[git] How to link a folder with an existing Heroku app

I have an existing Rails app on GitHub and deployed on Heroku. I'm trying to set up a new development machine and have cloned the project from my GitHub repository. However, I'm confused as to how to link this folder up to Heroku. Originally, I used the heroku create command, but obviously I don't want to do that this time since it will create another Heroku instance.

You should probable start ssh-agent and add your keys. Check this,

It helped me.

I've my project in github and heroku, for upload an heroku use :

heroku git:remote -a <project>

The doc it is:

https://devcenter.heroku.com/articles/git

Don't forget, if you are also on a machine where you haven't set up heroku before

heroku keys:add

Or you won't be able to push or pull to the repo.

The Heroku CLI has an easy shortcut for this. For an app named 'falling-wind-1624':

$ heroku git:remote -a falling-wind-1624
Git remote heroku added.

See https://devcenter.heroku.com/articles/git#creating-a-heroku-remote

for existing repository

type in terminal

$ heroku git:remote -a example

Use heroku's fork

1. Use the new "heroku fork" command! It will copy all the environment and you have to update the github repo after!

   heroku fork -a sourceapp targetapp
   

2. Clone it local

   git clone [email protected]:youamazingapp.git
   

3. Make a new repo on github and add it

   git remote add origin https://github.com/yourname/your_repo.git
   

4. Push on github

   git push origin master
   

Two things to take care while setting up a new deployment System for old App

1. To check your app access to Heroku (especially the app)

heroku apps

it will list the apps you have access to if you set up for the first time, you probably need to

heroku keys:add

2. Then set up your git remote

For already created Heroku app, you can easily add a remote to your local repository with the heroku git: remote command. All you need is your Heroku app’s name:

heroku git:remote -a appName

you can also rename your remotes with the git remote rename command:

git remote rename heroku heroku-dev(you desired app name)

then You can use the git remote command to confirm that a remote been set for your app

 git remote -v

heroku login 

git init

heroku git:remote -a app-name123

then check the remote repo :

git remote -v
