dynamic-link and no-build targets use a trivial copy all from /opt, leading to unused modules and unused build artifacts to be copied to the resulting IOC image.

Any level of pruning could easily and greatly improve the final image size.

Possible strategies:

  • list of used modules in a docker-compose variable
  • list of used modules taken from original RELEASE file before it's replaced
  • prune directories at the /opt/modules and /opt/modules/areaDetector levels when they don't appear in lddoutput for all executables/libraries in IOC / final directory (for no-build mode)
