Heroku makes deployment of arbitrary apps including Panel apps and dashboards very easy and provides a free tier to get you started. This makes it a great starting point for users not too familiar with web development and deployment.

To get started working with Heroku signup for a free account and download and install the CLI. Once you are set up follow the instructions to log into the CLI.

1. Clone this repository

2. Modify the Procfile which declares which command Heroku should run to serve the app. In this sample app the following command serves the iris_kmeans.ipynb example and the websocket origin should match the name of the app on Heroku app-name.herokuapp.com which you will declare in the next step:

web: panel serve --address="0.0.0.0" --port=$PORT iris_kmeans.ipynb --allow-websocket-origin=app-name.herokuapp.com

4. Create a heroku app using the CLI ensuring that the name matches the URL we declared in the previous step:

heroku create app-name

5. Push the app to heroku and wait until it is deployed:

git push heroku master

6. Visit the app at app-name.herokuapp.com

In order to serve your own app simply replace the iris_kmeans.ipynb with your own Jupyter notebook or Python file declaring a Panel app and then modify the Procfile to start that app instead.
