Question: 1 / 400

What does the command 'docker pull' do?

Pushes a local image to a repository

Downloads a Docker image from a registry

The command 'docker pull' is specifically designed to download a Docker image from a registry, such as Docker Hub, to the local machine. This command allows users to retrieve pre-built images that can then be utilized to create containers. By specifying the image name, along with optional tags, users can control which version of the image they want to pull.

This functionality is vital for developers who need specific applications or operating systems encapsulated within Docker images, enabling them to set up environments or run applications without having to build images from scratch. It simplifies the workflow for retrieving necessary images, ensuring that development and production environments can be consistent and reproducible.
