Okay...... I don't believe you had mentioned anything about docker in 
this context up until now...., so perhaps you can understand my original 
confusion...?

As for the rest of that above...  I don't use or know anything about 
Docker, and can't imagine wanting to go through that much hassle for 
some "benefit" that it would gain me...

I'll add this to my list of YARNTWTUD.  (Yet another reason not to want 
to use Docker).  :-)
