# Docker Hub Repository

This tutorial explains to you what is the Docker Hub Repository. At the end of this article you will understand what the Docker Hub Repository is.

If you want to create a Docker container on which you want to deploy something, you need to have a Docker image. A Docker image is a template used to create and launch a Docker container. A Docker image can contain a simple Linux installation or fully-configured enterprise software install, ready to run. In order to understand better how Docker is working, you can take a look at the article named What is Docker .

On the Internet we can find a lot of Docker images and most of them we can find on the Docker Hub. Docker Hub is a registry service on the cloud that allows you to download Docker images that are built by other communities.

If you want to search for images into the Docker Hub, you can run the docker search command:

The Docker Official Repositories are a curated set of Docker repositories hosted on Docker Hub.

They are designed to:

• Provide essential base OS repositories (for example, ubuntu, centos) that serve as the starting point for the majority of users.

• Provide drop-in solutions for popular programming language runtimes, data stores, and other services, similar to what a Platform-as-a-Service (PAAS) would offer.

• Exemplify Dockerfile best practices and provide clear documentation to serve as a reference for other Dockerfile authors.

• Ensure that security updates are applied in a timely manner. This is particularly important as many Official Repositories are some of the most popular on Docker Hub.

If you want to pull a specific image from the Docker Hub, you can run the docker pull command:

After that you can use the docker images command in order to see that the new image is in the local repository.

Enjoy working with Docker images and Docker containers !
