What's a use case for nested containers? A traditional docker setup has you create a container per application. So if I have app x and y, then docker creates two containers. With nested containers would it make sense to have one "host" container that then creates nested containers for apps x and y? What's advantageous about this?

CI builds usually occur within containers. How is one supposed to CI their `Dockerfile` builds inside of such an environment if nesting isn't supported?

It means that my application can work from within a container no differently than outside a container.
