An Overview of Docker Architecture
What is Docker?
An open-source platform for developing, building, and running applications. It enables apps to be packaged and run within a loosely isolated environment known as container.
It interacts with multiple daemons through a host, which may or may not change over time. Also generates CLI to send commands and interact with the daemon.
1. Docker Client
2. Docker Host
Docker hosts enable the execution and running of container-based applications. It facilitates management of images, containers, networks, and storage volumes.
3. Docker Registry
A service or facility that permits the storage and retrieval of images as required. There are two types of registries: public registries (Docker Hub) and private registries.
4. Docker Objects
Docker environment consists of images, containers, networks, volumes, plugins, and other objects.
