To reset the configuration and data, remove the Docker containers, Docker volumes and the generated deploy/config files.
docker compose down --volumes
rm -vf config/{LocalSettings.php,wikibase-php.ini,wdqs-frontend-config.json}Removing the traefik-letsencrypt-data volume will request a new certificate from LetsEncrypt on the next launch of your instance. Certificate generation on LetsEncrypt is rate-limited; eventually you may be blocked from generating new certificates for multiple days. To avoid that outcome, change to the LetsEncrypt staging server by appending the following line to the traefik command stanza of your docker-compose.yml file:
--certificatesresolvers.letsencrypt.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory
