Eureka default zone setting is not picked up when using environment variables

springBootVersion = ‘2.0.0.M7’ springCloudVersion = ‘Finchley.M5’

docker-compose setup (stripped down):

mongo:
  ports:
      - 27017:27017
eureka:
  ports:
      - 8761:8761
test-client:
  ports:
      - 8080:8080
  environment:
      SPRING_DATA_MONGODB_HOST: "mongo"
      EUREKA_INSTANCE_PREFER_IP_ADDRESS: "true"
      EUREKA_CLIENT_SERVICEURL_DEFAULTZONE: "http://eureka:8761/eureka/"

The EUREKA_CLIENT_SERVICEURL_DEFAULTZONE environment variable is not picked up. Others, like the mongo host work ok.

Moving the setting inside the test-client application.properties works: eureka.client.service-url.defaultZone=http://eureka:8761/eureka/

I think it might be something caused by the naming of defaultZone (the service-url binds to a Map<String,String> and I don’t think the rezolver handles correctly the camelCase in defaultZone)

Probably related to https://github.com/spring-projects/spring-boot/issues/8902

Ok, guys here is the workaround for this, this is my eureka-service.properties:

management.security.enabled=false
management.info.git.mode=full

eureka.client.region=default
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true

# https://github.com/spring-cloud/spring-cloud-netflix/issues/2541
eureka.client.service-url.defaultZone=${SERVICE_URL_DEFAULT_ZONE}

And then I’m able set eureka.client.service-url.defaultZone through environment variable SERVICE_URL_DEFAULT_ZONE.

Looks creepy, but it works!

@spencergibb the proposed solution is temporary workaround, it’s not a solution for initial problem.
