pushing into heroku repo

Question

I am currently learning how to use Heroku and I'm having a bit of trouble.

When I type the commands

    git push heroku master

I get the message

    Warning: Permanently added the RSA host key for IP address '50.19.85.156' to the list of known hosts.
    Permission denied (publickey).

I currently have git set up on my computer with RSA key added for my machine.

I'm assuming there is a separate RSA key that I need to add to my heroku account? I'm not entirely sure.

*** EDIT * ** * ** * ** * ***

I found out what was wrong. I needed to add my key

    heroku keys:add ~/.ssh/id_rsa.pub

However, I am having another problem now.

Basically, I created an rails app I wanted to upload but I deleted it on my heroku account. I created another app and I want to use this app. However when I

    git push heroku master

I will get the message

    No such app as rocky-gorge-9306 

Where rocky-gorge-9306 is my previous app, not the new one that I create

When I enter the command

    git remote -v

I get

    heroku  git@heroku.com:rocky-gorge-9306.git (fetch)  <---- old deleted app that does not exist 
    heroku  git@heroku.com:rocky-gorge-9306.git (push)
    origin  https://github.com/liondancer/first_app.git (fetch)
    origin  https://github.com/liondancer/first_app.git (push)

Answer 1

I assume, you have public/private keys on your development machine. If not, do the following:

ssh-keygen -t rsa

Heroku configuration

1. Install Heroku Toolbelt
2. Configure your Heroku account: heroku login
3. Verify, your git heroku configured properly: git remote -v . If not, do the following: heroku git:remote -a your_heroku_app_name
4. Now you should be able to push to heroku: git push heroku master
