Monitoring📜
This repository builds on the following upstream chart kube-prometheus-stack
Pre-requisites📜
- Kubernetes cluster deployed
- kubectl configuration installed
- fluxv2 resources and controllers installed
Install kubectl
brew install kubectl
Install flux binary from https://github.com/fluxcd/flux2/releases
Configuration📜
Configuration can be done via editing and supplementing the values for the chart which follows the upstream values for kube-prometheus-stack
You can find the API Spec for the Prometheus Operator here
Grafana📜
By default an admin user with username “admin” and the configured password in the chart at “grafana.adminPassword” is created for logging into the Grafana UI.
Adding Dashboards📜
To supplement the dashboards already provided by the package you can add more dashboards that are automatically loaded into grafana:
Via Helm Values📜
- Ensure dashboardProviders values are populated (uncommented from package values in this case):
monitoring:
values:
grafana:
dashboardProviders:
dashboardproviders.yaml:
apiVersion: 1
providers:
- name: 'default'
orgId: 1
folder: ''
type: file
disableDeletion: false
editable: true
options:
path: /var/lib/grafana/dashboards/default
- Populate dashboard JSON you can name in dashboards block like so:
monitoring:
values:
grafana:
dashboards:
default:
some-dashboard:
json: |
$JSON_DATA$
- Helm reconciliation will mount the JSON data to the grafana pod and restart, if not delete the grafana pod.
Via Configmap📜
- Download the JSON file for your dashboard, or ensure you have the config in JSON formatting.
- Create a secret or configmap like so, where you can include your JSON dashboard configuration inline:
apiVersion: v1
kind: ConfigMap
metadata:
name: my-custom-dashboard
namespace: monitoring
labels:
grafana_dashboard: "1"
data:
dashboard-name.json: |
...
*Any configmap in the monitoring namespace with the “grafana_dashboard” : “#” label will be scanned and imported into grafana automatically. This label can be updated in the helm values: grafana.sidecar.dashboards.label: …
