Deploying to Specific Nodes¶

You can run Robusta on specific nodes in your cluster. For example, on a hybrid Windows and Linux cluster, you'll want to ensure Robusta runs on Linux nodes.

You can configure this using either nodeSelectors or affinities.

Running Robusta on Linux Nodes¶

Add the following to your Helm values:

runner:
  nodeSelector:
    kubernetes.io/os: linux

kubewatch:
  nodeSelector:
    kubernetes.io/os: linux

Alternatively, you can configure this with nodeAffinities:

runner:
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/os
            operator: In
            values:
            - linux

kubewatch:
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/os
            operator: In
            values:
            - linux

General Tips¶

To see your node labels, run kubectl get nodes --show-labels
