1. In About Logging-> Logging architecture (not 6.0), the docs says infrastructure namespaces are

Container logs generated by infrastructure namespaces: openshift*, kube*, or default, as well as journald messages from nodes.

However, we've define infrastructure namespaces as "default", "kube", "openshift", and namespaces prefixed with "kube-" or "openshift-".

2. In the Logging 6.0 input docs, application & infrastructure are defined as such:

application

Selects logs from all application containers, excluding those in infrastructure namespaces such as default, openshift, or any namespace with the kube- or openshift- prefix.

infrastructure

Selects logs from infrastructure components running in default and openshift namespaces and node logs.

This list will need to include "kube" as an infra namespace
