DockerHub
DockerHub is a cloud-based registry service provided by Docker Inc. It is the default public container registry where you can store, manage, and distribute your Docker images. DockerHub makes it easy for other users to find and use your images or to share their own images with the Docker community.
Features of DockerHub
- Public and private repositories: Store your images in public repositories that are accessible to everyone, or opt for private repositories with access limited to your team or organization.
- Automated Builds: DockerHub integrates with popular code repositories such as GitHub and Bitbucket, allowing you to set up automated builds for your Docker images. Whenever you push code to the repository, DockerHub will automatically create a new image with the latest changes.
- Webhooks: DockerHub allows you to configure webhooks to notify other applications or services when an image has been built or updated.
- Organizations and Teams: Make collaboration easy by creating organizations and teams to manage access to your images and repositories.
- Official Images: DockerHub provides a curated set of official images for popular software like MongoDB, Node.js, Redis, etc. These images are maintained by Docker Inc. and the upstream software vendor, ensuring that they are up-to-date and secure.
To start using DockerHub, you need to create a free account on their website. Once you’ve signed up, you can create repositories, manage organizations and teams, and browse the available images.
When you’re ready to share your own images, you can use the docker command line tool to push your local images to DockerHub:
docker login
docker tag your-image your-username/your-repository:your-tag
docker push your-username/your-repository:your-tag
To pull images from DockerHub, you can use the docker pull command:
docker pull your-username/your-repository:your-tag
DockerHub is essential for distributing and sharing Docker images, making it easier for developers to deploy applications and manage container infrastructure.
