Opencost Compare

This repository hosts a general set of models used to parse HTTP responses and a single test to provide a comparison between two versions of opencost.

Requirements

• The version of opencost that you wish to compare should exist in the ../opencost directory relative to this repository.
• A "target" opencost version running in Kubernetes (and accessible Service) that can be used to compare against the local version.
• A Prometheus server that is being used by the target (and accessible Service).

Usage

• port-forward the remote [shared] Prometheus Service to your local machine on port 9011

kubectl port-forward -n <namespace> svc/<prometheus-server> 9011:80

• port-forward the remote [shared] opencost Service to your local machine on port 9007

kubectl port-forward -n <namespace> svc/<opencost-service> 9007:9003

• Run the test with KUBECOST_NAMESPACE=<namespace> and turn off timeout:

KUBECOST_NAMESPACE=kubecost go test ./... -v -timeout=0
