Process for deploying app on heroku

  1. sudo gem install heroku
  2. heroku create app_name
  3. git init
  4. git add ( add the files present in the app, see the files by ls command)
  5. git commit -m “commit the app”

  6. cd ~/.ssh (see that ssh directory exists or not)

     if exists then
   $ ls
   $ config id_rsa.pub
   $ id_rsa known_hosts
   $ mkdir key_backup
   $ cp id_rsa* key_backup
   $ rm id_rsa*--
 if "not exists" then
   $ ssh-keygen -t rsa -C "your email"
  7. heroku create
  8. heroku keys:add
  9. git push heroku master
  10. heroku rake db:migrate.

To see the error in opening the site in the browser

heroku logs --app app_name (run that command on the terminal)

if git push heroku master gives following error

------Agent admitted failure to sign using the key.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

then run this on prompt

ssh-add ~/.ssh/id_rsa
