Cluster add-on upgrades, with Loki, Traefik and monitoring refreshed

#add-on  #kubernetes  #update  #upgrade  #component  #eks 

We rolled out another round of cluster add-on upgrades. It is shipping to non-production clusters first, with production to follow in the coming week. Most of it is routine version hygiene, but three charts got a major refresh (Loki, Traefik, and the kube-prometheus-stack monitoring stack), and your oauth2-proxy now reports metrics to your cluster monitoring.

What changed

  • oauth2-proxy metrics are now scraped. A casing typo in our config meant the oauth2-proxy ServiceMonitor was never created, so its metrics were not collected. That is fixed: oauth2-proxy now appears as a Prometheus target and its metrics are available in Grafana.
  • Loki, Traefik and kube-prometheus-stack moved up a major chart version each. These are mostly internal chart changes (Helm value renames, refreshed Prometheus Operator CRDs). The one thing you’ll notice: Loki’s Grafana dashboards now come from the upstream chart, so you’ll see a refreshed set of Loki dashboards, with app_instance as the cluster selector instead of cluster.
