What Is Docker?
Explore the fundamentals of Docker, a container platform that packages applications and their dependencies for consistent deployment. Understand Docker engine components, Docker objects like images, containers, and volumes, and basic command usage. This lesson equips you with foundational knowledge to deploy scalable and portable applications efficiently across environments.
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.
The beauty of Docker is that we get to do those as mentioned above quickly, producing a lightweight executable image that can be deployed on any environment or server easily.
