Docker is an open-source platform that automates the deployment of applications inside software containers. One of the fundamental commands in Docker’s command-line interface is Before diving deeper into the The purpose of the The basic syntax of the command is:<\/p>\n The To illustrate the command’s functionality, let’s consider the following examples:<\/p>\n This command lists all currently running containers along with their Container<\/a><\/span>Containers are lightweight, portable units that encapsulate software and its dependencies, enabling consistent execution across different environments.
