</CodeBlockConfig>

This Docker Compose configuration sets up Tempo to collect traces from the Docker environment. The traces are sent to Tempo using the Loki logging driver, which allows for seamless integration with Grafana. This Docker Compose configuration also refers to a `tempo/tempo.yaml` file that contains the Tempo configuration.
