DARK

Dashboards As Resources in Kubernetes.

DARK provides a way to define and deploy Grafana dashboards via Kubernetes, next to the services they monitor.

If you are looking for a way to version your dashboards and deploy them across all environments, like you would do with your services, then this project is meant for you.

In addition to dashboards, DARK can also manage:

• data sources
• API keys
• alert manager configuration (alert routing, notification policies, ...)

Design goals

• full description of dashboards via YAML
• integration with kubectl
• seamless integration with Grafana
• delegate YAML decoding and dashboard generation to Grabana

Non-goals

• creation and operation of Grafana instances themselves. For that, check out grafana-operator/grafana-operator
