Fails with multiple nodeSelectors or tolerations:

  helm template test ./charts/pulsar \
    --set components.dekaf=true \
    --set 'dekaf.deployment.nodeSelector.disk=ssd' \
    --set 'dekaf.deployment.nodeSelector.zone=us-east-1' \
    --set 'dekaf.deployment.nodeSelector.arch=amd64' \
    --set 'dekaf.deployment.tolerations[0].key=foo' \
    --set 'dekaf.deployment.tolerations[0].operator=Equal' \
    --set 'dekaf.deployment.tolerations[0].value=bar' \
    --set 'dekaf.deployment.tolerations[0].effect=NoSchedule' \
    --set 'dekaf.deployment.tolerations[1].key=baz' \
    --set 'dekaf.deployment.tolerations[1].operator=Exists' \
    --set 'dekaf.deployment.tolerations[1].effect=NoExecute' \
    --show-only templates/dekaf-deployment.yaml \
    --debug    

Claude Code suggested either one of these fixes:

Option 1, using indent:

      nodeSelector:
{{ toYaml .Values.broker.nodeSelector | indent 8 }}
      tolerations:
{{ toYaml .Values.broker.tolerations | indent 8 }}

Option 2, using nindent:

      nodeSelector:
        {{- toYaml .Values.broker.nodeSelector | nindent 8 }}
      tolerations:
        {{- toYaml .Values.broker.tolerations | nindent 8 }}
