#Goal Deploy your Rails App super easily with Dokku on Digital Ocean cheap cheap!

##Notes

• Follow 12 factor design (include the rails_12factor gem)
• Don't forget your Procfile with the command to start up your application server
• I prefer using external hosted logging services like Logentries (not in this guide)
• Set up performance monitoring AppSignal or New Relic (not in this guide)

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
