Docker组合 – 无法在任何已知的服务器上执行请求
我有以下问题。 我有两个春季启动微服务（1.5.8版本），configuration服务和发现服务。 当我在本地运行它们时，服务正在启动并成功通信。
现在，当我使用docker撰写文件启动这两个服务时，出现以下错误：

发现服务：bootstrap.yml

我尝试了很多东西，但没有运气。 任何人都可以build议吗？
提前致谢
你已经尝试设置networking每个服务？ 所以，通过同一个networking服务config-svc和service discovery-svc通信。 尝试安装驱动程序bridge如下
version: '3.4' services: config-svc: image: "config-img" container_name: config-svc build: context: ../config dockerfile: docker/config.dockerfile expose: - "8888"
networks: - app-network discovery-svc: image: "discovery-img" container_name: discovery-svc build: context: ../discovery dockerfile: docker/discovery.dockerfile depends_on: - config-svc links: - config-svc:config-svc entrypoint: sh -c '/tmp/wait-for config-svc:8888 && java -jar discovery.jar' expose: - "8761" networks: - app-network networks: app-network: driver: brige
参考： https ： //docs.docker.com/compose/compose-file/
好的，我find了。 问题出在bootstrap.yml文件中的configuration服务中，spring.cloud.config.server.native.search-locations的属性值必须固定到classpath：configs。 现在它工作正常。
