Setup OpenCost in Kubernetes using Helm

#kubernetes #opencost #helm #aws

My setup is AWS and EKS.

My work based on:

Slack conversation here
Custom pricing using the OpenCost Helm Chart
Original from source

I created custom helm chart based on OpenCost helm chart(official?) here is my default values.yaml:

fullnameOverride: opencost

awsSpotDataRegion: ""
awsSpotDataBucket: ""
awsAccountId: ""

opencost:
  serviceAccount:
    create: true
    annotations:
      eks.amazonaws.com/role-arn: "xxx"
  opencost:
    exporter:
      defaultClusterId: "xxx"
      extraEnv:
        EMIT_KSM_V1_METRICS: "false"
        EMIT_KSM_V1_METRICS_ONLY: "true"
        PROM_CLUSTER_ID_LABEL: cluster
        LOG_LEVEL: info #error
      extraVolumeMounts:
        - name: opencost-conf
          mountPath: /models/aws.json
          subPath: aws.json
    prometheus:
      external:
        enabled: true
        url: "http://mimir-nginx.mimir.svc.cluster.local:80/prometheus"
      internal:
        enabled: false
    ui:
      enabled: true
  extraVolumes:
    - name: opencost-conf
      configMap:
        name: opencost-conf
        items:
          - key: "aws.json"
            path: "aws.json"

Also in my custom chart I included configmap.yaml, here is content of it:

apiVersion: v1
kind: ConfigMap
metadata:
  name: opencost-conf
data:
  aws.json: |
    {
        "provider": "custom",
        "description": "Default prices used to compute allocation between RAM and CPU. AWS pricing API data still used for total node cost.",
        "CPU": "0.031611",
        "spotCPU": "0.006655",
        "RAM": "0.004237",
        "GPU": "0.95",
        "spotRAM": "0.000892",
        "storage": "0.00005479452",
        "zoneNetworkEgress": "0.01",
        "regionNetworkEgress": "0.01",
        "internetNetworkEgress": "0.143",
        "spotLabel": "",
        "spotLabelValue": "",
        "awsServiceKeyName": "",
        "awsServiceKeySecret": "",
        "awsSpotDataRegion": "{{ .Values.awsSpotDataRegion }}",
        "awsSpotDataBucket": "{{ .Values.awsSpotDataBucket }}",
        "awsSpotDataPrefix": "",
        "athenaBucketName": "s3://x",
        "athenaRegion": "us-east-1",
        "athenaDatabase": "",
        "athenaTable": "",
        "projectID": "{{ .Values.awsAccountId }}"
    }
