I wonder if you've considered building a complete VM image instead of a tarball. A minimal, immutable VM image could be more finely tuned and hardened than a tarball installed on top of a general-purpose distro. You could take inspiration from CoreOS or LinuxKit here. Or do you find that the sysadmins in the kind of organization that install these on-prem packages really want to install on top of their favorite distro?

A minimal immutable VM image which is finely tuned and hardened is the exact approach we're taking with https://on-premises.com https://on-premises.com - except we haven't focused on k8s workloads. We've found that customers would much rather import a VM than "install" something, however there are valid use-cases which require special monitoring tools and other customizations which are not possible on an immutable system. Gravity is interesting and seems to meet that demand.

  This look interesting, is there a way to try out meta without being funneled into the sales pipeline? What is the workflow for baking a machine? Are you using packer under the covers or some other tooling? What on-prem machine image formats are supported?

    There's still a bit of "manual" work to get someone up and running on our Meta appliance, so unfortunately you would have to go through our sales process. However if you just want a video or screen recording of how it works then I can put something online in the next hour or two. For baking the machine, we use Ansible under the covers and have a set of Lisp scripts to manage everything. As for image formats: qcow2, raw, vhd (and vmdk in the .ova file). Not trying to hijack Gravitational's thread, please contact me (email in profile, or 'aw-' on FreeNode) if you want to discuss more.

Actually, some of our customers are doing just that - taking a tarball and making it a VM image. There are a couple of things we are making now to support this use case better, e.g. ability to easily change the ip on the VM boot up.
