Describe the issue you're reporting

So i have a Statefulset with 2 replicas and OpenTelemetryCollector configmap

So i try to get index and logs in my opensearch use with this opentelemetry operator sidecar with 2 replicas and there are get logs from this two replicas/pods.

So the problem is there are not set Volume mount in my opentelemetry sidecar pod and i dont know how to set the volumes and volume mount path set in this below code.

This is the code :

  `        apiVersion: apps/v1
    kind: StatefulSet
    metadata:
      name: my-app
      annotations:
        sidecar.opentelemetry.io/inject: "true"
    spec:
      replicas: 2
      selector:
        matchLabels:
          app: my-app
      serviceName: "my-app"
      template:
        metadata:
          labels:
            app: my-app
          annotations:
            sidecar.opentelemetry.io/inject: "true"
            sidecar.opentelemetry.io/config: "otel-sidecar-config"
            sidecar.opentelemetry.io/volumes: '[
              {"name": "nginx-logs", "mountPath": "/var/log/nginx", "readOnly": true}
            ]'
        spec:
          nodeSelector:
            kubernetes.io/hostname: minikube
          containers:
            - name: nginx
              image: nginx:latest
              ports:
                - containerPort: 80
              volumeMounts:
                - name: nginx-logs
                  mountPath: /var/log/nginx  # ✅ Mount logs for Nginx

          volumes:
            - name: opentelemetry-config
              configMap:
                name: otel-sidecar-config

      volumeClaimTemplates:
        - metadata:
            name: nginx-logs
          spec:
            accessModes: ["ReadWriteOnce"]
            resources:
              requests:
                storage: 1Gi

             `

in this above code the set Volume try but this is not working the try is :

          sidecar.opentelemetry.io/volumes: '[
        {"name": "nginx-logs", "mountPath": "/var/log/nginx", "readOnly": true}
      ]'

@ommkwn this is an issue for the https://github.com/open-telemetry/opentelemetry-operator project. I'm going to close it here, feel free to ask on the link above (or via the CNCF Slack if that works better for you).
