The Docker Technology

The Docker platform is designed to make building, shipping, and running containers as easy as possible.

Docker’s high-level components

At a high level, there are two major parts to the Docker platform:

• The CLI (client)
• The engine (server)

The CLI is the familiar docker command-line tool for deploying and managing containers. It converts simple commands into API requests and sends them to the engine.

The engine comprises all the server-side components that run and manage containers.

The below figure shows the high-level architecture. The client and engine can be on the same host or connected over the network.
