Deploy Spring boot api (Gradle) with MySQL to Synology

Hi,
Thanks for the great content here. I have NAS Synology DS220+ with DSM 7.2.1. I am trying to deploy my Spring boot (Gradle) api with MySQL to my Synology, but I don’t know how to do it.
I have created a jar file in my Intellij (./gradlew clean assemble) and now I want to make Image into Container Manager in my nas. Then to create container to connect with my MariaDB and to host the app. Can anyone help me and upload a video in youtube. It will be very helpful!
