Packaging Spring Boot 3 as a JAR and Deploying to Docker Daemon & Docker Hub

Описание: In this tutorial, you will learn how to package a Spring Boot 3 project as a JAR file and deploy it to both a Docker daemon and Docker Hub. You'll explore the step-by-step process of containerizing your Spring Boot application, making it portable and easily deployable across different environments.

Starting from the basics, the tutorial will guide you through configuring your Spring Boot 3 project for packaging as a JAR file. You will then dive into Docker, learning how to set up a local Docker daemon and create a Dockerfile to define the container image for your application.

Next, you will discover how to build the Docker image and run it locally on your Docker daemon to ensure everything works as expected. The tutorial will cover best practices for configuring the Dockerfile and optimizing the image size.

Once the local testing is successful, the tutorial will shift focus to deploying the Docker image to Docker Hub, a popular registry for container images. You will learn how to create a Docker Hub account, tag the Docker image, and push it to Docker Hub for easy distribution and sharing.

By the end of this tutorial, you will have a solid understanding of how to package your Spring Boot 3 application as a JAR file, containerize it using Docker, and deploy it to both a local Docker daemon and Docker Hub. This knowledge will empower you to efficiently manage and distribute your applications in containerized environments.
