How to Push Two Interconnected Images or a Yaml File to Docker Hub

Question

I'm an absolute beginner to docker hub and am trying to push two images to docker hub. One image is a MySQL database the other is a java war running on tomcat. The second image is an MVC application that links to the first.

I have tried searching for a solution without success.

Thank you,

Use the stock mysql image for the database; don't try to roll your own database container. Build a custom image (probably based on the stock tomcat image ) and push that to Docker Hub. Add the Dockerfile you used to build the image and the docker-compose.yml that drives the combined application to the root of your repository, next to your pom.xml file, and check them in to source control.

There's no way to push a Docker Compose YAML file or a "combination of multiple images" to Docker Hub in any form, only individual images, so those need to be stored separately.
