(obsolete) OptScale Kubernetes Cost Metrics Collector

This approach of k8s cost metrict collection for OptScale is obsolete due to multiple architectural flaws. Reworked implementation can be found here - https://github.com/hystax/helm-charts/tree/main/charts/kube-cost-metrics-collector

Ready-to-deploy setup of components necessary for kubernetes cost management and FinOps in Hystax OptScale.

Components

• Prometheus
• Prometheus node-exporter module
• kube-state-metrics
• nginx (optional, for setting up authentication)

Prerequisites

• Kubernetes 1.16+

Description

Helm chart for the OptScale Kubernetes Collector project, which is created to collect Kubernetes resources information and share it with OptScale FinOps project - https://hystax.com/optscale/.

Kubernetes YAML (LoadBalancer based configuration)

These resources can be deployed with the following single command:

kubectl apply -f https://raw.githubusercontent.com/hystax/optscale-k8s-collector-helm-chart/master/optscale-agent.yaml

Helm install configurations

Helm Prerequisites

• Helm 3+

NodePort example (recommended for virtual machines based clusters):

helm install --namespace optscale --create-namespace --set nginx.service.type=NodePort --set nginx.service.enabledExternalPort=true --set nginx.service.externalPort=31222 --set nginx.passwd=$(htpasswd -nbm "optscale" "<SOME_PASSWORD>") monitoring .

LoadBalancer example (recommended for cloud based clusters):

helm install --namespace optscale --create-namespace --set nginx.service.internalPort=4433 --set nginx.passwd=$(htpasswd -nbm "optscale" "<SOME_PASSWORD>") monitoring .

Helm chart parameters

The following table lists the commonly used configurable parameters of the Helm chart and their default values.

Parameter	Description	Default
nginx.enabled	if false, use another way to expose the Prometheus port	true
nginx.service.type	NodePort or LoadBalancer	LoadBalancer
nginx.service.internalPort	Internal NGINX Server Port Number	4433
nginx.passwd	MD5 hash of the username and password to login to the Agent metrics	optscale:<SOME_MD5_PASSWORD>
nginx.service.enabledExternalPort	use true for NodePort and false - LoadBalancer	false
nginx.service.externalPort	Agent external Node port number	31222
