Working with Docker

Container technology is one of the most important advances in DevOps technology since the virtual machine. Docker and similar container technologies have revolutionized the way software applications are developed, deployed, and managed. Imagine containers as lightweight, standalone units that encapsulate all the necessary components to run an application, including code, runtime, system libraries, and settings. This encapsulation ensures that the application runs consistently across different environments, from a developer’s laptop to production servers.

Docker, in particular, is a widely used platform for building, shipping, and running containers. It provides a standardized way to package applications and their dependencies, isolating them from the underlying host system. This isolation enables developers to avoid the notorious “it works on my machine” issue, as containers behave consistently across various environments.
