What are Docker Image and Docker Hub?

The Docker Image is a set of files and a combination of parameters which will allow creating the instances to run in separate containers as an isolated process. The Docker hub is a kind of repository to the images where these images can be stored and this access is public. The Docker run command can be used to create the instance called container which can be run using the Docker image. Docker hub is the largest public repository of the image containers which is being maintained by the community of developers and individual contributors.
