Expose Grafana Locally

Apply:

namespace="prometheus"
cat <<EOF | kubectl -n ${namespace} apply -f - 
apiVersion: v1
kind: Service
metadata:
  name: prometheus-grafana-lb
  namespace: ${namespace}
spec:
  type: LoadBalancer
  ports:
  - name: service
    port: 3000
    protocol: TCP
    targetPort: 3000
  selector:
    app.kubernetes.io/instance: prometheus
    app.kubernetes.io/name: grafana
EOF

This will expose Grafana as http://localhost:3000/
