Deploying Phoenix with Docker: Troubleshooting Sidecar Issues

Hi Team .. I am trying to deploy the phoenix through docker and as a side car. I followed the example provided here (https://github.com/Arize-ai/openinference/tree/main/python/examples/llama-index) . I have created instrument.py and initialized it in my main API . Docker compose looks like this below image. Whenever I run the queries through streamlit, I am not seeing any trace on the phoenix server. If I run as a separate container (only phoenix) and streamlit and backend api without docker, I can see the traces and all. I am not sure, where I am doing it wrong.
