So far, I shall thank Kenneth Wyrick for finding a ]Project-Open[ installation on Docker.
That means, Frank has been working on having PO-OACS on Docker, in a Centos based system.
Now, it'd be just a matter of reviewing his scripts and changing it to work on Debian/Ubuntu Docker installation.
Thank you Kenneth! It saved me some hours (and headaches), elaborating a whole lot of code.
Best wishes,
I
