Set up Kepler on kind

git clone https://github.com/sustainable-computing-io/kepler.git

export CLUSTER_PROVIDER='kind'
export PROMETHEUS_ENABLE="true"
export GRAFANA_ENABLE="true"
make cluster-up

git clone --depth 1 https://github.com/prometheus-operator/kube-prometheus
cd kube-prometheus

kubectl apply --server-side -f manifests/setup
until kubectl get servicemonitors --all-namespaces ; do date; sleep 1; echo ""; done
kubectl apply -f manifests/

This will create the monitoring namespace and CRDs, and then wait for them to be available before creating the remaining resources. During the until loop, a response of No resources found is to be expected. This statement checks whether the resource API is created but doesn't expect the resources to be there.

Create Kepler manifests

make build-manifest OPTS="CI_DEPLOY PROMETHEUS_DEPLOY DEBUG_DEPLOY"

kubectl apply -f _output/generated-manifest/deployment.yaml

Deploy Otel Collector

kubectl apply -f https://raw.githubusercontent.com/husky-parul/otel-observability/main/otel/otel-collector.yaml

Get Kepler Prom metrics into otel collector via logging


kubectl get pods
