Docker run connectionError - docker

Question

Here is my first attempt to use Docker image to implement Spring Boot app that users Active directory for authentication.
So, I have a Docker image of active directory, downloaded from Docker https://hub.docker.com/r/clcmanagedos/active-directory-services/.
when i try to run the docker image, it throws a Exception.
$ docker images
