Using a 3rd Party Registry
Quay.io is an example of a third-party registry.
Install a third party registry by logging in through your terminal and providing the third party url. For example:
$ docker login quay.io
Username ([your_username]): [your_username]
Password: [your_password]
Login Succeeded
You may need to reassign images with a new directory like so:
$ docker image tag [old_directory]/[image_name]:[tag] quay.io/[new_directory]/[image_name]:[tag]
Now you can push and pull using the third party registry:
$ docker image push quay.io/[new_directory]/[image_name]:[tag] # pushes to quay.io
$ docker image pull quay.io/[new_directory]/[image_name]:[tag] # pulls from quay.io
