Sounds like a good candidate for qemu/kvm or libvirt+kvm + (ovirt or virtmanager) then I would intall a kubernetes cluster+ docker top of it using kubespray with 5 small nodes something like 2cpu/4GBram and a large master with stacked etcd. As you could imagine this might consume time and requires area of interest, even you can install kubernetes straight, so I would try to script process as much as I could, take snapshot of images that in future you will not need to deal with it anymore. Otherwise when something goes wrong you will be lazy to re-install everything. Actually this is what I am going to do this week.
