How to dockerize your Spring Boot API | Docker Tutorial

A few weeks ago I created a video showcasing how we can set up a simple Spring Boot REST API, I now wanted to showcase how we can move this API into a Docker container and then run it.

IMPORTANT: OpenJDK is now deprecated and we should use "eclipse-temurin:17" instead. OpenJDK will still work but is not getting any new updates.

Note that the second line in the Dockerfile does not have any effect in this example; it merely searches for any JAR file, which can then be utilized, as the third line copies the JAR_FILE instead of directly placing the file.

My channel publishes programming and software engineering videos, especially Java and Python. If that is what you want, do not hesitate to join me on this journey!

Hi, when i open localhost:8000, nothing to show. But when i start application with Spring everythik work normal.Can help?

[viktormykhasko]

IMHO, the better idea is using JRE such as eclipse-temurin:17-jre-alpine instead of full JDK, the second line is useless or should be fixed and , maybe, from a security prospective - execute app in container as non root.

Hello! First of all Congratulation for your video!!

Well i have a problem, when i docker running this, it gives me an error messages about communication problem between the application and the MySQL database server.

Well the main error seems to be a "Communications link failure" with a "Connection refused" exception. I can understand that docker cant access my database server for some reason!.


I checked my database and everything is alright. Can you understand, why this is happening ?
