"Whether you project needs that or not is something you should definitely explore in depth before you set out and try to use it." Unfortunately, as someone who's written these kinds of orchestrators a few times already (going back to jails on FreeBSD 4.8 and Xen domUs on NetBSD 2.0) and has a nose for where they're a good idea, I find this is overwhelmingly not the prevailing wisdom. I desperately wish it were.

Somewhere, the industry went all-in on Kubernetes, and I have zero desire to touch most of the resulting software stacks. We sold folks hard on complexity being necessary, and Kubernetes makes it very tempting to go ham with it.
