Lite virtualization of processes

Question

I'm trying to figure out (if it is possible) how to run an user process in an insulated context (memory, network and other resources).

Let's assume that the program x is stored into a filesystem of an host machine (h). I would like to execute x in an insulated hosted context (c) (in other words, without creation of virtual hosted OSs).

The process elaborates output files into is context c. Then i would like to use those files into h context.

I heared about LXC, docker, dockerlite, openvz, etc. but it seems that one must create a container starting from an OS image.

So, shortly, is there a way to run x into c and get results (if any) into h?

Using Docker you could create c (a container) and share a directory from the host (h) where you put your results from x. Please see the volume docs on docs.docker.io.

c doesn't need to contain a full OS image. The busybox base container, for example, is about 2.5MB.

My question is: can `x` reside into `h` and be executed on `c`? – Filippo Lauria Feb 28 '14 at 11:17
Yes. Once you share the volume from the host into the container `c` you can execute code `x` if it is on that volume. – Andy Feb 28 '14 at 19:34
