‍

Docker Architecture

‍

‍

Docker's architecture is designed to facilitate the creation, deployment, and management of containerized applications. Here's an overview of Docker's architecture:

‍

Docker Daemon

The Docker architecture revolves around the Docker daemon (or Docker Engine), which runs as a background process on the host machine. The daemon is responsible for managing Docker objects such as images, containers, networks, and volumes. It listens for Docker API requests and handles container lifecycle management tasks, including container creation, starting, stopping, and removal.

‍

Docker Client

The Docker client is the primary interface through which users interact with Docker. It communicates with the Docker daemon via the Docker API, sending commands to the daemon to perform actions such as building images, creating and managing containers, networking, and more. The Docker client can be accessed through the command-line interface (CLI) using the docker command or through GUI-based tools.

‍

Docker Registries

Docker images are stored in repositories known as Docker registries. Registries can be public (like Docker Hub) or private, serving as repositories for Docker images that users can pull to their local machines or push their images to for sharing and distribution. Docker Hub is the default public registry provided by Docker, housing a vast collection of Docker images that are readily available for use.

‍

Docker Objects

Docker uses several types of objects to encapsulate and manage applications in containers:

‍

• Images: Docker images are read-only templates that contain application code, libraries, and dependencies required to run a containerized application. Images are created using a Dockerfile and can be stored in registries.

• Containers: Containers are lightweight, portable runtime instances of Docker images. They encapsulate applications and their dependencies, running as isolated processes on the host machine's operating system kernel. Containers can be started, stopped, and managed using Docker commands.

• Volumes: Docker volumes provide persistent storage for containers, enabling data to persist beyond the lifecycle of individual containers. Volumes facilitate data sharing and management between containers and the host system.

• Networks: Docker networks enable communication between containers running on the same host or across different hosts. Docker creates virtual networks that containers can connect to, ensuring secure and efficient communication while maintaining isolation.

‍

What Is Docker Deamon?

‍

‍

The Docker daemon, also known as Docker Engine, is a persistent background process that manages Docker containers on a host machine. It serves as the core of Docker's architecture, responsible for various essential tasks related to container lifecycle management and resource handling.

‍

Key functions of the Docker daemon include:

• Container Management: The daemon creates, starts, stops, and removes Docker containers based on commands received from the Docker client.

• Image Handling: It manages Docker images, which are templates used to create containers. This includes pulling images from registries (like Docker Hub), storing images locally, and building custom images using Dockerfiles.

• Networking: Docker daemon manages networks that allow containers to communicate with each other and with external networks. It creates virtual network interfaces for containers and facilitates network isolation.

• Storage Management: The daemon manages storage volumes used by containers for persistent data storage. It handles the creation, mounting, and deletion of volumes, ensuring data persistence across container restarts.

• Security and Resource Isolation: Docker daemon implements security measures to isolate containers from each other and the host system. It uses Linux kernel features (on Linux hosts) to provide process isolation and resource constraints, ensuring containers operate securely and efficiently.

• API Handling: The daemon listens for Docker API requests from the Docker client. It interprets API commands and performs the corresponding actions, such as starting a container or creating a new network.

‍

Overall, the Docker daemon plays a crucial role in enabling the creation, deployment, and management of containerized applications. It runs continuously in the background, facilitating seamless interaction between Docker clients and the underlying Docker infrastructure on the host machine.
