在随机端口上运行 Spring Boot 时，Eureka 无法找到端口

Question

Following are the dependencies in my local:

<dependency>
    <groupId>net.devh</groupId>
    <artifactId>grpc-server-spring-boot-starter</artifactId>
    <version>2.13.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
        

application.properties

grpc.server.port=${PORT:0}
eureka.client.serviceUrl.defaultZone=http://localhost:8791/eureka/
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}

bootstrap.properties

spring.application.name=grpc-service

Eureka server is detecting port 8080 instead of the actual port used in the Eureka client. There are similar issues reported in the past, and it was fixed as per their developers. Did I miss anything on the above mentioned config?

Update

I modified my application.properties file with the below:

grpc.server.port=${PORT:0}
server.port=${grpc.server.port}
eureka.client.serviceUrl.defaultZone=http://localhost:8791/eureka/
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}
eureka.instance.non-secure-port-enabled=true
eureka.instance.secure-port-enabled=false
eureka.instance.non-secure-port=${server.port}

But now Eureka is not detecting the service at all.

Answer 1

I was able to solve this by making the below changes:

application.xml

eureka.instance.non-secure-port-enabled=true
eureka.instance.secure-port-enabled=false
server.port=${grpc.server.port}
eureka.client.serviceUrl.defaultZone=http://localhost:8791/eureka/
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}
eureka.instance.non-secure-port=${grpc.server.port}

grpc.server.port is passed as runtime argument. After making these changes, Eureka is now detecting the exact port used in Eureka clients.
