# Based on: http://donpottinger.net/blog/2014/11/17/bye-bye-heroku-hello-dokku.html

# Add to gemfile:
ruby '2.1.2'
gem 'pg'
gem 'puma'
gem 'rails_12factor'
gem 'searchkick'
gem 'typhoeus'

# Create an initializer at 'config/initializers/typhoeus.rb':
require "typhoeus/adapters/faraday"
Ethon.logger = Logger.new("/dev/null")

# Install it
bundle install

# On config/database.yml set:
production:
  url: <%= ENV['DATABASE_URL'] %>
  
# On your app root folder create a file named 'Podfile' and write:
web: bundle exec rails s Puma -p 5000

# Push to your git at master branch

# Create droplet with Docker, do NOT check IPv6.
# Start with ssh key.

# Go to your DNS provider and setup it with your ip, be sure to set a CNAME with your default domaind and a subdomian wildcard.

# Go to youdomain.com
# Set your hostname and check "User virtualhost nameming for apps".

------------------------------
# if something goes wrong, you can delete that droplet and create a new one. If you have problems with:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!

# You can use:
ssh-keygen -R <server ip address or yourdomain.com>
------------------------------

# Login to server
ssh root@<ip address>

# Update Dokku
cd ~/dokku
git pull origin master
make install

# On your client computer at your app root folder:
git remote add dokku dokku@<server ip or youdomain.com>:<app_name>
# Example: git remote add dokku dokku@yourdomain.com:myapp

# Lets push to our server
git push dokku master  


# If something goes wrong, you can rollback with:
git remote rm dokku
