Install

In order to evaluate the quality gates and allow self-healing in production, we have to set up monitoring to get the needed data.

Prerequisites

• Keptn project and at least one onboarded service must be available.

Setup Prometheus

After creating a project and service, you can setup Prometheus monitoring and configure scrape jobs using the Keptn CLI.

1. To install the prometheus-service, execute:

   kubectl apply -f https://raw.githubusercontent.com/keptn-contrib/prometheus-service/release-0.3.3/deploy/service.yaml
   

2. Execute the following command to set up the rules for the Prometheus Alerting Manager:

   keptn configure monitoring prometheus --project=PROJECTNAME --service=SERVICENAME
   

Verify Prometheus setup in your cluster

• To verify that the Prometheus scrape jobs are correctly set up, you can access Prometheus by enabling port-forwarding for the prometheus-service:

  kubectl port-forward svc/prometheus-service 8080 -n monitoring
  

Prometheus is then available on localhost:8080/targets where you can see the targets for the service:
