Deploying Prometheus & Grafana for Cilium

This is an example deployment that includes Prometheus and Grafana in a single deployment.

The default installation contains:

Grafana: A visualization dashboard with Cilium Dashboard pre-loaded.
Prometheus: a time series database and monitoring system.

Enable Metrics in Cilium & Cilium-operator

Enable prometheus metrics on all Cilium agents, be aware this will open the port 9962 in all nodes of your cluster where a cilium-agent is running.

$ kubectl patch -n kube-system configmap cilium-config --type merge --patch '{"data":{"prometheus-serve-addr":":9962"}}'
configmap/cilium-config patched

Make sure you restart all Cilium agents so they can get the new ConfigMap with prometheus-serve-addr option set.

Next, install all monitoring tools and configurations by running:

$ kubectl create -f examples/kubernetes/addons/prometheus/monitoring-example.yaml
namespace/monitoring created
configmap/prometheus created
deployment.apps/prometheus created
service/prometheus created
service/prometheus-open created
clusterrolebinding.rbac.authorization.k8s.io/prometheus created
clusterrole.rbac.authorization.k8s.io/prometheus created
serviceaccount/prometheus-k8s created
configmap/grafana-config created
deployment.apps/grafana created
service/grafana created
configmap/grafana-dashboards created
job.batch/grafana-dashboards-import created
