I followed this tutorial to set up with success a multisite install with Docker. I recently ran into an error when trying to upgrade and I believe the line:
- exec: cd /var/www/discourse && sudo -E -u discourse bundle exec rake multisite:migrate
Should be edited to:
- exec: cd /var/www/discourse && sudo -H -E -u discourse bundle exec rake multisite:migrate
Could anyone confirm/edit the tutorial?
