同学你好，首先发现你这里有两个问题。
1、根据图1，你启动了三个eureka服务端的docker容器，但是这个三个eureka应用都是8080端口映射到宿主机的三个不同端口，这可能会导致你容器内eureka能启动宿主机却不能访问。
2、根据图3，你的eureka客户端中配置eureka服务端是用本地宿主机的局域网ip，按道理来说是可以的，但是docker和宿主机是网络隔离的，建议首先在启动eureka-server的docker容器的时候给容器用--name取别名，然后在eureka-client程序的配置文件中ip用hostname的方式去连接，最后启动eureka-client docker容器的时候用--link连接eureka-server容器。
若能解决你的问题，望采纳，若不能，请继续在该帖提出来。
