Containerize Spring Boot CRUD with Docker and Docker Compose

Overview

Class Central Tips

In this course, you will master Docker and Docker Compose to run Spring Boot applications and databases within containers. Initially, you will understand the necessity of executing apps in containers and familiarize yourself with Docker, Image, Container, Docker Hub, and Dockerfile. We will explore the benefits of using Docker, creating Dockerfiles, building Docker images, and launching containers. You will learn to convert a regular Spring Boot program into a Docker-based application, run databases within containers, and enable inter-container communication. Additionally, you will: - Check logs, manage images and containers - Create and utilize Docker Compose files to run multiple containers. - Cover creating Spring Boot applications using the Spring Initializer, - Understanding the Docker Hub, its repositories, images, and tags, and tagging Docker images to specific versions. - Build code, tag images, and push them to Docker Hub. By the end, you'll be proficient in building, running, and pushing containers to the central hub. This course is ideal for anyone interested in containers with basic Java and Spring Boot knowledge. This course is ideal for Java developers, DevOps engineers, and IT professionals looking to enhance their skills in containerization and microservices deployment. A basic understanding of Java, Spring Boot, and RESTful APIs is recommended.
