That worked perfectly.
And it's a bit odd, because I had that exact contents, but with the "a2enmod rewrite" line after the exif line. And I did have a trailing \ as well.
I'll update my post.
One last question, if you know..... where is the phpi.in file located within this container?
I'd like to setup some "disable_functions" and increase a few of the default parameters like post_max_size and upoad_max_filesize, but am running into a dead end.
In my software, phpinfo shows a lot of directories/folders that simply don't exist on disk when viewed with command-line SSH.
This isn't a "must do", just something I'd prefer to do.
