  before_bundle_exec:
    - file:
        path: $home/config/multisite.yml
        contents: |
         multisite:
           adapter: postgresql
           database: discourse_rubyhub
           pool: 25
           timeout: 5000
           db_id: 2
           host_names:
             - rubyhub.store

  after_bundle_exec:
    - exec: cd /var/www/discourse && sudo -E -u discourse bundle exec rake multisite:migrate

Em vez de multisite dizia rubyhub em todo lugar, exceto no nome do arquivo de configuração .yml! Isso causou o erro!

Mas qual é a porta HTTP, ou como eu a altero no multisite para que eu possa configurar um proxy reverso adicional para rubyhub.store?
