What Is Docker?

Docker overview

Let’s dive into some of the container tools, and the first is Docker. Imagine building our application, and writing our codes on frontend and backend, and then, it’s time to deploy the code or application on a different environment from our locals. This either breaks our CI/CD (continuous deployment/continuous integration) pipeline or takes lots of time to deploy, therefore it’s frustrating. And that’s where Docker comes in. Docker is a containerized platform or environment for packing, scaling, and shipping our application and code alongside its dependencies across multiple platforms that we intend to deploy or use in the same application.
