We're using the same exporter builder, maybe we can mutualise the code here

@Freyskeyd, thanks for reviewing this PR!

Do you mind taking over the instrumentation bit? It would be great if you pushed some changes to this branch fixing the already existing minimal setup!

I'm probably not the most appropriate person to touch the code base. I made some changes on the main.rs and Cargo.toml files, but am not entirely sure if that's the optimal solution.

We would need to keep using a cli arg or an env variable (similarly to jaeger_agent).

Most ports don't need host bindings, no? Actually this is a thought I've had for a while: With docker-compose, having links created automatically between all containers on a common network, we don't event need to specify any port (neither host nor container), no?

@sebastiendan ,

Yes you're correct. Will leave only the necessary for the PoC, thanks for spotting this!

With docker-compose, having links created automatically between all containers on a common network, we don't event need to specify any port (neither host nor container), no?

That's correct. The difference, however, is if we define the ports field but omit the ${HOST} value, docker compose will assign a random host port:

The difference, however, is if we define the ports field but omit the ${HOST} value, docker compose will assign a random host port

Yep, but what I meant is that I think we tend to use random port assignation "by default" because we think that ports should be specified. Let me describe an example:

version: '3.5'

services:
  one:
    image: ...
    ports:
      - 3000
  two:
    image: ...
    env:
      - "endpoint=http://one:3000"

Here often we would want to specify the 3000 port on one because we want two to access it, but I believe this isn't needed. (this was my comment above)
