Attaching the forum problem

I am running make deploy in my dockerfile to construct a c++ application and set up it to a certain folder. Performing an ls in the dockerfile after the code has compiled indicates that the binaries did installation. But when I open a command line inside the picture, the binaries are abruptly missing.

Has all and sundry had this difficulty before? Broadly, what can cause this to happen?

How need to I debug this problem?
