The brain of the Docker engine is the Docker Daemon, sometimes referred to as dockerd. It is in charge of running containers on a host machine and managing them. In this post, we’ll go in-depth on the Docker Daemon architecture, examining its essential elements and how they interact to make containerization possible. You will get insights into Docker’s fundamental features and be more prepared to optimise your containerized systems if you comprehend how Docker Daemon functions.
Docker Daemon Components: Docker Daemon comprises several key components, each playing a crucial role in the containerization process: a. REST API: Docker Daemon exposes a RESTful API that allows users to interact with Docker Engine programmatically. This API accepts HTTP requests and communicates with other Docker components to execute various actions, such as creating and managing containers. b. Image Service: The Image Service handles the management and storage of Docker images. It pulls, pushes, and stores Docker images from registries like Docker Hub or private repositories. The Image Service caches downloaded images locally to improve performance and efficiency. c. Container Runtime: The Container Runtime is responsible for creating, managing, and running…
