Kubernetes controller that watches dashboard configurations defined as configmaps and adds/updates/deletes them to/from grafana

• Access to the Kubernetes API is expected to be granted by the local kubeconfig file.
• You can use equality-based labelSelectors to select the configmaps to watch for dashboard descriptions.
• The controller requires access to the Grafana API, either using an api key or basic auth

Configuration

Configuration can be specified in 2 ways:

• using command line arguments (use --help to see the complete usage instructions)
• using environment variables:

Env Variable		Description	Default	Example
CONFIGMAP_SELECTOR	optional	kube-api compatible labelSelector	""	"role=grafana-dashboard,app=awesome-app"
GRAFANA_API_URL	required	Grafana's api base URL	null	http://grafana.monitoring.svc.cluster.local/api/
GRAFANA_API_KEY	required unless using basic auth	Grafana API Key (get one at <YOU-GRAFANA-INSTANCE-URL>/org/apikeys)	null	"eyJrIjoiWlc4VjZaaFlZbWhwdzFiNVlHbXRn....."
GRAFANA_BASIC_AUTH_USERNAME	required if using basic auth	Grafana username	null	"mbenabda"
GRAFANA_BASIC_AUTH_PASSWORD	required if using basic auth	Grafana plain text password	null	"1234"

Caveat

Because grafana API uses title-derived slugs to identify dashboards, and in order not to have to manage state for this controller: once a dashboard is managed, its title must not be changed.

To update a managed dashboard's title:

• delete the corresponding configmap from kubernetes
• change the title in the configmap's dashboard json desciption
• apply the configmap manifest

Run on Docker

docker run \
       -v $HOME/.kube/:/root/.kube:ro \
       mbenabda/k8s-grafana-dashboards-controller:0.1.1 \
       --grafana-url http://grafana:3000 \
       --grafana-user johndoe \
       --grafana-password s3cr3t \
       --selector role=grafana-dashboard
