alt Hacker NewsIf the developers can only get it to run in a pile of ubuntu containers, then it's extremely likely they haven't thought through basic things you need to operate a service, like supply chain security, deterministic builds, unit testing, upgrades, etc.
I see 6 officially supported linux distributions. I don't know where anyone got the idea that they can only get it to run on ubuntu. It's containerized. Who cares what the host os is, beyond "it can run containers"?
