Create your own docker account.
Your Docker ID becomes your user namespace for hosted Docker services, and becomes your username on the Docker forums. To create a new Docker ID: Go to the Docker Hub signup page. Enter a username that will become your Docker ID.
We can consider Docker Hub as a service from Docker for locating and distributing containers for each image within the specified team. It is the most comprehensive repository of container images, with an order of all content sources, including open-source projects, developing the sharing of the application source code, and community developers using containers.
Let us work with Docker and Docker hub:

Yes, we able to pull the image from our own docker hub account.
Test with your own risk:
-- start all docker containers at one go
# docker start $(docker ps -a)
-- stop all docker containers at one go
# docker stop $(docker ps -a)
