Holmes-Only Install (Without the Runner)¶

The robusta chart can install HolmesGPT alone, without the Robusta runner or kubewatch. Holmes connects to the Robusta platform directly, so Ask Holmes, Triggered Workflows, alert triage and scheduled prompts work for the cluster.

Setting runner.enabled: false turns this on. The default is true, so existing installs are unchanged.

Values¶

Start from your generated_values.yaml and add:

runner:
  enabled: false
kubewatch:
  enabled: false
enableHolmesGPT: true

clusterName: my-cluster
globalConfig:
  account_id: <ACCOUNT_ID>
  signing_key: <SIGNING_KEY>
sinksConfig:
  - robusta_sink:
      name: robusta_ui_sink
      token: <ROBUSTA_UI_TOKEN>

holmes:
  additionalEnvVars:
    - name: ROBUSTA_AI
      value: "true"

The chart still renders robusta-playbooks-config-secret, with only the cluster name, account id, signing key and robusta sink. Holmes reads its platform credentials from it. Rendering fails if enableHolmesGPT is false or if there is no robusta_sink. Other sinks are ignored, because only the runner uses them.

If the sink token is a reference such as {{ env.UI_SINK_TOKEN }}, the variable must be set on Holmes, not on the runner. Add it under holmes.additionalEnvVars:

holmes:
  additionalEnvVars:
    - name: UI_SINK_TOKEN
      valueFrom:
        secretKeyRef:
          name: <SECRET_NAME>
          key: <SECRET_KEY>

Sending alerts¶

With no runner, there is no in-cluster <release>-runner endpoint for Alertmanager. Send alerts to the Robusta platform directly instead. See Send alerts from AlertManager.

If you use the bundled Prometheus stack (enablePrometheusStack: true), its default robusta receiver points at the runner, and rendering fails until you replace it:

kube-prometheus-stack:
  alertmanager:
    config:
      receivers:
        - name: 'null'
        - name: robusta
          webhook_configs:
            - url: 'https://api.robusta.dev/webhooks?type=alert&origin=alertmanager&account_id=<ACCOUNT_ID>&cluster=<CLUSTER_NAME>'
              send_resolved: true
              http_config:
                authorization:
                  type: Bearer
                  credentials: <ROBUSTA_API_KEY>
