[Loki & Promtail] Configuration for excluding namespaces from sending logs #72

Closed v-ctiutiu closed 2 years ago

v-ctiutiu commented 2 years ago

Fixes #56

Overview

Added configuration and explanations for excluding logs from specific namespaces (Promtail includes everything by default).
Updated Helm value files (including dependent projects).
Removed unneeded rules from the defaultRules section inside the Prometheus Helm values file.

Nice work. Only issue I see is that we're not excluding the logs from Kube-* by default. But it is a minor thing and can be tackled later just by uncommenting the specific section in the promtail values file.
