Not quite. To get started building Unikraft unikernels, you can use kraft[0] tool which builds a bootable image. At the moment, this is the entrypoint into the ecosystem and allows you to build, for example, NGINX for KVM, Xen or bare-metal.

Having said this, we have on-going work to integrate Unikraft into Kubernetes. We are very excited about this work and will be making noise and providing extra details about this very soon :)
