您的应用正在尝试使用名称jhipster-registry作为主机名来查找注册表.为此，您需要将注册表和应用添加到Docker网络.

Your app is trying to locate the registry using the name jhipster-registry as a host name. To be able to do that, you need to have your registry and app added to a docker network.

首先使用以下方法创建网络:

First create the network using:

docker network create my-network

通过给容器命名并将其添加到网络创建中来更新撰写文件:

Update the compose file by giving the container a name and adding it to the network create:

version: '2'
services:
    jhipster-registry:
        image: jhipster/jhipster-registry:v3.1.0
        volumes:
            - ./central-server-config:/central-config
        # When run with the "dev" Spring profile, the JHipster Registry will
        # read the config from the local filesystem (central-server-config directory)
        # When run with the "prod" Spring profile, it will read the configuration from a Git repository
        # See https://jhipster.github.io/microservices-architecture/#registry_app_configuration
        environment:
            - SPRING_PROFILES_ACTIVE=dev,native
            - SECURITY_USER_PASSWORD=admin
            - SPRING_CLOUD_CONFIG_SERVER_NATIVE_SEARCH_LOCATIONS=file:./central-config/localhost-config/
            # - GIT_URI=https://github.com/jhipster/jhipster-registry/
            # - GIT_SEARCH_PATHS=central-config
        ports:
            - 8761:8761
        networks:
            - my-network
        container_name: jhipster-registry


networks:
  my-network:
    external: true

运行应用程序时，请指定网络:

When running your application specify the network:

docker run --network=my-network ...

现在，您的应用程序可以使用jhipster-registry作为主机名与注册表进行通信.

Now your application can communicate with the registry using jhipster-registry as a hostname.
