Docker, the leading containerization platform, offers a wide range of commands to manage and orchestrate containers efficiently. 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:

docker run -d -p 80:80 nginx

Listing Containers: To view the active containers, utilize the ps command:

docker ps

Stopping a Container: To stop a running container, employ the stop command followed by the container ID or name:

docker stop <container_id or container_name>

Removing a Container: To remove a stopped container, use the rm command followed by the container ID or name:

docker rm <container_id or container_name>

Docker Volume Commands:

Creating a Volume: To create a volume for persistent data storage, execute the volume create command:

docker volume create <volume_name>

Listing Volumes: To view the existing volumes, use the volume ls command:

docker volume ls

Removing a Volume: To remove a volume, employ the volume rm command followed by the volume name:

docker volume rm <volume_name>

Docker Network Commands:
