Java Spring Cloud Cannot register any service to Eureka Server in Docker through docker-compose.yml

[datdatyul]

I'm trying to implement an example of **Spring Cloud** with its all services running in **Docker**.

I cannot register any service to **eureka server** as **eureka server** throws a connection issue in **Docker**.

When I show the **logs** of **eureka server** through this command (**docker logs <eureka-service-container-id>**), I got the error.

Here is the error shown below.

Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8761/eu
reka/}, exception=java.net.ConnectException: Connection refused (Connection refused) stacktrace=com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection
refused (Connection refused)

How can I fix that?

Here is **docker-compose.yml** shown below.
