VictoriaMetrics supports Prometheus-compatible relabeling for all the ingested metrics if `-relabelConfig` command-line flag points
to a file containing a list of [relabel_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config) entries.
See [this article with relabeling tips and tricks](https://valyala.medium.com/how-to-use-relabeling-in-prometheus-and-victoriametrics-8b90fc22c4b2).
Example contents for `-relabelConfig` file:
```yml
# relabel_config.yml
# Add {cluster="dev"} label.
- target_label: cluster
replacement: dev
# Drop the metric (or scrape target) with `{__meta_kubernetes_pod_container_init="true"}` label.
- action: drop
source_labels: [__meta_kubernetes_pod_container_init]
regex: true
