Dockerizing Spring Boot Applications

Welcome to containerizing Spring Boot apps! Docker helps package your application into a standardized unit called a container.

Why is this great for Spring Boot?

• Portability: Run your app consistently anywhere Docker runs.
• Isolation: Your app and its dependencies are bundled together, avoiding conflicts.
• Consistency: The environment is the same from development to production.

Before we dive in, let's quickly define key Docker terms:

• Image: A lightweight, standalone, executable package that includes everything needed to run a piece of software, including the code, a runtime, libraries, environment variables, and config files. Think of it as a blueprint.
• Container: A runnable instance of an image. You can create, start, stop, move, or delete a container. It's the actual running application.
• Dockerfile: A text file that contains all the commands, in order, to build a given image.
