Kubernetes configs to setup prometheus

Initially aimed at minikube, but should be adaptable for real clusters.

• Adds node_exporter DaemonSet to each node
• Creates a persistant volume and claim for prometheus data
• Creates a prometheus instance
• Creates an alertmanager instance.
• Creates a pushgateway instance.
• Creates a statsd exporter instance.
• Creates a blackbox exporter instance.
• Prometheus will monitor all elements of the kube cluster (including services)
• A grafana deployment (no state is kept yet, and no default data source setup)
• A templated grafana dashboard (not loaded by default yet)

Helm

I'm hoping to turn this into a usable set of helm charts. The current set are installable via helm, but no confguration is provided.

helm install .

TODO

• How to specify the volumes?
• Prometheus rules in a config map
• Reload prometheus config on rule update
• HA Prom (should just mean changing the rep count)
• HA Alertmanager
• Alertmanager config
