docker-compose and duplicator plugin from WordPress

Small video for those that wants to use docker or docker-compose with the Duplicator WordPress plugin, for local theme or plugin development.

I found my self facing the problem that I was helping a non-profit organization to update their WordPress theme and make small changes in the PHP, CSS code.

And I wanted to host it locally and test my changes, but they have the duplicator plugin installed and backups files from it.

The issue that I face was that I couldn't link the docker db service to the duplicators host input.

The first thing that I try was to bind my docker db service to my localhost, but there was just a small issue with that I have a small project running in the background for my to-dos and other personal things that use MySQL and the port was already in use do my docker-compose
Services didn't want to start because of the same port binding.

I was looking around for a better solution, then I remember that the WordPress service was in the same container as the db service.

So I just pass the service name to the duplicators input and that solve my problem.

But I look around, and I didn't find anything that could help me before, so that is why a make the video.

For the future me, I know that I will find this issue in the future
