Deploy Spring Eureka Service Registry on Azure with docker image

I created a Docker Image and loaded it via the docker hub. Then is tried to run it as a docker container and exposed the port 8080. The container is listed and the port column shows the following: 0.0.0.0:8080->8080/tcp.

So in my opinion the service is running but I cant access it with the ip-addres/eureka.

How is it possible to open the Eureka dashboard?

Edit: I changed the port and now the port column of the containers shows: 0.0.0.0:8761->8761/tcp

This is the log:

For your issue, you cannot access the container. As I know the possible reasons below:

  1. the container is not running well.
  2. the container is running well, but the application is not running well inside the container.
  3. both container and the application is running well, but you expose a wrong port. The port is not the one that the application listens to inside the container.

So you need to check it for the point above. And I find the default port is 8761 and you need to set the configuration. Take a look at the Containerize-Spring-Cloud-Eureka-Server.
