I use cgroups, namespaces, and chroots all the time. Daily.  Constantly.
 Right now.  I've only played with docker.

They are single use processes. No shells. No sshd.  No patching.
Limited access to most of the hostOS file system.

Is that a "container"?

I would use containers for internal software development and deployment.
I'm not ready to place them on the internet at this point. If I allowed
php webapps to be internet facing, I'd run each of them in a container
with nothing else, so WHEN they are hacked, there isn't enough of an OS
there to have a shell, no editor, and do anything except run the webapp.
