How to run the simulator

Initialize postgres database

docker run --name my-postgres -e POSTGRES_PASSWORD=secret -p 5432:5432 -d postgres:17-alpine

You can connect to database with password "secret"

psql -h localhost -p 5432 -U postgres -d postgres

Now run delivery service simulator

go run ./cmd/delivery/main.go

delivery service should be run in mulitple instances by putting delivery services behind a nginx proxy you can distribute worker processes over multiple instances

Also run 3pl dumb service too

go run ./cmd/3pl/main.go

At the end generate simulated shipment requests via seeder script

go run ./cmd/seeder/main.go
