IndicatorDocument is a resource that allow for indicators, thresholds, and layouts to be configured for a given product.

Controllers

Grafana

The grafana-indicator-controller configures dashboards for grafana based on IndicatorDocuments.

Prometheus

The prometheus-indicator-controller configures alerting rules for prometheus based on IndicatorDocuments.

Deployment

You can deploy the SRE resources by:

kubectl apply -Rf config

Cluster setup

# Create new cluster
gcloud container clusters create $NAME --zone us-central1-a

# Provide admin privileges to self
kubectl create clusterrolebinding cluster-admin-binding --clusterrole cluster-admin --user $(gcloud config get-value account)

# Ensure kubeconfig is pointing at the right cluster
kubectl config get-contexts

# [Optional] Point at the right cluster
gcloud container clusters get-credentials $NAME -z us-central1-a

# Initialize Helm
helm init
helm repo update
kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
helm init --service-account tiller --upgrade

# Create Grafana namespace
kubectl create ns grafana

# Install Grafana helmchart
helm install stable/grafana --values helm_config/grafana_values.yml --name grafana --namespace grafana

# Create Prometheus namespace
kubectl create ns prometheus

# Install Prometheus helmchart
helm install stable/prometheus --name prometheus --namespace prometheus

# MIP components
kubectl apply -f config

# Apply a simple indicatordocument
kubectl apply -f test/valid/simple.yml
