How do I delete the Speech and do an installation from scratch, everything fresh and clean?
Sorry for my English, as I delete the current Discouse, and install a new one
Is this what you need? discourse/INSTALL-cloud.md at main · discourse/discourse · GitHub
If you want to delete all data and start over you can do this:
cd /var/discourse ./launcher destroy app rm -r shared/standalone ./launcher rebuild app
If you are going to do it often you might delete just the postgres_data directory, but this should do it.
