the MAINTAINER Yasset Perez-Riverol <ypriverol@gmail.com> line and add an
equivalent LABEL maintainer="Yasset Perez-Riverol <ypriverol@gmail.com>" entry
instead; ensure the LABEL uses the maintainer key and includes the same name and
email so metadata is preserved.

4-14: LGTM! Comprehensive container metadata.The metadata labels follow best practices and provide comprehensive information about the container. The SPDX license identifier and structured
about.*fields are particularly well done.Optional: Combine LABELs for layer optimization
You could combine all LABEL directives into a single multi-line directive to reduce the number of layers:
-LABEL base_image="python:3.10-slim" -LABEL version="1" -LABEL software="pyspectrafuse" -LABEL software.version="0.0.2" -LABEL about.summary="pyspectrafuse - Command-line utilities for spectrum clustering and conversion" -LABEL about.home="https://github.com/bigbio/pyspectrafuse" -LABEL about.documentation="https://github.com/bigbio/pyspectrafuse" -LABEL about.license_file="https://github.com/bigbio/pyspectrafuse/blob/master/LICENSE" -LABEL about.license="SPDX:Apache-2.0" -LABEL about.tags="Proteomics,Multiomics,QuantMS" +LABEL base_image="python:3.10-slim" \ + version="1" \ + software="pyspectrafuse" \ + software.version="0.0.2" \ + about.summary="pyspectrafuse - Command-line utilities for spectrum clustering and conversion" \ + about.home="https://github.com/bigbio/pyspectrafuse" \ + about.documentation="https://github.com/bigbio/pyspectrafuse" \ + about.license_file="https://github.com/bigbio/pyspectrafuse/blob/master/LICENSE" \ + about.license="SPDX:Apache-2.0" \ + about.tags="Proteomics,Multiomics,QuantMS"This is a minor optimization and the current format is perfectly acceptable.
44-49: Consider non-editable install for production containers.The editable install (
-e) is typically used for development where source code changes should be reflected immediately. For production containers, a regular install is more appropriate since the source code is baked into the image.📦 Recommended change for production
## Install the package -RUN pip install --no-cache-dir -e . +RUN pip install --no-cache-dir .If this container is intended for development purposes, the editable install is fine. Otherwise, consider switching to a non-editable install.
1-50: Consider adding a non-root USER directive.The container currently runs as root, which is a security concern for production deployments. Consider adding a non-root user for running the application.
🔒 Recommended security enhancement
Add these lines before the final installation steps:
## Create non-root user RUN useradd -m -u 1000 pyspectrafuse && \ chown -R pyspectrafuse:pyspectrafuse /data/ USER pyspectrafuseThen adjust the installation steps if needed to ensure the user has appropriate permissions.
Additionally, since the ENTRYPOINT and CMD directives were removed (per PR objectives), please ensure the container usage documentation clearly explains how to run the container and execute pyspectrafuse commands.
Please confirm that documentation has been updated to show users how to run the container without default entrypoints, for example:
docker run pyspectrafuse <command>

Dockerfile (5)
1-2: LGTM! Clear section organization.The section header improves readability and the slim Python image is an appropriate choice for minimizing container size.
19-25: LGTM! Proper container environment configuration.Both environment variables are correctly configured for containerized environments:
DEBIAN_FRONTEND=noninteractiveprevents interactive prompts during package installationNUMBA_DISABLE_CACHING=1avoids caching issues specific to containersThe explanatory comment for NUMBA is particularly helpful for future maintainers.
27-32: LGTM! Follows Docker best practices.The apt-get installation follows Docker best practices:
- Combined into a single RUN command to minimize layers
- Uses
--no-install-recommendsto reduce image size- Cleans up apt lists to further reduce image size
The
procpspackage (which providesps,top, etc.) was added. Please verify this is required for your use case, as it adds to the image size. If it's only needed for debugging, you might consider removing it from production images.
34-35: Document the WORKDIR change.The working directory change from
/appto/data/is a breaking change for users who:
- Mount volumes at
/app- Reference
/appin their container orchestration- Have scripts that assume
/appas the working directoryPlease ensure this change is clearly documented in:
- Release notes or CHANGELOG
- README or container usage documentation
- Any migration guides
This will help users update their container configurations accordingly.
37-42: LGTM! Excellent layer caching strategy.Copying
requirements.txtfirst and installing dependencies before copying application code is a best practice that optimizes Docker's layer caching. The--no-cache-dirflags appropriately reduce the image size.

Replace deprecated MAINTAINER directive.
The MAINTAINER instruction has been deprecated in favor of using LABEL maintainer. While it still works, using the modern syntax aligns with current Docker best practices.
