Docker compose com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

Question

I tried to implement an example of Spring Boot Microservice examples. I have a problem in docker-compose file.

Eureka server and api gateways throws an issue defined below while there is no issue in config server.

Here is the issue : com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

Here is the code snippets for config server.

configserver:
    image: configserver
    container_name: configServer
    build:
      context: ./configserver
      dockerfile: Dockerfile
    environment:
      CONFIGSERVER_URI: "http://localhost:9191"
      CONFIGSERVER_PORT: "9191"
    ports:
      - "9191:9191"
    networks:
      backend:
        aliases:
          - "configserver"

Here is the code snippets for eureka server

eurekaserver:
    image: eurekaserver
    ports:
      - "8761:8761"
    build:
      context: ./discoveryserver
      dockerfile: Dockerfile
    environment:
      CONFIGSERVER_URI: "http://localhost:9191"
      CONFIGSERVER_PORT: "9191"
      EUREKASERVER_URI: "http://localhost:8761/eureka/"
      EUREKASERVER_PORT: "8761"
    depends_on:
      configserver:
        condition: service_started
    networks:
      backend:
        aliases:
          - "eurekaserver"

Here is the code snippets for api gateway server.

gatewayserver:
    image: gatewayserver
    ports:
      - "8600:8600"
    build:
      context: ./api-gateway
      dockerfile: Dockerfile
    environment:
      PROFILE: "default"
      SERVER_PORT: "8600"
      CONFIGSERVER_URI: "http://localhost:9191"
      EUREKASERVER_URI: "http://localhost:8761/eureka/"
      EUREKASERVER_PORT: "8761"
      CONFIGSERVER_PORT: "9191"
    depends_on:
      configserver:
        condition: service_started
      eurekaserver:
        condition: service_started
    networks:
      backend:
        aliases:
          - "gateway"

Here is all docker-compose.yml : Link

Answer 1

Services are no longer running on localhost.

So change:

EUREKASERVER_URI: "http://localhost:8761/eureka/"

To corresponding service container name, take Eureka server for instance:

EUREKASERVER_URI: "http://eurekaserver:8761/eureka/"

See Github issue.
