How to Completely Remove Seafile Docker And Start from Scratch?

I’m on Ubuntu, and I’d like to completely remove everything related to Seafile docker, and start from scratch.
I tried the following, but /opt/seafile-data/nginx/conf/ is empty.

docker-compose down
sudo rm -rf /opt/seafile*
sudo rm -rf /opt/container*
docker-compose rm -v -f
docker-compose up

Thanks for your help!

This worked for me.
Warning: It’ll remove all the containers.
docker rm $(docker ps --filter=status=exited --filter=status=created -q)
