Simple Use-case

Start redis with docker compose

docker-compose up -d

Set a value for key test

SET testkey testvalue

Example:

docker-compose exec redis /opt/bitnami/redis/bin/redis-cli
127.0.0.1:6379> SET test testvalue
OK

Start the aiohttp application on another terminal

gunicorn app:app --worker-class aiohttp.GunicornWebWorker --workers=6 --reload

This means, the application workers subscribe to a redis channel called news.

Call the http config endpoint to see the current config values:

$> curl localhost:8000/config
{}

Go back to the redis-cli terminal and publish a update for the testkey.

127.0.0.1:6379> PUBLISH news "testkey"
(integer) 4

$> curl localhost:8000/config
{"testkey":"testvalue"}
