32-bit Apps in a 64-bit Docker Container

Architecture, Docker / / , , , , , , ,

I started my career in December of 1989 at a company named Planning Research Corporation which contracted a considerable amount of work with the Department of Defense. I spent one year working in Fortran 77. The next 6 years were far more interesting to me as I dove into the world of ANSI C programming using the Kernighan & Ritchie bible. I still have my book on a shelf.

Our systems ran on 3 different Unix operating systems. We managed Makefiles that targeted SunOS, DEC Ultrix, and IBM AIX platforms. At times this was quite challenging. However, everything in this environment was 32 bit architecture; but what did that matter to me at the time? 64 bit processors didn’t come along for many more years.
