What is Docker Hub?

Docker Hub is a service provided by Docker, Inc. that allows users to store and share Docker images.

Key Features of Docker Hub:

  • Image Repository: Docker Hub acts as a vast repository where users can upload and download Docker images. These images can be official images provided by Docker or community-contributed images.
  • Public and Private Repositories: Users can create both public and private repositories. Public repositories are accessible to anyone, while private repositories require authentication.
  • Automated Builds: Docker Hub can automatically build images from source code stored in repositories like GitHub or Bitbucket.
  • Webhooks: Docker Hub supports webhooks, which can trigger actions when an image is pushed to a repository. For example, a webhook could trigger a continuous integration pipeline.
  • Organizations and Teams: Docker Hub allows users to create organizations and teams to manage access to private repositories.
