Deploying Robusta on specific nodes

Additional configurations can be added to specify which nodes you would like for Robusta to run on by using nodeSelectors or affinity. The nodeSelector or affinity chosen should be configured for both runner and forwarder (kubewatch).

The following configuration is an example that will cause Robusta's pods to only be scheduled on nodes running linux. Our nodeSelector checks if node has a label kubernetes.io/os that has the value linux.

runner:
  nodeSelector:
    kubernetes.io/os: linux

kubewatch:
  nodeSelector:
    kubernetes.io/os: linux

Additionally we also support affinities in our pods, you can select a node in a similar way using 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

For a list of all the current labels and values you have on your nodes run kubectl get nodes --show-labels
