Spring Boot java.net.ConnectException：在Sping Boot 和Keycloak中使用docker-compose时连接被拒绝

我确实有几个Sping Boot 服务作为docker-compose文件的一部分。

字符串
我不知道为什么我会看到http://iam-service:8080/realms/OptionAdvisor/.well-known/openid-configuration": Connection refused。当我从另一个容器执行wget http://iam-service:8080/realms/OptionAdvisor/.well-known/openid-configuration时，我得到了预期的响应。当我在主机的浏览器中访问http://localhost:8080/realms/OptionAdvisor/.well-known/openid-configuration时，我也得到了预期的响应。
你有什么提示给我什么可能导致这个？下一步你会做什么来调试这个？
