(Update docs?) Health check failing due to unset BASE_URL

[cyhyraethz]

The docs use the API_URL environment variable in the docker compose file, but the health check uses BASE_URL which is not set anywhere. When I renamed API_URL to BASE_URL the health check started passing and the container shows healthy status.

Is it possible there was a change at some point to the name of the environment variable being used and the docs were updated in one place but not the other, causing the health check to reference an unset environment variable?
