• Grafana
• GrafanaDashboard

Building the operator image

Init the submodules first to obtain grafonnet:

$ git submodule update --init

Then build the image using the operatpr-sdk:

$ operator-sdk build <registry>/<user>/grafana-operator:<tag>

Running locally

You can run the Operator locally against a remote namespace using the operator-sdk:

Prerequisites:

• operator-sdk installed
• kubectl pointing to the local context. minikube automatically sets the context to the local VM. If not you can use kubectl config use <context> or (if using the OpenShift CLI) oc login -u <user> <url>
• make sure to deploy the custom resource definition using the command kubectl create -f deploy/crds

$ operator-sdk run local --namespace=<namespace> --operator-flags="<flags to pass>"

Grafana features not yet supported in the operator

Notifier provisioning

Grafana has provisioning support for multiple channels (notifiers) of alerts. The operator does currently not support this type of provisioning. An empty directory is mounted at the expected location to prevent a warning in the grafana log. This feature might be supported in the future.
