Hi @kilbac ,
I shot your question to one of the devs internally and this was the guidance they provided. I read through it and agree that I think it will:
The OpenTelemetry collector when following the demo runs within a docker container. Localhost points, in this case, to the localhost of the docker container, NOT to the broker container (assuming its running on the same machine). Theres a couple ways to fix this. One is to add --network=host to the OpenTelemetry container, since localhost will now point to the localhost of the machine rather than the docker container. Another is to add both the OpenTelemetry container and the broker to the same network, and then point to the broker container’s hostname (if in docker compose it might be something like solbroker ). Lastly, a “depends on” can be added if the broker is in the same docker compose. The same thing can happen when sending from the collector to jaeger. They also need to be on the same network or depends on or host networked. Essentially they must be able to communicate with eachother. Easiest in my opinion for PoC is to put them all in the same docker-compose.yml and add them all to the same network, then refer to the other containers based on their names, e.g. jaeger:14250 or solbroker:5672 Hope that helps!
