Problem

The current volumeMounts configuration in the Telegraf Helm chart mounts the entire ConfigMap to /etc/telegraf without using subPath:

volumeMounts:
  - name: config
    mountPath: /etc/telegraf

This approach blocks users from mounting additional configuration files (e.g., /etc/telegraf/telegraf.d/http.conf) via separate volumeMounts, because the entire /etc/telegraf directory is already occupied by the initial mount.

Proposal

To enable mounting supplemental configuration files under /etc/telegraf/telegraf.d, please consider changing the volumeMounts entry to use subPath and mount the main configuration file directly:

volumeMounts:
  - name: config
    mountPath: /etc/telegraf/telegraf.conf
    subPath: telegraf.conf
    readOnly: true

Benefit

This enables users to cleanly inject additional Telegraf input/output configurations via separate ConfigMaps or volumes, without conflicting with the main config mount.
