Answer 1

Your yaml is not valid. Check this validator as example.

Note how on line 16 and next, uri, predicates and path are not on the same column as just before.

Valid yaml is:

server:
  port: 9190


spring:
  application:
    name: API-Gateway
  cloud:
    gateway:
      routes:
        - id: user-service
          uri: lb://DEPT-SERVICE
          predicates:
            - path=/user/**
        - id: dept-service
          uri: lb://USER-SERVICE
          predicates:
            - path=/departments/**
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka
    instance:
    preferIpAddress: true
