Docker Hub is a native Docker registry service which allows you to run pull
|
||||
and push commands to install and deploy Docker images from the Docker Hub.
|
||||
|
||||
Docker Cloud is built on top of the Docker Hub so Docker Cloud provides
|
||||
you with more options/features compared to Docker Hub. One example is
|
||||
Swarm management which means you can create new swarms in Docker Cloud.
