# Setup grafana-operator into dedicated namespace

# 1. Create the custom resource definitions that the operator uses:
kubectl apply --namespace="${GRAFANA_NAMESPACE}" -f "${GRAFANA_OPERATOR_DIR}/deploy/crds"
# 2. Create the operator roles:
kubectl apply --namespace="${GRAFANA_NAMESPACE}" -f "${GRAFANA_OPERATOR_DIR}/deploy/roles"
# 3. If you want to scan for dashboards in other namespaces you also need the cluster roles:
kubectl apply --namespace="${GRAFANA_NAMESPACE}" -f "${GRAFANA_OPERATOR_DIR}/deploy/cluster_roles"
# 4. Deploy operator itself
kubectl apply --namespace="${GRAFANA_NAMESPACE}" -f "${GRAFANA_OPERATOR_DIR}/deploy/operator.yaml"
