How worker pod knows that it needs to send the data to Redis/Postgres, generally pods get attached to service from selector,
And how voting/result app knows to send the data to redis/postgres from redis/postgres service
In the udemy, you explained that Redis/Postgres has services connecting to the apps and worker pods.
-redis service connected to voting-app and worker pod
-postgres service connected to result-app and worker pod
