I thought I was going to use sqlite for my production database too, but after failing to get it working with dokku I opted for postgres.

To get Commit Redux online, I

• installed the postgres db service in dokku
• linked the service to the app
• created a seeds.rb file with a custom rake task
• ran migrations
• set domain and enabled lets encrypt
• reset the production db id sequence with a custom SQL query
• added user authentication
