How does Milvus install by Helm can support dynamic configuration changes when I changed config user.yaml in config map?

I see document in K8s
A container using a ConfigMap as a subPath volume mount will not receive ConfigMap updates.
And helm use subPath:

- name: milvus-config
  mountPath: /milvus/configs/user.yaml
  subPath: user.yaml
  readOnly: true

@anhnch30820 For now it's supported in milvus-operator , we'll migrate it to helm soon.

Hi @haorenfsa, Does helm support dynamic for now?

@anhnch30820 No, I haven't got time to manage that. l list the changes needed below., so that you may change your deployment for dynamic config. Or if you're interested, you could also make a patch for our chart.

Each deploy should be added with:

• an starting script /milvus/tools/run.sh and related volumeMounts.
• an initContainer to copy binaries needed for run.sh
• change the volumeMount's path, and remove subpath field.
