This is getting off-topic, but I didn't understand the rationale behind that. Processes running inside docker/k8s are already isolated, so unless you're running something potentially malicious, why would it matter if it's root or not?

(Of course, if you're running untrusted user code, then you'll need every protection you can muster, but I'm talking about running an internally developed application. If you can't trust that, you already have a bigger problem.)

Docker won't run on my local machine as non root. And all the stuff I have seen so far has been run as root.
