So i can change the dockerfile accordingly to copy my version of una in to be deployed instead?

Lets say i do not want to download the trident but instead copy the una i currently have to the docker image what other potential settings do i need to take note of or change and for an instance how do i run the app and sql in the docker file do u have the command to do it? I was looking at the dependencies UNA would need before and this dockerfile is really helpful in that aspect which I would like to thank you. What are the potential fields to change to use my own application instead of downloading as well as how do i run the application or databases such as the UNA is running. May I know as well if there are any changes in the dependencies?
