Docker Tutorial for Beginners
Docker is a platform for developers and system administrators to develop, deploy, and run applications in containers. In this lesson, we will discuss the Docker architecture and how it works.
The Docker client talks to the Docker daemon, which does the heavy lifting of building, running, and distributing Docker containers. The client and the daemon can run on the same system, or the client can communicate with a remote daemon.
The Docker daemon runs on a host machine and manages Docker objects, such as images, containers, networks, and volumes. It is the most important component of the Docker architecture. The Docker daemon listens for Docker API requests and manages Docker objects in the background.
The Docker client is the primary way that Docker users interact with Docker. It sends commands to the Docker daemon using the Docker API, and displays the output to the user. The Docker client can communicate with the Docker daemon locally or remotely.
Docker registries are used to store Docker images. A Docker image is a template for a Docker container. Docker registries can be public or private, and Docker users can push and pull images from them. Docker Hub is the most popular public Docker registry.
Docker objects are the components that make up a Docker application. Docker objects include images, containers, networks, and volumes. Docker objects are created using the Docker API or the Docker CLI.
In summary, Docker architecture is based on a client-server model, with the Docker daemon doing the heavy lifting of building, running, and distributing Docker containers. The Docker client is the primary way that Docker users interact with Docker. Docker registries are used to store Docker images, and Docker objects are the components that make up a Docker application.
