How to add request-id/trace-id to http request header?

Hi @yfractal
You are right, appending to map is more complex than appending to slice and is not a logic we implemented yet.
Until we implement the map operations the way we do it today is by appending to the slice created in the function that iterates over the map. In an HTTP client example a good candidate would be: https://cs.opensource.google/go/go/+/master:src/net/http/header.go;l=173

Both of these tasks (HTTP client support + appending to maps) are on our roadmap and will be implemented in future versions. If you would like to help, we will be happy to accept a PR 😄

Thanks edeNFed, I will try to figure how to do this, but I'm not sure when I can achieve this, I'm short of knowledge both C, eBPF and golang 😂

No worries, this will be added very soon
