+2. Before applying benchmarking objects , You have two choices to make:  
+- **Option 1: Download data from object storage**
+
+   To download data from object storage, create a Kubernetes secret with exact named `bucket-config` and file name ```object-config.yml```  with the necessary credentials as per your object storage. This secret enables access to the stored data.
+> Note: Make sure this secret applied before ```3b_prometheus-test_deployment.yaml```
+- **Option 2: Skip downloading data**
+
+   If you don’t need to download data, edit the `3b_prometheus-test_deployment.yaml` file:
+
+   - Remove the `bucket-config` volume section from.
+   - Remove the `volumeMount` section name `bucket-config` from `data-downloader`.
+> Note: You have to remove these two sections from both prometheus-test-pr-{{ .PR_NUMBER }} and prometheus-test-{{ normalise .RELEASE }} deployments.

+3. Deploy the Kubernetes objects:
    > **_Note:_** If you encounter a `too many files open` error caused by promtail, increase the default value of `/proc/sys/fs/inotify/max_user_instances` from 128 to 512:

    > sudo sysctl fs.inotify.max_user_instances=512
