We should also add env vars to the host and pr-tests docker-compose files.

Otherwise LGTM

Nice to see more OpenTelemetry everywhere.

You might also want to configure axum so it catches the trace ID in incoming requests. See here. You may also add TraceLayer to automatically create spans on all incoming requests (see

osrd/editoast/src/main.rs

Line 392 in 5977531

.layer(TraceLayer::new_for_http())

)).

Thanks for the improvements.

Not working in local. Osrdyne logs:

Error: missing field `service_name` for key "OPENTELEMETRY" in `OSRDYNE__` environment variable(s)

Not tested but looks ok :)
