Install Kubecost on Redhat OpenShift
Currently, there are two main options to deploy Kubecost on Red Hat OpenShift Cluster (OCP).
Kubecost is installed with Cost Analyzer and Prometheus as a time-series database. Data is gathered by the Prometheus installed with Kubecost (bundled Prometheus). Other metrics are scraped by bundled Prometheus from OCP monitoring stack managed components like Kube State Metrics (KSM), Openshift Service Mesh (OSM), CAdvisor, etc .... Kubecost then pushes and queries metrics to/from bundled Prometheus. Enterprise setup could also work with Thanos as an additional component.
The standard deployment is illustrated in the following diagram:
Standard deployment
Kubecost is installed with the core components only (cost model, frontend) without bundled Prometheus and other components. Grafana agent is installed as part of the solution to scrape the metrics from OCP monitoring stack managed components and Kubecost
/metrics endpoint to write the data back to the Grafana Cloud managed Prometheus (Grafana Prometheus) instance. Kubecost reads the metrics directly from Grafana managed Prometheus.The Grafana managed Prometheus deployment is illustrated in the following diagram:
Grafana managed Prometheus deployment
- You have an existing OpenShift cluster.
- You have appropriate access to that OpenShift cluster to create a new project and deploy new workloads.
Run the following Helm install command to install Kubecost:
helm upgrade --install kubecost \
--repo https://raw.githubusercontent.com/kubecost/openshift-helm-chart/main cost-analyzer \
--namespace kubecost --create-namespace \
-f https://raw.githubusercontent.com/kubecost/openshift-helm-chart/main/values-openshift.yaml
If you want to install Kubecost with your desired cluster name, you can use the following commands:
Note: Remember to replace CLUSTER_ID's value by your desired value
export CLUSTER_ID="CLUSTER_OCP"
helm upgrade --install kubecost \
--repo https://raw.githubusercontent.com/kubecost/openshift-helm-chart/main cost-analyzer \
--namespace kubecost --create-namespace \
-f https://raw.githubusercontent.com/kubecost/openshift-helm-chart/main/values-openshift.yaml \
--set kubecostProductConfigs.clusterName=${CLUSTER_ID} \
--set prometheus.server.global.external_labels.cluster_id=${CLUSTER_ID}
Wait for all pods to be ready.
Create a route to the service
kubecost-cost-analyzer on port 9090 of the kubecost project. You can learn more about how to do it on your OpenShift portal in this LINKKubecost will be collecting data, please wait 5-15 minutes for the UI to reflect the resources in the local cluster.
- You have created a Grafana Cloud account and you have permissions to create Grafana Cloud API keys
- Add required service account for grafana-agent to
hostmount-anyuidSCC:
oc adm policy add-scc-to-user hostmount-anyuid system:serviceaccount:kubecost:grafana-agent
On the existing K8s cluster that you intend to install Kubecost, run the following commands to install Grafana agent to scrape the metrics from Kubecost /metrics endpoint. The script below installs Grafana agent with the necessary scraping configuration for Kubecost, you may want to add an additional scrape configuration for your setup. Please remember to replace the following values with your actual Grafana cloud's values:
- REPLACE-WITH-GRAFANA-PROM-REMOTE-WRITE-ENDPOINT
- REPLACE-WITH-GRAFANA-PROM-REMOTE-WRITE-USERNAME
- REPLACE-WITH-GRAFANA-PROM-REMOTE-WRITE-API-KEY
- REPLACE-WITH-YOUR-CLUSTER-NAME

cred="$( echo $NAME:$PASSWORD | base64 )"; curl -H "Authorization: Basic $cred" https://<REPLACE-WITH-GRAFANA-PROM-QUERY-ENDPOINT>/api/v1/query?query=up
- Create K8s secret name dbsecret:
kubectl create secret generic dbsecret \

- Verify if the credentials appears correctly - Optional (Any trailing space or new line etc ...)
kubectl -n kubecost get secret dbsecret -o json | jq '.data | map_values(@base64d)'
To set up recording rules in Grafana Cloud, download the cortextool CLI utility. While they are optional, they offer improved performance.

Optionally, you can also add our Kubecost Dashboard for Grafana Cloud to your organization to visualize your cloud costs in Grafana.
You can uninstall Kubecost from your cluster with the following command.
helm uninstall kubecost --namespace kubecost
