Deploying to Heroku

gistfile1.txt

1. cd into root directory of app you want to push
2. add a Procfile if you haven't already, it tells heroku how to run your app
2. initialize a new git repsitory ( git init)
3. add the files in the git repository ( git add .)
4. commit the files in the git repository (git commit )
5. login to heroku if you haven't already (heroku login)
6. create a new heroku app (heroku create)
7. push from your current branch to heroku (git push heroku YOUR_BRANCH)
8. run any necessary app migrations (heroku run rake MIGRATION_NAME)
9. if anything fails, look in the heroku logs, google the errors and try again

common errors:

Problem: cannot find remote repository heroku

Solution: make sure you initialized a new respositroy with git init, and
created a heroku app with heroku create

Problem: Permission denied (public key)

Solution: try generating a new ssh key with 'ssh-keygen', then enter the command "heroku keys:add", add the key you just generating, try pushing again
__________________________________________________________

Problem: Cannot run migrations with 'heroku run rake'

Solution: make sure all your gems are accessible in the gemfile like 'rspec'

Problem: App was pushed and deployed but is showing an application error

Solution: makue sure you are specifying "ruby '1.9.3'" in the gemfile
___________________________________________________________

Problem: Anything else

Solution: look in heroku logs, fine where it crashed, google the error or go on stack overflow
