In this blog post, we will explore the most essential Docker commands and provide practical examples to demonstrate their usage. Whether you're a beginner or an experienced Docker user, this comprehensive guide will help you master Docker commands and enhance your container management skills.

Docker Image Commands:

Pulling an Image: To download an image from a registry, use the pull command. For example, to pull the official Ubuntu image, execute the following command:

docker pull ubuntu

Listing Images: To view the list of downloaded images, employ the images command:

docker images

Removing an Image: To remove an unwanted image, use the rmi command followed by the image ID or name:

docker rmi <image_id or image_name>

Docker Container Commands:

Running a Container: To start a container from an image, use the run command. For instance, to run a basic Nginx web server container, execute the following command:
