Docker Crash Course #4 - Parent Images & Docker Hub

Description: In this video, you will learn about the concept of parent images and how to use Docker Hub, the public registry for Docker images. What are parent images? A parent image is the base image that a new Docker image is built upon. The parent image provides the basic operating system and runtime environment for the new image. This allows you to reuse common components and avoid having to package everything from scratch. What is Docker Hub? Docker Hub is a public registry for Docker images. It is the largest repository of Docker images in the world, with over 180,000 images available. Docker Hub allows you to find, pull, and share Docker images. How do parent images and Docker Hub work together? When you create a new Docker image, you can specify a parent image. The new image will inherit all of the files and configurations from the parent image. This can save you a lot of time and effort, as you only need to add the files and configurations that are specific to your application. You can also use Docker Hub to find and pull parent images. Docker Hub has a search engine that you can use to find images, and you can also browse images by category. Once you have found an image that you want to use, you can pull it to your local Docker environment. What you'll learn:
