Hey Kevin - thanks for the tutorial, it's really helpful for the project I'm trying get off the ground.

I'm having a bit of an issue when it comes to building the docker image, and I'm not sure if it's because the openjdk:alpine19 image you listed is deprecated or not.

./mvnw clean package -DskipTest &&
docker compose build --no-cache &&
docker compose up -d

Is returning

[+] Building 0.8s (3/3) FINISHED

Any help here would be much appreciate, thank you!

Hello Diego,

I didn't encounter this problem during my local development, but there are some people who apparently faced the same problem online,

I suggest you to try one of these 3 methods:

• Change the name of your docker file and start it with capital D. example: spring.Dockerfile or Dockerfile.spring
• Update your Docker application on your workstation
• Restart your Docker application on your workstation

Here are links to more information about your problem:

• https://stackoverflow.com/questions/64985913/failed-to-solve-with-frontend-dockerfile

I hope I helped you mate

Hey, thank you for the response.

It appears that since I am running on an Apple Silicon Machine, which cannot natively run x86 images, and that there is no arm64 version of the image - docker was unable to download it.

I'm going to setup a remote development environment running x86 and see if that solves my issue.

Thanks again - Diego

It's weird, I'm using an Apple Silicon M2 Mac Mini, and I have not faced this issue.

Hi,

I followed this (am new to java, but old to programming) and well....

15/02/2024 11:05 - Build completed with 47 errors and 0 warnings in 2 sec, 93 ms

There's so much that isn't covered here - doesn't seem like all the necessary dependencies are in place for example.

Have you tried following this guide verbatim? I have all the code in place and did everything that is stated - but many things must be missing.

Take care

Hi @etelect-sorlim,

I tried the tutorial myself, and everything works well. you can find the full source code here on my github. :)
