Docker image ran successfully but application didn't run

I have created a docker image for deployment of microservice.

I am right now testing ti by trying to deploy on my local machine.

The docker container ogt created successfully and I am getting started application

But when I try to hit any rest service like so localhost:8080/myApi/test
It gives me error 

 localhost refused to connect.
Search Google for localhost 8080 payment
ERR_CONNECTION_REFUSED

What could possibly be going wrong ?

Checking list of running images docker ps gives me an entry with empty port details .Could this be the reason ?

Solution

  • To access services inside containers you need to forward host ports to container ports.

    It can be done with -p HOST_PORT:CONTAINER_PORT parameter in the command line.

    docker run -it -p 8080:8080 test_3
