How to use docker-compose with with tomcat

Question

I am trying to set up a tomcat server. I need to edit some of the files within the docker container and want to know is there a way I can save these files so that if we're to do docker-compose up again on another machine it was used the edited files? One idea I had was to take the tomcat image to modify it then use the custom image in docker-compose. Or am I just overthinking this and having the edit those files manually is something that I just have to do. Also, I am relatively new to docker so any advice would be helpful.

Using your own custom version of the tomcat image is the simplest way to configure it to your specifications.

See for instance, as example of configurations:

• "Docker tomcat editing configuration files through dockerfile"
• "How to change user config in docker tomcat 8?"
