I installed Tempo (microservices mode) in a Kubernetes cluster via Helm Chart.

I want to deploy all Tempo pods on the EKS node group that I have exclusively for monitoring purposes. I added the following configuration on the rest of the components (distributor, ingester, etc), but only on the memcached tool there is not tolerations settings on the helm chart values file.

Configuration:

    affinity: |
      nodeAffinity:
        requiredDuringSchedulingIgnoredDuringExecution:
          nodeSelectorTerms:
            - matchExpressions:
                - key: node-type
                  operator: In
                  values:
                    - monitoring
    tolerations:
      - key: monitoring
        value: dedicated
        operator: Equal
        effect: NoSchedule

Desired solution

Have the possibility to configure tolerations in the memcached service using Helm Chart values.
