[Question] How to configure emojivoto to propagate context?

[Y.Matsuda]

Hi, thanks for such a nice project!

I tried using this with emojivoto, but I'm having trouble with context propagation.
Tracing a single service works fine but the traffic across some services is traced as different trace id.

Expected Behavior

Trace ID is propagated across multiple services

Actual Behavior

A series of events across multiple services are traced as different traces

Steps to Reproduce the Problem

1. checkout https://github.com/ymtdzzz/emojivoto-opentelemetry-sample/tree/feature/ebpf
2. start k8s cluster (such as minikube)
3. deploy as described in the README
4. curl "http://your-node-ip:30084/api/list"
5. access to http://your-node-ip:30081 and check the traced data

Oh sorry, the context propagation feature hasn't been supported yet?
If that so, I'd love to wait for it to be implemented! Thank you.
