Prombench in KIND

Run prombench tests in Kubernetes In Docker.

Setup prombench

  1. Install KIND
  2. Create the KIND cluster
  3. Deploy monitoring components

Create the Cluster Cluster

  • Create multi node KIND cluster
  • Set the following environment variables and deploy the cluster.
export CLUSTER_NAME=prombench
export PR_NUMBER=<PR to benchmark against the selected $RELEASE>

../infra/infra kind cluster create -v PR_NUMBER:$PR_NUMBER -v CLUSTER_NAME:$CLUSTER_NAME \
    -f manifests/cluster_kind.yaml
  • Remove taint(node-role.kubernetes.io/master) from prombench-control-plane node for deploying nginx-ingress-controller
kubectl taint nodes $CLUSTER_NAME-control-plane node-role.kubernetes.io/master-

Deploy monitoring components

Collecting, monitoring and displaying the test results and logs

  • [Optional] If used with the Github integration generate a GitHub auth token. 
export GRAFANA_ADMIN_PASSWORD=password
export DOMAIN_NAME=prombench.prometheus.io # Can be set to any other custom domain or an empty string when not used with the Github integration.
export OAUTH_TOKEN=<generated token from github or set to an empty string " ">
export WH_SECRET=<github webhook secret>
export GITHUB_ORG=prometheus
export GITHUB_REPO=prometheus
export SERVICEACCOUNT_CLIENT_EMAIL=<Your Email address>

../infra/infra kind resource apply -v CLUSTER_NAME:$CLUSTER_NAME -v DOMAIN_NAME:$DOMAIN_NAME \
    -v GRAFANA_ADMIN_PASSWORD:$GRAFANA_ADMIN_PASSWORD \
    -v OAUTH_TOKEN="$(printf $OAUTH_TOKEN | base64 -w 0)" \
    -v WH_SECRET="$(printf $WH_SECRET | base64 -w 0)" \
    -v GITHUB_ORG:$GITHUB_ORG -v GITHUB_REPO:$GITHUB_REPO \
    -v SERVICEACCOUNT_CLIENT_EMAIL:$SERVICEACCOUNT_CLIENT_EMAIL \
    -f manifests/cluster-infra
  • Set NODE_NAME, INTERNAL_IP and NODE_PORT environment variable
export NODE_NAME=$(kubectl get pod -l "app=grafana" -o=jsonpath='{.items[*].spec.nodeName}')
export INTERNAL_IP=$(kubectl get nodes $NODE_NAME -o jsonpath='{.status.addresses[?(@.type=="InternalIP")].address}')
export NODE_PORT=$(kubectl get -o jsonpath="{.spec.ports[0].nodePort}" services grafana)
  • The services will be accessible at:
echo "Grafana: http://$INTERNAL_IP:$NODE_PORT/grafana"
echo "Prometheus: http://$INTERNAL_IP:$NODE_PORT/prometheus-meta"
echo "Logs: http://$INTERNAL_IP:$NODE_PORT/grafana/explore"

Usage

Start a benchmarking test manually

  • Set the following environment variables.
export RELEASE=<master/main or any prometheus release(ex: v2.3.0) >
export PR_NUMBER=<PR to benchmark against the selected $RELEASE>
  • Deploy the k8s objects
../infra/infra kind resource apply -v CLUSTER_NAME:$CLUSTER_NAME \
    -v PR_NUMBER:$PR_NUMBER -v RELEASE:$RELEASE -v DOMAIN_NAME:$DOMAIN_NAME \
    -v GITHUB_ORG:${GITHUB_ORG} -v GITHUB_REPO:${GITHUB_REPO} \
    -f manifests/prombench/benchmark

Deleting benchmark infra

../infra/infra kind cluster delete -v PR_NUMBER:$PR_NUMBER -v CLUSTER_NAME:$CLUSTER_NAME \    
    -f manifests/cluster_kind.yaml
