Jaeger does not show any traces

[webmstk]

Is it possible to add some example how to use it with jaeger?

I have the following code:

Cargo.toml

[dependencies]
opentelemetry = "0.31.0"
opentelemetry-stdout = "0.31.0"
opentelemetry-otlp = { version = "0.31.0", features = ["grpc-tonic"] }
opentelemetry_sdk = "0.31.0"

tracing = "0.1.44"
tracing-opentelemetry = "0.32.0"
tracing-subscriber = "0.3.22"

tokio = { version = "1", features = ["full"] }

main.rs

use tracing_subscriber::layer::SubscriberExt;
use tracing_subscriber::util::SubscriberInitExt;

use opentelemetry::trace::TracerProvider;
use opentelemetry_sdk::trace::SdkTracerProvider;

#[tokio::main]
async fn main() {
    let stdout_log_layer = tracing_subscriber::fmt::Layer::default()
        .with_target(false)
        .with_ansi(true);

    let tracer = tracer_provider().tracer("example_tracer");
    let otel_trace_layer = tracing_opentelemetry::layer().with_tracer(tracer);

    let _ = tracing_subscriber::registry()
        .with(stdout_log_layer)
        .with(otel_trace_layer)
        .init();

    {
        let root = tracing::span!(tracing::Level::ERROR, "app_start", work_units = 2);
        let _enter = root.enter();

        tracing::error!("This event will be logged in the root span.");
    }
}

fn tracer_provider() -> SdkTracerProvider {
    let exporter = opentelemetry_otlp::SpanExporter::builder()
        .with_tonic()
        .build()
        .expect("Failed to create span exporter");

    SdkTracerProvider::builder()
        .with_batch_exporter(exporter)
        .with_simple_exporter(opentelemetry_stdout::SpanExporter::default())
        .build()
}

Jaeger:

docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 4317:4317 \
  -p 4318:4318 \
  -p 14250:14250 \
  -p 14268:14268 \
  -p 14269:14269 \
  -p 9411:9411 \
  jaegertracing/all-in-one:latest

Run:

cargo run

I can see output in stdout, but there is no information in Jaeger. I have no idea how to debug this :(

There's an example in README.md, did that not work for you?
