LGTM, why change the recommendationservice's container_name though? The main reason why these were added was just for readability of the console logs. Trying to keep consistent hyphenated service name for them

[dineshg13]

Because of hyphen in container name, the address of container would change . It needs to be consist with ones defined in .env file .

opentelemetry-demo/.env

Line 44 in 860a35d

RECOMMENDATION_SERVICE_ADDR=recommendationservice:${RECOMMENDATION_SERVICE_PORT}

Were you seeing an error? All the other services addresses work and they use the unhyphenated version, which is the actual root name of the service, not the container name. I believe we want to use the service name here, if we scale up to multiple recommendation service containers running at the same time, I think this would only provide traffic to one or completely break if docker compose decides to name them recommendationservice-1 and recommendationservice-2

@mic-max Thanks for catching this. I have revert the container name. Initially i was seeing errors during startup of frontend, but looks like they are just transient ones, and few minutes it seems to be working as expected.

This PR broke the load generator, primarily through removing locust from requirements.txt.

Reverting PR.
