Spring Cloud Configユーレカの最初のアプローチが機能しない

Question

私はSpring Cloud Eurekaマイクロサービスアプリケーションを開発しています。私は自分のサービスをEurekaの最初の方法で設定サービスに接続したいと思っています。マイクロサービスは、ドッキング用のコンテナとしてパッケージ化され、ドッキング用の構成で展開されます。アプリケーションは、によって構成されています

1. myapp-service-registry：春クラウド構成サービスサーバ
2. myapp-service-test：その設定データを取るようにしてください例microservice春クラウドユーレカ
3. myapp-config-serviceで実装サービスレジストリサービスユーレカファーストのアプローチでこれに接続することで、設定サービスから。

設定サービスへの接続が以下のように失敗します。まず、いくつかのコンフィギュレーションデータの：ここで

はmyapp-service-registryあるのapplication.yml：ここ

server: 
    port: ${PORT:8761} 

eureka: 
    client: 
    registerWithEureka: false 
    fetchRegistry: false 
    server: 
    waitTimeInMsWhenSyncEmpty: 0 

myapp-config-serviceさんapplication.yml：

server: 
    port: ${MYAPP_CONFIG_SERVICE_PORT:8888} 

spring: 
    cloud: 
    config: 
     server: 
     git: 
      uri: ${MYAPP_CONFIG_SERVICE_GIT_URI} 
    config: 
    name: myapp-config-service 

# eureka service registry client 

eureka: 
    client: 
     serviceUrl: 
      defaultZone: http://${SERVICE_REGISTRY_HOST}:${SERVICE_REGISTRY_PORT}/eureka/ 
    instance: 
     preferIpAddress: true 

コンフィグサーバとクライアントが configserver-eurekaと eureka-firstのように初期化されている

サンプルはhttps://github.com/spring-cloud-samples/tests：

myapp-config-serviceさんbootstrap.ymlは次のとおりです。

spring: 
    application: 
     name: myapp-config-service 
    cloud: 
     config: 
      discovery: 
       enabled: true 

そしてmyapp-service-testさんapplication.yml：

eureka: 
    client: 
     serviceUrl: 
      defaultZone: http://${SERVICE_REGISTRY_HOST}:${SERVICE_REGISTRY_PORT}/eureka/ 
    instance: 
     preferIpAddress: true 

そしてmyapp-service-testさんbootstrap.yml：後

spring: 
    application: 
    name: myapp-service-test 
    cloud: 
    config: 
     discovery: 
     enabled: true 
     serviceId: myapp-config-service 

はdocker-compose.yml（ENV変数で置き換えられます起動時の実際の値）：

myapp-service-registry: 
image: myapp/myapp-service-registry:0.0.1 
ports: 
    - ${EUREKA_PORT}:${EUREKA_PORT} 

# myapp-config-service 

myapp-config-service: 
    image: myapp/myapp-config-service:0.0.1 
    volumes: 
    - ${MYAPP_DATA_FOLDER}/config:/var/opt/myapp/config 
    environment: 
     MYAPP_CONFIG_SERVICE_PORT: ${MYAPP_CONFIG_SERVICE_PORT} 
     SERVICE_REGISTRY_HOST: ${MYAPP_STAGING_IP} 
     SERVICE_REGISTRY_PORT: ${EUREKA_PORT} 
     MYAPP_CONFIG_SERVICE_GIT_URI: ${MYAPP_CONFIG_SERVICE_GIT_URI} 
    ports: 
     - ${MYAPP_CONFIG_SERVICE_PORT}:${MYAPP_CONFIG_SERVICE_PORT} 

# myapp-service-test 

myapp-service-test: 
    image: myapp/myapp-service-test:0.0.1 
    environment: 
    SERVICE_REGISTRY_HOST: ${MYAPP_STAGING_IP} 
    SERVICE_REGISTRY_PORT: ${EUREKA_PORT} 
    ports: 
    - ${MYAPP_SERVICE_TEST_TWO_PORT}:8080 

ブラウザをhttp://[...MACHINE-IP...]:8761/に接続し、ユーレカのダッシュボードを表示することで、ユーレカが動作していることを確認できます。同様に、私はconfigサービスが動作していることをテストし、http:///[...MACHINE-IP...]:8888/myapp-config-serviceに応答します。上記の構成では、一方で、次のログで、起動時にmyappのサービス・テスト・クラッシュ：

注私はユーレカ-最初のアプローチ（および設定spring.cloudを実装していない場合に。 configureをサービスのbootstrap.ymlに直接登録すると、サービスはEurekaに登録し、設定サーバーを見つけて正常に動作します（Eurekaのダッシュボードで登録済みのサービスが表示され、設定プロパティが正しく読み込まれているかどうかを確認できます）。

Answer 1

bootstrap.yml（およびconfigserverのサービスID）にeureka serviceUrlが必要です。
