Discourse standalone docker installation exposed via socket. Nginx reverse proxy and Certbot set up outside.

Applying Updates

Ideally, updates should be applied via the admin interface. To update to the latest image run

sudo -s cd /var/discourse git pull ./launcher rebuild app

Certificates

To request a new certificate manually run

sudo certbot certonly --webroot -w /var/www/html -d forums.tropy.org

To renew

sudo certbot renew --deploy-hook "systemctl reload nginx"

Restoring Backups

Ensure that your backup file exists in

/var/discourse/shared/standalone/backups/default

To restore the backup

sudo -s
cd /var/discourse
./launcher enter app

And from inside the container

discourse enable_restore
discourse restore forums-tropy-org-YYYY-MM-DD-HHMMSS-vYYYYMMDDHHMMSS.tar.gz
discourse disable_restore

Back outside rebuild the instance

./launcher rebuild app
