Getting Started with Inspira on Render

This guide will demonstrate how you can deploy Inspira applications on Render.


Before proceeding with this tutorial, it is essential to read the How To Use a PostgreSQL Database in a Inspira Application guide.


When we put our application into action for real use, we'll use Gunicorn along with Uvicorn workers to make it work smoothly.

$ pip install gunicorn

Configuration Update

Please open the file and modify its content to match the following configuration:

import os

from inspira.config import Config

config = Config()

config["SECRET_KEY"] = os.environ.get("SECRET_KEY", "my-dummy-secret-key")

uri = os.environ.get("DATABASE_URL", "no-db")

if uri.startswith("postgres://"):
    uri = uri.replace("postgres://", "postgresql://", 1)


We are replacing postgres with postgresql because SQLAlchemy has removed support for the postgres name.
You can also change the DATABASE_URL in the settings of the app under Environment and redeploy the app.

Update to Main File

Open and modify it as shown below:

from inspira import Inspira

from config import config

app = Inspira(config=config)

The secret_key has been removed and replaced with config since the secret_key is now included in the config file.


To initiate the creation of the user table, execute the following command to generate a migration file:

$ inspira new migration create_table_users

This command will create the migration file in the migrations folder. Open the file and make the necessary modifications as shown below:

    name VARCHAR(50), 
    email VARCHAR(120), 
    PRIMARY KEY (id), 
    UNIQUE (email)

Deploy to Render

Create two files, and render.yml, in the root of your project.

Append the following content to

#!/usr/bin/env bash
# exit on error
set -o errexit

pip install -r requirements.txt

inspira migrate

In this script, we install the dependencies and execute the migrate command to create the tables.
Ensure that the script is set as executable before committing it to Git.

$ chmod a+x

Include the following in render.yml:

  - name: mydb
    databaseName: mydb
    user: mydb

  - type: web
    name: inspira_app_on_render
    runtime: python
    buildCommand: "./"
    startCommand: "gunicorn main:app -k uvicorn.workers.UvicornWorker"
      - key: DATABASE_URL
          name: mydb
          property: connectionString
      - key: SECRET_KEY
        generateValue: true
      - key: WEB_CONCURRENCY
        value: 4

Log in to your Render account. Navigate to Blueprints and choose the repository that contains the render.yaml file.

Great job!
Your Inspira application is now up and running on Render with a PostgreSQL database.
