FastAPI and Uvicorn Logging

When running FastAPI app, all the logs in console are from Uvicorn and they do not have timestamp and other useful information. As Uvicorn applies python logging module, we can override Uvicorn logging formatter by applying a new logging configuration.

Meanwhile, it's able to unify the your endpoints logging with the Uvicorn logging by configuring all of them in the config file log_conf.yaml.

Before overriding:

uvicorn main:app --reload

// Sometimes, you might want to supply *some* config, but
// not necessarily *all*. Maybe your password is really

// it when your script runs.

// This interface provides a flexible approach, where
// the user is prompted for a missing key when it's
// requested - if a particular key isn't needed for a given

Start Kafka service

The following commands will start a container with Kafka and Zookeeper running on mapped ports 2181 (Zookeeper) and 9092 (Kafka).

docker pull spotify/kafka
docker run -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=kafka --env ADVERTISED_PORT=9092 --name kafka spotify/kafka

Why Spotify?

ADVERTISTED_HOST was set to kafka, which will allow other containers to be able to run Producers and Consumers.
