Overview

The following guide is designed to help you deploy an example app on Aptible. During this process, Aptible will launch containers to run a Python app with a web server, a background worker, a Managed PostgreSQL Database, and a Redis instance.

The demo app displays the last 20 messages of the database, including any additional messages you record via the “message board.” The application was designed to guide new users through a “Setup Checklist” which showcases various features of the Aptible platform (such as database migration, scaling, etc.) using both the dashboard and Aptible CLI.

Deploy App

Prerequisite: Ensure you have Git installed.

Using the Deploy Code tool in the Aptible Dashboard, you can deploy the Deploy Demo App. The tool will guide you through the following:

1. Deploy with Git Push

   
2. Add an SSH key

   

   If you have not done so already, you will be prompted to set up an SSH key.

3. Environment Setup

   

   Select your stack to deploy your resources. This will determine what region your resources are deployed to. Then, name the environment your resources will be grouped into.

4. Prepare the template

   

   Select Deploy Demo App for deployment, and follow command-line instructions.

5. Fill environment variables and deploy

   

   Aptible will automatically fill this template’s app configuration, services, and required databases. This includes: a web server, a background worker, a Managed PostgreSQL Database, and a Redis instance. All you have to do is fill the complete the environment variables save and deploy the code!

   Aptible will show you the logs in live time:

   
6. Expose your app to the internet

   

   Now that your code is deployed, it’s time to expose your app to the internet. Select the service that needs an endpoint, and Aptible will automatically provision a managed endpoint.

7. View your deployed app

   

   From here, you can optionally test the application’s message board and/or “Setup Checklist.”
