Do Docker Linux Images Contain Kernels?

Question

If so, wouldn't there be overhead if, say, I install a Debian image which contains a specific version of a Linux Kernel? Now you have a container with a Kernel, on top of another kernel (the docker host's kernel). Or am I missing something?

Or does the docker image have the kernel stripped out some how?

Docker images do not contain kernels, but they could soon. That's why Docker aquired Unikernel not long ago.
