Spring boot Netflix Eureka:无法将环境变量用作实例主机名,spring-boot,docker-compose,microservices,netflix-eureka,Spring Boot,Docker Compose,Microservices,Netflix Eureka,我想使用docker compose中的环境变量作为实例主机名。由于某些原因，我无法构建项目，因为它总是给出错误，但如果我将实例主机名更改为localhost，它就可以正常工作。我尝试设置eureka.instance.preferIpAddress=true，但仍然出现错误 server.port=9001 eureka.instance.preferIpAddress=true # <------ I tried adding this line, but still not work

我想使用docker compose中的环境变量作为实例主机名。由于某些原因，我无法构建项目，因为它总是给出错误，但如果我将实例主机名更改为localhost，它就可以正常工作。我尝试设置eureka.instance.preferIpAddress=true，但仍然出现错误

server.port=9001
eureka.instance.preferIpAddress=true # <------ I tried adding this line, but still not working
eureka.instance.hostname=localhost # <------ this one work just fine
eureka.instance.hostname=${HOSTNAME} # <------ this one always gives error
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka

这就是我试图构建eureka项目时的错误
