java - Docker 启动非常慢并且使用 docker compose 收到异常

更新:当我使用网络并将它们一一链接并随后启动它们时，它工作得很好!使用docker-compose时它不起作用。

我正在使用eureka发现服务和zuul。我总共有 4 个微服务。一旦我启动它们，它们就会尝试在当时的 Eureka 服务上注册自己，但他们未能做到这一点。当他们尝试在eureka-service注册时，他们会遇到异常:请求执行错误(见下文)。一段时间后，他们在大多数情况下都会注册自己，但仍然不断抛出异常。

最佳答案

尝试将 Eureka 的 application.yml 更改为:

eureka:
  instance:
    hostname: localhost
    ip-address: 127.0.0.1
  server:
    enable-self-preservation: false
  client:
    registerWithEureka: false
    fetchRegistry: false
  serviceUrl:
    defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

就我而言，客户端部分如下所示:

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:9999/eureka/
instance:
  preferIpAddress: true

要记住的另一件事 - 即使您的 docker compose 文件中有“depends_on:”，Docker 也不会等待该容器中的服务实际可用，因此在 Eureka 客户端上看到很少的异常是正常的启动。如果觉得麻烦的话可以看看this
