Panel#

Ploomber Cloud supports Panel. For information on how to develop Panel apps, please check the documentation.

To deploy an app, first create an account.

Once you have an account, you need at least two files:

  1. Your application file (app.py)

  2. A dependencies file (requirements.txt)

Note that the application will run with Python 3.11. Refer to this section for customized deployments. Here is a sample Docker-based Panel application.

Application file#

Your app.py must be a Panel application. An example is available here.

Dependencies#

To deploy a new project, list your dependencies in a (requirements.txt). For example, if you’re using JupySQL, pandas and matplotlib, your requirements.txt file will look like this:

# sample requirements.txt
jupysql
pandas
matplotlib

Testing locally#

To test your Panel app, create a virtual environment and install the packages:

pip install -r requirements.txt

Then run the following command to start the application:

panel serve app.py

Deploy#

Deploy from the menu

Once you have all your files, create a zip file.

To deploy a Panel app from the deployment menu, follow these instructions:

Try an example

To download and deploy an example Panel application start by installing Ploomber Cloud and setting your API key:

If you don’t have an API key yet, follow the instructions here.

Now, download an example. It will prompt you for a location to download the app. To download in the current directory, just press enter.

Note

A full list of Panel example apps is available here.

You should see a confirmation with instructions on deploying your app. Now, navigate to your application:

cd location-you-entered/data-viz

Deploy from the CLI

Initialize and deploy your app with:

ploomber-cloud init
ploomber-cloud deploy --watch

Tip

To ensure your app doesn’t break on re-deployments, pin your dependencies.
