You have answered my question. There are, roughly, using old
terminology, heavy-weight containers and light-weight containers.
VMware used to offer heavy-weight containers that would run "any" MS Win
application under Linux (presuming the same underlying ISA), but were n
some instances extreme resource hogs. Docker thus seems to be a
light-weight container with strong limitations as to the differences in
the underlying environment and OS structures (again, same ISA --
different ISAs require rather different approaches, including the old
Sun approach on SPARC workstations of having a Sbus IA-32 "coprocessor"
board to run a licensed copy of MS Win).

Using containers is nothing like using a fully virtualized kernel.
It's using cgroups, kernel namespaces, and selinux to isolate
applications within Linux and make them easier to deliver.
So you can't run a windows app natively in docker. You'd have to run
Wine in docker and execute your application that way. It's not a
replacement for virtualizaton.

On a different (albeit related) thread, the recommendation was
made to use Docker to "port" alien applications and environments
(presumably with the ISA and basic machine components used by SL7)
to SL 7. Looking at the Docker documentation and license (license
reproduced below), this seems feasible -- rather than using any VM
for the purpose of running such an application.
How many have tried Docker? Does it work well? For example, will
a legally licensed MS Win application that does not run under
Wine/CrossOver work under Docker under SL 7 the same as it would
under VirtualBox with a full install of say MS Win 8.1 (soon MS
Win 10)? Can one make a Docker application package on the target
host (e.g., SL 7) or does one need first a full install of the
(virtual) base (e.g., DLLs and OS environment structures of the
original host of the application, e.g., MS Win) under which to
"dockerize" (e.g., run MS Win under VirtualBox under SL7,
dockerize a MS Win application, and then run the dockerized
application under SL7 without VirtualBox or any regular VM)?
