Got started on this using the community kube-prometheus-stack, but still need to:

• Add alerting channel (email or slack or something)
• Configure more than the default dashboards
  • May need to separate out grafana to import more community dashboards

Alerting is working via slack. Still need to fix Flux slack notifications and GitHub status updates.
