This Dockerfile and its accompanying files are meant to build a straightforward VMWare WSX server image.
The only thing missing is the bundle that you can download from the VMWare website here, as licensing considerations prevent me from storing it here.
Build the image is done using the usual
$ cd docker-wsx
$ docker build -t [wsx_image] .
Then running it like this:
$docker run -t wsx_server wsx_image
The default listing port is 8888.
