Satellite provides the ability to search repositories in Docker Hub/External Registries when one does Containers -> New Container -> <select compute resource> -> Docker Hub/External registry

This functionality could be ideally leveraged in the following workflow
1) Content -> Products
2) Click on Repo Discovery (or may be a new one for Docker Repos),
3) Use the Docker Hub/External Registry to search repositories in those registries (output like -> https://hub.docker.com/search/?isAutomated=0&isOfficial=0&page=1&pullCount=0&q=busybox&starCount=0 )
4) Have the user select the repository they want from the search. They select the product and click "Create Selected"
5) New Repositories created in Library.'



Potential Issues
1) Search likely requires V1 support in Docker Hub/External Registries since that endpoint is not supported in V2 registries
2) The search results contain minimal information, like the a 40 character description, and the repo owner. We may want to provide the user the url on the repo specs in docker hub
