Docker image flattening loses USER and ENV directives in clp-package Dockerfile

[coderabbitai]

Problem

In tools/docker-images/clp-package/Dockerfile, the USER and ENV commands are declared in the base stage (lines 13-18) before the image is flattened using FROM scratch and COPY --from=base. This causes their effects to be lost in the final image.

Details

The following directives are currently in the base stage:

• ENV CLP_HOME="/opt/clp"
• ENV PATH="${CLP_HOME}/bin:${PATH}"
• ENV PATH="${CLP_HOME}/sbin:${PATH}"
• ENV PYTHONPATH="${CLP_HOME}/lib/python3/site-packages"
• USER 1000:1000

When the image is flattened with FROM scratch followed by COPY --from=base / /, these directives are not preserved in the final image metadata.

Solution

These directives should be moved to after the COPY --from=base / / command in the final stage to ensure they are present in the resulting image.
