Kubecost helm chart

Helm chart for the Kubecost project, which is created to monitor and manage Kubernetes spend. Please contact team@kubecost.com or visit kubecost.com for more info.

To install via helm 3, run the following commands:

helm upgrade --install kubecost --namespace kubecost --create-namespace \
  --repo https://kubecost.github.io/cost-analyzer/ cost-analyzer \
  --set kubecostToken="aGVsbUBrdWJlY29zdC5jb20=xm343yadf98"

While Helm is the recommended install path for Kubecost, these resources can alternatively be deployed with a single-file manifest using the following command:

kubectl apply -f https://raw.githubusercontent.com/kubecost/cost-analyzer-helm-chart/develop/kubecost.yaml --namespace kubecost

The following table lists commonly used configuration parameters for the Kubecost Helm chart and their default values.

Adjusting Log Output

The log output can be adjusted while deploying through Helm by using the LOG_LEVEL and/or LOG_FORMAT environment variables.

For example, to set the log level to trace the following flag can be added to the helm command:

    --set 'kubecostModel.extraEnv[0].name=LOG_LEVEL,kubecostModel.extraEnv[0].value=trace'

LOG_FORMAT options:

JSON - A structured logging output: {"level":"info","time":"2006-01-02T15:04:05.999999999Z07:00","message":"Starting cost-model (git commit \"1.91.0-rc.0\")"}

pretty - A nice human readable output: 2006-01-02T15:04:05.999999999Z07:00 INF Starting cost-model (git commit "1.91.0-rc.0")
