That is not accurate: the Linux kernel is intentionally *not* part of
the Docker image, since it's meant to be shared between all container
instances and provide the runtime constructs (cgroups, namespaces, ...)
that Docker relies on.
Instead it is provided by the system running the Docker platform: your
regular GNU/Linux distribution, or for other systems typically a virtual
machine running a minimal system (with at least a Linux kernel, and
often not much more) dedicated to running only Docker.
Thanks
Yann.
