deploy on heroku

Pre-requisites

Go to heroku.com and create a new account. The Heroku username should be given permissions.(need info)
Install heroku toolbelt from https://toolbelt.heroku.com/ (this should automatically install git also)

Test the tool belt installation by opening a command prompt typing git --version and after that heroku version.

Create 3 separate directories: "work", "test" and "production".

"work" contains all the source code from Github.
"test" contains all the sources that will be deployed to the Heroku test environment - http://carmindz-test-on-heroku.herokuapp.com/. To avoid unwanted problems, before pushing to production, always push here first.
"production" contains all the sources that will be deployed to production. The app deployed here will be visible on carmindz.in. Hence pushing to production requires exercising caution.

Make sure all changes that need to be deployed are pushed to Github.
Open command prompt and navigate to "test" folder.
git clone https://github.com/Coena/carmindz-heroku.git. This requires Github authentication. The latest code(along with the changes to be deployed) is obtained when cloning.
When cloning is done, cd into the carmindz-heroku directory, and type git remote -v It should display: origin https://github.com/Coena/carmindz-heroku.git (fetch) origin https://github.com/Coena/carmindz-heroku.git (push)
git pull origin [branch]. Specify the branch that contains the changes to be deployed
When pull is done, type, git remote add heroku git@heroku. com:carmindz-test-on-heroku.git
After creating the remotes for heroku, typing git remote -v should display heroku git@heroku.com:carmindz-test-on-heroku.git (fetch) heroku git@heroku.com:carmindz-test-on-heroku.git (push) origin https://github.com/Coena/carmindz-heroku.git (fetch) origin https://github.com/Coena/carmindz-heroku.git (push)

Pushing the changes to Heroku is done using git push heroku master

When pushing for the first time, ensure that your keys are already on Heroku. If you haven’t already uploaded them, run ssh-keygen -t rsa to generate the keys
heroku keys:add <file_path> uploads the keys
git push heroku master pushes all the changes to the Heroku test environment
A push to heroku might require that a `heroku pull origin master' be executed first if source already deployed has to be merged with the one in Github.
The updated application can be accessed from http://carmindz-test-on-heroku.herokuapp.com/

Subsequent updates to heroku test environment can be done using git pull origin and git push heroku
