我正在尝试部署可在我的本地主机上运行Web服务的Web应用程序。
我在dockerized属性文件中使用了端点url，并且正在使用host.docker.internal属性。

For example, I am trying to hit this service http://host.docker.internal:9002/custome/service. I am expecting this to be like http://localhost:9002/custome/service.



但是，我的日志中出现此错误

最佳答案

我遇到同样的问题，并解决了这个问题，删除了前缀http，例如:使用“host.docker.internal:9002 / custome / service”而不是“http://host.docker.internal:9002 / custome / service”。原因是

    # Added by Docker Desktop
    30.27.110.80 host.docker.internal
    30.27.110.80 gateway.docker.internal
    # To allow the same kube context to work on the host and the container:
    127.0.0.1 kubernetes.docker.internal
    # End of section

关于java - 引起原因:java.net.UnknownHostException:host.docker.internal，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51639790/
