Docker Certified Associate Certification Training Course - Components of Docker Engine

The video tutorial explains the three main components of the Docker engine: the Docker Daemon, Docker REST API, and Docker CLI. It describes how these components interact to create, ship, and run container-based applications. The Docker Daemon acts as the server, the CLI as the client, and the REST API as the communicator. The tutorial also covers how containers are based on images from public registries like Docker Hub and how additional resources like networks and storage volumes can be created with containers. Finally, it delves into the processes of the Docker engine, detailing how instructions from the CLI are managed and executed.

Which component of the Docker engine acts as the client?

• Docker REST API

• Docker Hub

• Docker Daemon

• Docker CLI

What is the role of the Docker REST API?

• To execute commands

• To store images

• To manage storage volumes

• To facilitate communication between the CLI and the daemon

Where can Docker images be sourced from?

• Local storage

• Docker Hub

• Docker Daemon

• Docker CLI

What additional elements can be configured when creating a Docker container?

• Programming languages

• Operating systems

• User interfaces

• Networks and storage volumes

How does the Docker daemon process instructions?

• By sending them to Docker Hub

• By storing them for later use

• By receiving them from the CLI and processing via the REST API

• By directly executing them
