performing replicas for each db, redis and worker.

[nicetry001]

all is good now deployments are working,
but i want to know how do we perform scale up
for the db, redis and workers. it seems that when i do 2 replicas for each pods it's getting confused and doesn't know where to connect itself.

Depending on the design of an application, you can't add replicas without additional considerations, which are very app-specific.

vote: can scale to many replicas
worker: can scale to many replicas
result: can't scale beyond 1 replica without LB stick sessions because it uses socket.io
db: you'd need a specific postgres replication and failover solution
redis: you'd need a specific redis replication and failover solution
