#### resourceAttributes
The `resourceAttributes` option allows setting the resource attributes sent along the traces.
Traefik also supports the `OTEL_RESOURCE_ATTRIBUTES` env variable to set up the resource attributes.
!!! info "Kubernetes Resource Attributes Detection"
Additionally, Traefik automatically discovers the following [Kubernetes resource attributes](https://opentelemetry.io/docs/specs/semconv/non-normative/k8s-attributes/) when running in a Kubernetes cluster:
- `k8s.namespace.name`
- `k8s.pod.uid`
- `k8s.pod.name`
Note that this automatic detection can fail, like if the Traefik pod is running in host network mode.
In this case, you should provide the attributes with the option or the env variable.

## resourceAttributes
The `resourceAttributes` option allows setting the resource attributes sent along the traces.
Traefik also supports the `OTEL_RESOURCE_ATTRIBUTES` env variable to set up the resource attributes.
!!! info "Kubernetes Resource Attributes Detection"
Additionally, Traefik automatically discovers the following [Kubernetes resource attributes](https://opentelemetry.io/docs/specs/semconv/non-normative/k8s-attributes/) when running in a Kubernetes cluster:
- `k8s.namespace.name`
- `k8s.pod.uid`
- `k8s.pod.name`
Note that this automatic detection can fail, like if the Traefik pod is running in host network mode.
In this case, you should provide the attributes with the option or the env variable.
