Which components make up the Docker architecture?

The correct choice identifies the key components of Docker architecture, which includes the client, Docker host, and Docker registry.

In this architecture, the client acts as the main interface through which users interact with Docker. It sends commands to the Docker daemon (or Docker host) to create, manage, and manipulate Docker containers. The Docker host is where the containers run, and it includes the Docker daemon, which is responsible for the actual creation and management of containers, images, and networks.

The Docker registry is essential for storing Docker images. It serves as a repository where users can upload and download Docker images, making it easier to share images among different environments or teams.

This combination of components facilitates a robust and efficient system for containerization, allowing for easy deployment and scaling of applications. In this context, recognizing the roles of the Docker host and registry within the Docker ecosystem is crucial for managing containerized applications effectively.
