High Availability Mode

High availability (HA) mode is only officially supported on Kubecost Enterprise plans.

Kubecost v2.2 introduces a new flag haMode for the frontend service. This flag changes the service name that the ingress needs to target.

This is the first step in enabling high availability for Kubecost. Future versions will expand the HA configuration to include backend services.

With frontend HA, the frontend will now be a dedicated deployment with two replicas. This allows for the ability to do rolling upgrades of the frontend pods during upgrades and configuration changes.

The primary benefit to this mode is that the Kubecost UI, including diagnostics, is available even if the backend services are not healthy.


Update your values.yaml file with the following minimum configuration:

  deployMethod: haMode
  federatedStorageConfigSecret: federated-store
  clusterName: [CLUSTER_ID]
        cluster_id: [CLUSTER_ID]

Confirm HA mode is enabled

You can check the status of HA mode in the Kubecost UI by selecting Settings from the left navigation, then under 'Never lose your cost visibility', ensure 'High availability mode' is enabled.
