I need help adding this container on to my docker-compose.yml

Hi!

Basically I just want to add this container:

https://hub.docker.com/r/coppit/no-ip/

On to the end of this compose file:

But unfortunately my attempts have failed. I want to try and keep the same folder structure as the compose file has gone with, so folders for “db”, “app”, “proxy” and then my new folder which I would call “noip”.

Would anybody be able to show me how I’d manage this?

Many thanks!
