When using 4.1.17 w/ flux I get the following error:

Helm install failed for release milvus/milvus-milvus with chart milvus@4.1.17: error while running post render on files: map[string]interface {}(nil): yaml: unmarshal errors:  
                                          line 48: mapping key "httpNumThreads" already defined at line 36

Here are the values I'm passing

Swapping pulsar for kafka fixes the problem, but that doesn't seem like a complete solution.

[haorenfsa]

looks like a bug

[haorenfsa]

em... I can't reproduce it by using helm directly. Seems to me a bug of https://fluxcd.io/

I have the same exact issue using FluxCD v2. I can follow up with more details if required. Going to attempt to use a postRenderer to resolve

After rendering the template locally, I found the offending resource: helm template miluvs zilliztech/milvus

Note: I'm not using any custom values

Output Snippet:

apiVersion: v1
kind: ConfigMap
metadata:
  name: "milvus-pulsar-proxy"
  namespace: default
  labels:
    app: pulsar
    chart: pulsar-2.7.8
    release: milvus
    heritage: Helm
    cluster: milvus-pulsar
    component: proxy
data:
  clusterName: milvus-pulsar
  httpNumThreads: "8"
  statusFilePath: "/pulsar/status"
  # prometheus needs to access /metrics endpoint
  webServicePort: "80"
  servicePort: "6650"
  brokerServiceURL: pulsar://milvus-pulsar-broker:6650
  brokerWebServiceURL: http://milvus-pulsar-broker:8080

  # Authentication Settings
  PULSAR_GC: |
    -XX:MaxDirectMemorySize=2048m
  PULSAR_MEM: |
    -Xms2048m -Xmx2048m
  httpNumThreads: "100"

This is due to a hardcoded value here: https://github.com/apache/pulsar-helm-chart/blob/pulsar-2.7.8/charts/pulsar/templates/proxy-configmap.yaml#L31C1-L31C22

Later versions of the pulsar helm chart does not include this hardcoded value.

I was unable to resolve with postrenderers, but using flat yaml via flux will probably work (if you update the rendered manifest by removing the duplicate key).
