Working with git remotes on Heroku
Generally, you will add a git remote for your Heroku app during the Heroku app creation process, i.e.
heroku create. However, if you are working on an existing app and want to add git remotes to enable manual deploys, the following commands may be useful.
Adding a new remote
Add a remote for your Staging app and deploy
Note that on Heroku, you must always use
master as the destination branch on the remote. If you want to deploy a different branch, you can use the syntax
local_branch:destination_branch seen below (in this example, we push the local
staging branch to the
master branch on heroku.
$ git remote add staging https://git.heroku.com/staging-app.git $ git push staging staging:master
In some cases, your local branch may be missing some commits that were already deployed to Heroku, resulting in an error. If you are very sure you want to proceed, add the
$ git push staging staging:master -f
Add a remote for your Production app and deployu
By convention, the remote name "heroku" is typically used for the production application.
$ git remote add heroku https://git.heroku.com/app.git $ git push heroku master
Add a remote via Heroku CLI
As @voke points out, you can alternatively use a Heroku CLI command to add your remote. However, it looks like this will always use the default remote name
heroku for the remote. If you would like to use a different name for your remote, see the "Rename a remote" section below.
$ heroku git:remote -a staging-app
Edit: Thanks to @nruth for pointing out you can supply a remote name to this command with the
$ heroku git:remote -a staging-app -r staging
Add a remote using the SSH protocol
As @Saworieza points out, all of the examples above use the https protocol for connecting to the remotes, but it is also possible to connect via ssh.
$ git remote add staging firstname.lastname@example.org:staging-app.git $ git remote add heroku email@example.com:app.git
Other useful commands
List your git remotes
$ git remote -v
Rename a remote
$ git remote rename heroku staging
Change a remote URL or protocol
If you have already created https remotes and want to switch them to use ssh, the following command can be used. This command can also be used to change the target URL without changing the protocol
$ git remote set-url staging firstname.lastname@example.org:staging-app.git $ git remote set-url heroku https://git.heroku.com/production-app.git
