chatqna-xeon-backend-server crashes due to ports not defined

[liuyingshanx]

What I did:
I followed https://github.com/opea-project/GenAIExamples/blob/main/ChatQnA/docker/xeon/README_qdrant.md and did all steps to set up chatQnA via docker compose using qdrant as vector db. I Rebuild all images in the latest main branch(Aug. 22, ac324a9 is the latest commit id) including opea/chatqna:latest, and apply docker compose yaml file.

What happens
Mega container chatqna-xeon-backend-server crashes, the error was:

How I workaround
Before applying docker compose yaml file, set those envs:

export EMBEDDING_SERVICE_PORT=6044
export RETRIEVER_SERVICE_PORT=6045
export RERANK_SERVICE_PORT=6046
export LLM_SERVICE_PORT=6047

@liuyingshanx
There is a fix for exporting the ports into docker instance in below PR
#569

Could you try again with the latest codes?

thanks
