Flux + Observability: Featuring Prometheus Operator and Pixie

on YouTube ↗26m

" summary

Flux demonstrates concrete observability plumbing: the Flux notification controller forwards controller events to Slack/GitHub with secrets decrypted via GCP KMS and workload identity; Flux exports Prometheus metrics consumed by kube-prom-stack + Grafana and Alertmanager for rate/latency alerting; a Tailscale subnet router exposes cluster service IPs to a laptop without public ingress; Pixie eBPF agentless traces reveal HTTP call paths. Demo largely works though network hiccups delay some dashboards.
