I'm very interested in the concept, but found Kata to be hard to get going with.

Last time I looked (a few months ago), the documentation was pretty sparse or outdated. A lot of documentation I found stated something like "we broke that in the new version, you can't actually do that right now", like using it with Docker, which I would much prefer over setting up Kubernetes.

I still think it's an absolutely great thing, but the on onboarding could have been a lot less rocky.

FWIW, I eventually kind of DIYed it with QEMU MicroVM and virtiofs - never did anything with it though.
