Kernel 4.18+

Need access to a Kubernetes cluster.

Deploying the Kepler exporter as a daemonset to run on all nodes. The following deployment will also create a service listening on port 9102.

# build manifests file for VM+Baremetal and Baremetal only
# manifests are created in  _output/manifests/kubernetes/generated/ by default
# kubectl v1.21.0 is minimum version that support build manifest
# make build-manifest

if you are running with Baremetal only

kubectl create -f _output/manifests/kubernetes/generated/bm/deployment.yaml

if you are running with Baremetal and/or VM

kubectl create -f _output/manifests/kubernetes/generated/vm/deployment.yaml

1. Clone the kube-prometheus project to your local folder.

# git clone https://github.com/prometheus-operator/kube-prometheus

2. Deploy the whole monitoring stack using the config in the manifests directory. Create the namespace and CRDs, and then wait for them to be available before creating the remaining resources

# 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/

# cd ../kepler
# kubectl create -f manifests/kubernetes/keplerExporter-serviceMonitor.yaml

Import the pre-generated Kepler Dashboard into grafana
