docker - jhipster 在开发过程中提供单独的服务

Question

目标

我们想创建一个开发环境，在其中我们可以在服务器上运行最新版本的注册表、UAA 和网关。然后，我们想在本地开发和运行（在 docker 内部或外部）一个微服务。然后应该将此微服务配置为连接并与其他服务器通信。

测试设置

我现在已经通过 jhipster 子生成器为我们的网关、uaa 和注册表生成了一个 docker-compose。然后我尝试通过 gradlew 启动我目前正在开发的微服务，通过 gradlew dockerBuild 构建它并启动 app.yml。我还尝试将 app.yml 中的主机名更改为 localhost、127.0.0.1 和注册表 docker 容器的 IP。

我的结果

• 如果主机名是 jhipster-registry：unknownhostexception。很可能是因为应用程序是在不同的 docker-compose 文件中启动的。
• 如果主机名是 localhost 或 127.0.0.1：http://127.0.0.1:8761/config/application/prod/master连接被拒绝。更改为 也许需要更多配置？
• 如果主机名是注册表 docker 容器的 ip：在终端中 jhipster 标志之后没有给出其他输出。但是应用程序永远不会因为异常而停止。
