Celery and Gunicorn on Clever Cloud

Deploy this application using Celery and Gunicorn. To follow this tutorial, you need a Clever Cloud account and Clever Tools:

npm i -g clever-tools
clever login

You can also install Clever Tools with many packages managers.

Create resources

Create and configure a Python application:

git clone https://github.com/CleverCloud/celery-gunicorn-example
cd celery-gunicorn-example

clever create -t python
clever env set CC_PYTHON_BACKEND "gunicorn"
clever env set CC_PYTHON_MODULE "app:server"
clever env set CC_PRE_RUN_HOOK "bash workers.sh"

Deploy the application

Everything is now ready, just deploy the application and open it:

clever deploy
clever open

Usage

You can now use the application by making a GET request to the following URL:

https://<your-app-url>?text=This%20is%20a%20demo

You can also add operations to the request by adding the following parameters:

• reverse: reverse the text
• uppercase: convert the text to uppercase
• lowercase: convert the text to lowercase
• repeat_count: repeat the text a number of times specified

For example, to reverse the text, you can make a GET request to the following URL:

http://<your-app-url>?text=Hello%20world!&reverse=true

You can also combine multiple operations:

http://<your-app-url>?text=Hello%20world!&reverse=true&uppercase=true&repeat_count=3
