No, this is fundamentally different from docker.

Docker/cgroups/namespaces allow you to isolate multiple applications running in userspace on the same kernel to a very high degree.

This gets rid of isolation and multiprocessing altogether and runs a single application without any kernel at all (i.e. with just a very limited amount of support code linked in).

Put simply; the technology behind docker improves isolation between processes and this does the exact opposite.
