Question

A credit-union batch image must always start the same scanner binary, but testers want to override only the folder argument without rebuilding. How should ENTRYPOINT and CMD be assigned?

Accepted Answer

Set ENTRYPOINT to the fixed scanner binary and CMD to the default folder arguments that operators may override — ENTRYPOINT is the locked steering wheel—always the same scanner. CMD is the sticky note with the default folder that testers can swap at run time without baking a new image for every path.

Answer

Put the folder path in ENTRYPOINT and leave CMD empty so arguments can never change at run time

Answer

Use only WORKDIR for the binary path and rely on EXPOSE to supply folder arguments

Answer

Bake every folder variant into separate images so ENTRYPOINT and CMD never need to differ
