Creation of Dockerhub account

Docker Hub: It is a service provided by Docker for finding and sharing container images with our team. Key features include: Private Repositories: Push and pull container images. Automated Builds: Automatically build container images from GitHub and Bitbucket and push them to Docker Hub.

Users get access to free public repositories for storing and sharing images or can choose a subscription plan for private repositories.
