spring boot application properties not read correctly – Docker

For some reason it does not seem like application.yml is correctly read in my spring boot application. No matter what I try with the application tries to connect to eureka on local host.

spring:
  application:
    name: oneminute-dashboard
  server:
    port: 5001
  eureka:
    client:
      service-url:
        defaultZone: http://eureka-server:8761/eureka
  sql:
    init:
      platform: postgres
  datasource:
    url: jdbc:postgresql://db:5432/dev_onemin_percent
    username: xxxx
    password: xxxx
  jpa:
    hibernate:
      ddl-auto: update
    database-platform: org.hibernate.dialect.PostgreSQLDialect

Looking at the log I see that it tries to connect to localhost. I have the same problem with postgres but there the datasource can be overridden from the docker-compose file.

    This documentation uses serviceUrl instead of service-url
    https://cloud.spring.io/spring-cloud-static/Edgware.SR6/multi/multi__service_discovery_eureka_clients.html

    eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

    It will be

    default-zone: http://eureka-server:8761/eureka

    and not

    defaultZone: http://eureka-server:8761/eureka
