Enable kube-proxy metrics and allow Prometheus scrapes * Configure kube-proxy --metrics-bind-address=0.0.0.0 (default 127.0.0.1) to serve metrics on 0.0.0.0:10249 * Add firewall rules to allow Prometheus (resides on a worker) to scrape kube-proxy service endpoints on controllers or workers * Add a clusterIP: None service for kube-proxy endpoint discovery 2019-12-29 21:21:49 +01:00			`# Allow Prometheus to scrape service endpoints`
addons: Add better alerting rules to Prometheus manifests * Adapt the coreos/prometheus-operator alerting rules for Typhoon, https://github.com/coreos/prometheus-operator/tree/master/contrib/kube-prometheus/manifests * Add controller manager and scheduler shim services to let prometheus discover them via service endpoints * Fix several alert rules to use service endpoint discovery * A few rules still don't do much, but they default to green 2017-11-08 10:35:56 +01:00			`apiVersion: v1`
