1- IDE

We prefer to use sublime/VS Code for development(you can opt for any IDE though, but that will mean no support from seniors for any issues relating it and that might lead to un-neccessary time waste thats why it is highly preferred to not use any other IDEs). You are encouraged to use sublime or VSCode.

Sublime:

Install Sublime3 (google or use this link) Here we will outline some basic configuration for sublime3 we usually use.

i- Settings Tweaks In sublime go to preferences->settings and place these in user settings tab along with other settings. Don't mess with default settings tab

#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)

My notes for Dokku on Digital Ocean.

These may be a bit outdated: Since I originally wrote them, I've reinstalled on a newer Dokku and may not have updated every section below.

Commands

Install dokku-cli (gem install dokku-cli) for a more Heroku-like CLI experience (dokku config:set FOO=bar).

# List/run commands when not on Dokku server (assuming a "henroku" ~/.ssh/config alias)

ssh henroku dokku
