Components of Docker and its Brief Summary

the four main components of docker are:

• Docker client and server 
• Docker image 
• Docker registry 
• Docker container

 Docker client and server: The communication between the Docker client and the Docker host is via a REST API.

Docker image: A Docker image is a template that contains instructions for the Docker container. That template is written in a language called YAML, which stands for Yet Another Markup Language.

Docker registry: The Docker registry is where you would host various types of images and where you would distribute the images from.

Docker container: A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing.
