Concerns: Base image tag python:3.14-slim appears invalid/not available in the official registry; should be a valid tag like python:3.11-slim or python:3.12-slim., The Dockerfile installs build-time tooling and then runs 'pip install .', but it does not guarantee that runtime test dependencies (e.g., pytest) are installed; 'CMD pytest' could fail if pytest is not a runtime dependency., COPY . . may copy files not intended for the runtime image (e.g., tests or local configs) depending on repository structure; could be optimized by only copying necessary files.

- Key build step failed: Failing step 6/6 RUN pip install .
- Exact error excerpt (preserved):
Getting requirements to build wheel: finished with status 'error'
× Getting requirements to build wheel did not run successfully.
tracebacks...
LookupError: setuptools-scm was unable to detect version for /src.

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

Alternatively, set the version with the environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME} as described in https://setuptools-scm.readthedocs.io/en/latest/config/

25 |
26 | # Default command: run pytest
- ERROR: failed to build: failed to solve: process "/bin/sh -c pip install ." did not complete successfully: exit code: 1

- What happened:
- The build attempted to install the package from source (pip install .) and failed during “Getting requirements to build wheel” with exit code 1.
- Root cause reported: setuptools-scm could not detect a version for /src; not caused by a missing file or network issue.

- Missing packages/files mentioned:
- None explicitly cited as missing; error centers on version inference by setuptools-scm for /src.

- Version/build-system notes:
- Base image used: python:3.12-slim.
- The log shows a large apt-get install step that pulled in Python 3.13-related packages (e.g., python3.13, python3.13-dev), suggesting a mismatch between the interpreter (3.12 from the image) and newer Python components; this may contribute to environment inconsistencies, though the error is specifically about version inference by setuptools-scm.

Actionable next steps:
- Ensure version metadata is available for the source being built (setuptools-scm expects a git repo with metadata or a tarball from PyPI). Options:
- Build from a fully intact git repository (with .git folder) or from a PyPI tarball.
- If you must build from a source checkout without .git, provide a version via environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME}.
- Confirm/adjust project source availability:
- If using pip to install from VCS, use a proper URL (for example, git+https://github.com/user/proj.git#egg=proj) instead of archive URLs.
- Improve Docker build context:
- Add a proper .dockerignore to avoid shipping large or sensitive files.
- Verify runtime dependencies:
- If the default CMD runs pytest, ensure pytest is listed as a runtime dependency.
- Check base image vs Python components:
- The log’s Python 3.13 components while using python:3.12-slim could indicate environment mismatch—align Python versions or avoid pulling newer components that aren’t needed.
- Re-run after addressing the version inference or metadata issue to confirm the wheel can be built successfully.

This repository uses setuptools_scm for versioning. To build a wheel from source inside a Docker container, make sure to provide git metadata or set a pretend version via environment variable. The recommended approach is to pass an explicit version during build or mount a git repo with .git directory.

Concerns: Default CMD runs pytest which may be inappropriate for a library runtime image; container startup could fail or perform unnecessary work if tests are not intended to run on deployment., Installing build tools and git increases image size and surface area; consider separating build-time dependencies or using multi-stage builds.

  Output: ERROR: /src/pyproject.toml: 'minversion' requires pytest-2.0, actual pytest-0.1.dev1+g9323dbfc7'


Smoke [PASS]: python -V

thoughtI will adjust the Dockerfile to use a valid base image tag (3.12-slim), add a build-arg to provide a pretend version for setuptools_scm, and set the corresponding environment variable to allow building without Git metadata. Then I'll re-run the build verification.

VerifyBuildrejected

Concerns: Final stage attempts to install pytest from /wheel using 'pip install --no-index --find-links=/wheel pytest', but /wheel only contains the library wheel built in the builder stage. There is likely no pytest wheel in /wheel, causing the image build to fail., The library itself is not installed in the final runtime image (the wheel is copied but not installed as the library), and the default CMD runs pytest. If the library isn't installed, pytest won't be able to exercise the library code., Having the default CMD as pytest assumes tests exist in the image; if there are no tests included in the wheel, the container will start and immediately exit, which is not a useful smoke test., Overall, the Dockerfile appears misconfigured for a Python library smoke test because it installs pytest from a local wheel directory that only contains the library wheel rather than pytest.

VerifyBuildunknown

- Build status: build_failed

- Concerns
- Smoke test relies on pytest at runtime (pytest --version); missing test dependencies as runtime dependencies may cause failure after build.
- COPY pyproject.toml ./ and COPY src/ ./src require those paths to exist in the build context; if missing, the build will fail.
- Building from source via pip install . depends on the project’s build backend (PEP 517/518); if pyproject.toml isn’t configured for the build, installation could fail in some environments.

- Build error
- Exit code: 1
- Error: LookupError: setuptools-scm was unable to detect version for /workspace.
- Must build from a fully intact git repository or PyPI tarballs; sources like GitHub tarballs or a git checkout without .git metadata won’t work.
- Example: use git+https://github.com/user/proj.git#egg=proj instead of a zip from GitHub.
- Alternatively, set the version via environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME} as described in setuptools-scm docs.
- Note: error originates from a subprocess; likely not a pip issue.

- Failing command/step
- Step: RUN pip install --no-cache-dir .
- Dockerfile line: 29

- Missing packages or files mentioned
- Missing version metadata for /workspace; build context is not a git repository (lacks VCS metadata/.git), i.e., missing SCM metadata.

- Version mismatch / actionable fixes
- Root cause: setuptools-scm cannot detect a version for /workspace (not a library version mismatch).
- Fixes:
- Build from a fully intact git repository (with .git) or from a PyPI tarball.
- If building from non-repo source, supply a version via environment variable (e.g., SETUPTOOLS_SCM_PRETEND_VERSION_FOR_<NAME>).
- Ensure the build context includes proper version metadata.

▸Build error

- Failing command/step: RUN pip install --no-cache-dir . (step 7/7)

- Exit code: 1

- Exact error message and context:
  - ERROR: Failed to build 'file:///workspace' when getting requirements to build wheel
  - Traceback leads to: LookupError: setuptools-scm was unable to detect version for /workspace.
  - Then guidance:
    Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
    For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj
    Alternatively, set the version with the environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME} as described in https://setuptools-scm.readthedocs.io/en/latest/config/

- Missing packages/files mentioned:
  - Absence of VCS metadata (.git) in the build context /workspace; setuptools-scm cannot infer a version without git or tarball metadata.

- Version mismatch information:
  - Not a package version mismatch per se; this is a metadata/version detection failure from setuptools-scm due to building from a local context that lacks proper VCS metadata.

Concerns: The smoke test in CMD uses pytest --version, which will only succeed if pytest is installed as a runtime dependency. If the library package doesn't include pytest at runtime, this may fail when container is run., COPY pyproject.toml ./ and COPY src/ ./src/ assume these paths exist in the build context; if they are missing or the project layout differs, the build will fail., Optional: Consider removing or guarding the pytest smoke test with a fallback, or explicitly installing pytest as a test/runtime dependency to ensure the smoke test always runs.
Smoke [PASS]: pytest --version
