Testing

Running locally

To build and run this project locally, you need the following things:

• Go v1.16
• Kubectl v1.18.x
• Helm v3.5.x
• Kubernetes cluster (e.g. Docker for Desktop with Kubernetes enabled)

To deploy everything:

1. helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
2. make deploy-prometheus
3. make deploy

This will deploy httpstat-monitor and the kube-prometheus stack which includes the Prometheus Operator, Prometheus, and Grafana (as well as a few other things).

If your Kubernetes cluster is running on your local machine, run make port-forward-prometheus to have kubectl port-forward the Prometheus UI to your local machine and then navigate to http://localhost:9090/graph in your browser.

You can also do this with the Grafana UI by running make port-forward-grafana and then navigate to http://localhost:8080.

The default credentials for Grafana are:

User: admin
Password: prom-operator
