Port mapping using gateway and microservices in springboot - spring

Question

Maybe I do not understand well the mapping of the port using docker-compose and a very simple gateway. All the project is working fine except for the gateway.
My application.yml is the following:
spring:
application:
name: api-gateway
cloud:
gateway:
routes:
- id: usermanager
uri: http://usermanager:1111
predicates:
- Path=/user/
- id: catalogmanager
uri: http://catalogmanager:2222
predicates:
- Path=/catalog/
- id: paymanager
uri: http://paymanager:3333
predicates:
- Path=/payment/**
While the docker-compose is:
version: '3.4'
x-common-variables: &common-variables
DATASOURCE_USER: ${DB_USER}
DATASOURCE_PASSWORD: ${DB_PASSWORD}
DATASOURCE_PORT: ${DB_PORT}

I'm trying to create a simple gateway that the request made on localhost/8080 route through the different microservices. Can someone explain me if something is wrong configured?
