As you see, amq_detection_component included in the image requires liblog4cxx.so.10 and libapr-1.so.0 -- both not included in the image.

You're right. Those libs are missing from the executor image. This has not been a problem for us since they do end up getting pulled into the C++ component images that need them. For example:

We developed a utility that gets executed as part of the build process that pulls in the transitive dependencies for the C++ components.
