Dockerization and Virtualization

An expert posted an excellent response to my last question stating that a Docker is primarily used to have a disk image of the entire OS  in order to contain all of the dependencies within a single image and then it can be transported to an IaaS (or other) environment for deployment

So to my question:  Can Dockerization also be used to virtualize images in a manner simular to VMWare, where the images are assigned a set of cores, differing NIC's, etc

Or is that a separate concept altogether, and Dockerization is simply used to import a clean and complete environment.

No, docker "images" is just a chroot directory with files.

Docker helps you build slim applications using one OS (Kernel), it's the same concept of a hypervisor except this is at the application layer. You won't need a full OS to run your applications and all the extra overhead that comes with that.
