-build-args Static Docker build argument tokens
docker-run-args Static Docker run argument tokens
base-images.x86_64 / base-images.aarch64 Exact base image for each supported target architecture

Unknown keys and invalid values are rejected. Machine-specific SDK locations remain runtime choices through --local-sdk-root or HOLOSCAN_SDK_ROOT; there is no SDK path in project configuration.

Resolution behavior

  • Keeps Module identity, minimum SDK version, Dockerfile, applications, and modes in metadata.json.
  • Selects the target architecture from HOLOSCAN_CLI_TARGET_ARCH, then the host architecture.
  • Lets command options and explicit environment variables override project scalar defaults.
  • Composes Docker arguments in this order: project, selected mode, environment, command line. Forwarded environment names are additive across project, environment, and command-line sources.
  • Resolves a local SDK from the command line, HOLOSCAN_SDK_ROOT, the local-build workspace, a nearby SDK checkout, then the installed default. An invalid explicit environment path warns without silently selecting another SDK.
  • Treats tagged and digested base images as exact references; an untagged environment repository is composed with the selected SDK/CUDA tag unless an explicit image format is configured.
  • Reports the effective project, mode, architecture, CUDA, SDK, images, and option sources with --verbose without printing Docker/CMake argument contents or forwarded values.
  • Updates status and system checks to report the selected target architecture and resolved SDK consistently.

Generated Module and compatibility updates

  • Configures generated Modules for direct uv run holoscan ... usage without building the Module as a host Python package.
  • Documents the supported project settings and standalone lifecycle defaults.
  • Uses HOLOSCAN_CLI_CONTAINER_PREFIX for standalone Module image names while preserving wrapper-provided repository prefixes.
  • Raises the supported Python range from 3.10–3.13 to 3.11–3.13 and updates the generated template and CI matrix accordingly.

Validation

  • python -m pytest — 458 passed, 1 skipped
  • Ruff, Black, isort, and diff checks
  • GitHub Code Check on Python 3.11, 3.12, and 3.13
  • HoloHub wrapper integration, wheel/sdist build, installed-artifact smoke, and CPU/Docker smoke tests
  • CodeQL and dependency review

AI-assisted: Created with Codex/GPT at the user's request.

Walkthrough

The CLI now discovers typed project configuration, resolves architecture-aware SDKs, composes Docker and build options, forwards validated environments, redacts displayed values, and reports effective settings. Lifecycle commands and templates now target Python 3.11–3.13.

Changes

Configuration-driven CLI lifecycle

Layer / File(s) Summary
Runtime and template baseline
.github/*, pyproject.toml, README.md, CONTRIBUTING.md, src/holoscan_cli/templates/module/..., src/holoscan_cli/utils/env_info.py, src/holoscan_cli/utils/host_setup.py
Supported Python versions now start at 3.11. CI, templates, environment reporting, host setup, and documentation use the updated runtime and template configuration.
Project context and SDK resolution
src/holoscan_cli/project_context.py, src/holoscan_cli/utils/sdk.py, CONFIGURATION.md, tests/unit/test_project_context.py, tests/unit/test_sdk_utils.py
Project discovery parses and validates Module metadata and [tool.holoscan]. SDK resolution supports architecture-aware installations, build trees, CUDA selection, and explicit-root precedence.
Configuration, argument, and display utilities
src/holoscan_cli/utils/project.py, src/holoscan_cli/utils/text.py, src/holoscan_cli/utils/validators.py, src/holoscan_cli/utils/holohub.py, src/holoscan_cli/utils/io.py, src/holoscan_cli/utils/docker.py, src/holoscan_cli/container/parsers.py
Shared helpers now resolve precedence, normalize shell arguments, validate inputs, merge Docker options, redact displayed values, and report effective configuration.
Container image, resource, and environment behavior
src/holoscan_cli/container/core.py, src/holoscan_cli/utils/docker.py, tests/unit/test_container_core.py, tests/unit/test_container_recursion.py
Container builds and runs compose mode and CLI settings, resolve images and SDK roots, forward allowlisted variables, apply CPU resources, and hide configured command values.
Lifecycle command integration
src/holoscan_cli/cli.py, src/holoscan_cli/commands/*, src/holoscan_cli/commands/registry.py, src/holoscan_cli/status.py, src/holoscan_cli/system_check.py, tests/unit/test_*
Build, run, test, install, and package commands use shared configuration and container behavior. Status and system checks use the new SDK discovery and project naming rules. Tests cover argument separation, recursion, reporting, SDK selection, CPU handling, and template output.

Estimated code review effort: 5 (Critical) | ~90+ minutes

Merge Risk: 🟡 Moderate · up to cc340

This PR changes project and container configuration resolution across the standalone Module lifecycle, but the current implementation can pair an explicitly selected CUDA version with a different SDK, causing builds to use inconsistent toolchains. Additional bounded issues may produce confusing configuration failures, incorrect cleanup behavior, or environment-dependent test results, so the PR needs owner follow-up before merge.

517-528: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Classify recoverable metadata errors by type, not by message text.

The recovery branch decides whether an error is a metadata.json problem by testing whether the metadata path appears in the formatted message. Any future message that includes the Module root path, or a reworded metadata message, silently changes the behavior: a project-configuration error becomes a warning, or a metadata error becomes fatal. A dedicated exception subclass (for example ModuleMetadataError(ProjectContextError)) raised by _read_module_metadata, _module_identity, and the module.dockerfile validation makes the classification explicit.

Rename the comprehension variable to avoid shadowing the path parameter.

Line 246 binds path inside the generator expression while path is also the function parameter. The generator has its own scope, so behavior is correct, but the duplicate name makes the resolution order hard to read.

♻️ Proposed change
-        candidates.extend(sorted(path for path in root.glob(f"{prefix}-*") if path.is_dir()))
+        candidates.extend(sorted(entry for entry in root.glob(f"{prefix}-*") if entry.is_dir()))

Update the stale comment above this call.

The preceding comment states that test only takes container_build because it never forwards docker run flags. This call now passes container_run, so the comment contradicts the code.

-    # test only takes container_build because it never forwards docker run flags).

These assertions do not exercise the default-run-args stripping.

The test sets cli.container.DEFAULT_DOCKER_RUN_ARGS, but RecordingContainer.compose_run_args ignores that attribute and only joins mode_docker_opts and docker_opts. So --network host and --name/--detach never reach _transient_builder_docker_opts, and those not in assertions pass trivially. To cover the filter, include the default fragments in the value returned by the fake compose_run_args.

Inline comments:
In `@CONFIGURATION.md`:
- Around line 23-25: Update the Local SDK resolution documentation to state that
an invalid or non-absolute HOLOSCAN_SDK_ROOT emits a warning and leaves sdk_root
unset rather than falling through to other SDK candidates. Also document the
/workspace/holoscan-sdk probe performed by _resolve_project_profile when
HOLOSCAN_CLI_BUILD_LOCAL is truthy.

In `@src/holoscan_cli/container/core.py`:
- Around line 1027-1040: Update compose_forward_env’s invalid environment-name
fatal message to identify the actual configuration layer that supplied the name,
covering project tool.holoscan.forward-env, HOLOSCAN_CLI_FORWARD_ENV, and the
command-line forward_env argument; otherwise use source-neutral wording instead
of always blaming HOLOSCAN_CLI_FORWARD_ENV.

In `@src/holoscan_cli/utils/project.py`:
- Around line 32-42: Update the build-type resolution around the value selected
from build_type or CMAKE_BUILD_TYPE so blank or whitespace-only values are
treated as unset and return the default build type, while preserving validation
for nonblank unsupported values.

In `@src/holoscan_cli/utils/sdk.py`:
- Around line 252-276: Update resolve_local_sdk_dir to pass
target_arch=source_environment.get("HOLOSCAN_CLI_TARGET_ARCH") when calling
find_hsdk_build_rel_dir, ensuring the composed mode environment controls SDK
architecture selection.

In `@src/holoscan_cli/utils/text.py`:
- Around line 196-231: Update redact_cli_option_values to detect and redact an
assignment-form argv element beginning with assignment_prefix before calling
shlex.split, replacing the entire value—including embedded unquoted spaces—with
replacement. Preserve token-based handling for other argv elements and continue
returning the existing fallback for malformed shell input.
- Around line 146-155: Update normalize_args_str to catch ValueError from
shlex.split for malformed shell fragments and convert it into a CLI error using
the existing fatal utility, preserving normal token expansion and joining for
valid input.

In `@tests/unit/test_cli_behaviors.py`:
- Around line 171-185: Update
test_metadata_docker_argument_arrays_preserve_shell_fragments to replace the
hard-coded /tmp/module cache path with a non-/tmp path or a tmp_path-derived
value, updating the expected normalized argument accordingly so Ruff S108 passes
while preserving the shell-fragment behavior.

Forward CPU identifiers for local Unix Docker sockets.

Line 104 treats DOCKER_HOST=unix:///... as remote. Docker still uses a local daemon in this case. Both build() and run() then omit the detected CPU limit. Treat Unix socket endpoints, and the default context, as local. Add regression cases for both settings.

Proposed fix
 def _uses_local_docker_cpu_ids(for_build: bool = False) -> bool:
-    if os.environ.get("DOCKER_HOST") or os.environ.get("DOCKER_CONTEXT"):
+    docker_host = os.environ.get("DOCKER_HOST")
+    docker_context = os.environ.get("DOCKER_CONTEXT")
+    if docker_host and not docker_host.startswith("unix://"):
+        return False
+    if docker_context and docker_context != "default":
         return False
     return not for_build or not os.environ.get("BUILDX_BUILDER")

Type-check base-images before indexing it.

base_images is used with in and then with [arch] without a dict check. Every other key in this function validates its value type first. If a user writes a string that contains the architecture name, for example base-images = "nvcr.io/foo:x86_64", then arch not in base_images is False and base_images[arch] raises TypeError: string indices must be integers. The user sees a traceback instead of a ProjectContextError.

🛠️ Proposed fix
     base_images = config.get("base-images")
     if base_images is not None:
+        if not isinstance(base_images, dict):
+            raise ProjectContextError(
+                f"{config_source}: tool.holoscan.base-images must be a table keyed by "

Pass the effective CUDA value into local SDK resolution.

apply_container_cli_overrides stores --cuda in container.cuda_version, but this call does not pass that value to resolve_local_sdk_dir. The resolver uses only the process environment and project context. If an explicit SDK root contains both build-cu12-* and build-cu13-*, --cuda 12 can select one SDK while the container build emits CUDA_MAJOR=12 for the other SDK. Extend the resolver contract with the invocation CUDA value and add a regression test.

Handle template parsing errors with fatal.

When a configured image format reaches _format_image_template, string.Formatter().parse(template) runs before the try block. A malformed template such as repo:{sdk_version raises ValueError and bypasses fatal. Move parsing into the try block with formatting.

Reassert --rm after raw Docker options.

When persistent=False, get_conditional_options(False, persistent) adds --rm before extra_run_args. Docker uses the last value for repeated boolean flags, so a later --rm=false can disable automatic cleanup. Append --rm after extra_run_args, while retaining --rm=false for persistent runs.
