Docker コンテナーで JHipster レジストリーを実行しています。Docker で実行されているすべてのアプリケーションは、レジストリ エンドポイント (ポート 8761) に接続して登録できます。

しかし、IDEA で実行されているアプリケーションに接続しようとすると、レジストリ エンドポイントに接続しようとするとエラーが発生します。

アプリケーションは Register に接続します (ログに表示されます) が、その後、次のエラーが表示されます。

UnknownHostException: registry

docker で実行されているレジストリに接続する方法を知っている人はいますか?

私の春のapplication.ymlは次のとおりです。

eureka:
    instance:
        prefer-ip-address: true
    client:
        enabled: true
        healthcheck:
            enabled: true
        registerWithEureka: true
        fetchRegistry: true
        serviceUrl:
            defaultZone: http://admin:admin@localhost:8761/eureka/

jhipster-registry のデフォルト ゾーンはhttp://user:pass@register:8761/eurekaです。

localhost に変更すると、次のようになります。

eureka:
    client:
        serviceUrl:
            defaultZone: http://admin:admin@localhost:8761/eureka/

動作しますが、この場合、docker で実行されているサービスはレジストリにアクセスできません (逆の問題)。

ありがとう！

同様の問題がありました。3.5.0 では、docker ベースのレジストリーを正常に開始でき、その後、docker 以外のバージョンのマイクロサービスとゲートウェイを開始できました。3.5.1 では、それができなくなり、同じエラーが発生しました。https://github.com/jhipster/generator-jhipster/pull/3848に関連していると思います。いずれにせよ、/etc/hosts ファイルにエントリを追加し、「レジストリ」が 127.0.0.1 を指すようにしました。
