Deploy To Heroku

You'll need roughly 4 minutes to read this article.

Codeship makes it easy to deploy your application to Heroku using Codeship’s integrated deployment pipelines.

Setup Heroku Deployment

Step 1 - Navigate to Deployment Configuration

Navigate to your project’s deployment configuration page by selecting Project Settings > Deploy on the top right side of the page.

Project Settings Deployment

Step 2 - Add New Deployment Pipeline

Edit an existing deployment pipeline or create a new deployment pipeline by selecting + Add new deployment pipeline. Create the deployment pipeline to match the exact name of your deployment branch or a wildcard branch.

Create branch deploy

Step 3 - Heroku

Select Heroku

Select Heroku

Step 4 - Deployment Configuration

Configure Heroku

Application Name

Insert the name of the Heroku application you want the pipeline to deploy to.

Heroku API Key

In order for you to deploy your app using Codeship, you need to provide the Heroku API key from your Heroku account. You can access your Heroku API key here.

Push A Build

Heroku Success

You have now successfully setup deployment to Heroku. Go ahead and push a commit to your configured deploy branch.

Additional Configuration Settings (optional)

You can configure additional settings to your Heroku deployment by selecting More Options:

Select Heroku Deploy Options

Heroku Deploy Options


After each deployment, we check your application to make sure that it is up. We will either call the default * URL or the URL you specified here.

If this URL requires basic auth please enter: http://YOUR_USERNAME:YOUR_PASSWORD@YOUR_URL


This takes a different Heroku app and will restore the database of the current Heroku application you are deploying to with the main database from the Heroku application posted here.

Backup Database

Backup your database before you deploy. See Heroku’s Creating a Backup page for more information.

Force Push

This causes git to disable some checks and can cause the remote repository to lose commits. Use this option with care.

See git push -f for more info.

Post-deploy Command

You can specify a command to run post-deployment. The dynos will be restarted after running. This can be useful for running migrations or other commands that need to be run on each deploy.

Check app URL

This will enable your build to check the URL of your application to make sure that it is up.


Missing SSH Key

The public SSH key for your Codeship project should automatically get added to Heroku when you setup the deployment. If the key is missing or incorrect you may see an error like this during the git push step of the deploy:

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

To fix this issue, get the public SSH key for your project under Project Settings > General and add it to Heroku.

SSH Key is Already in Use

During a Heroku deployment you might encounter this error on the step that syncs your project’s SSH key to Heroku:

This key is already in use by another account. Each account must have a unique key.

To fix this issue, visit Project Settings > General and click Reset project SSH key. This will reset the SSH key for the project and add the new key to the repository on your SCM. The next time you deploy the new SSH key will automatically sync to Heroku.

check_url fails for Heroku deployment

After each deployment we check if your app is up. Therefore we call (wget) either the default * URL or the URL you specified here.

If the build fails during check_url YOUR_URL it’s usually because your application does not respond with a HTTP/2xx status code at the URL you provided (or the default URL for the deployment if you didn’t provide any).

To solve this, you can:

  • Respond with a HTTP/200 status code at the root of your application.

  • Configure a URL that will respond with such an status code in the advanced deployment configuration.

Note that you can disable the check URL functionality by unselecting the “Check app URL” option on the deployment configuration.
