In time there will probably be mature build tools to compile unikernels from application sources. Instead of running maven or gradle to output a jar, you'll output a unikernel VM image. Containers complicate things because they add an extra layer onto a host OS. With unikernels there will be a layer removed, the host OS itself. You'll still need tools to manage and orchestrate the VMs running the unikernels, but I think things will get simpler, not more complicated.
