set up with Flask amp RedisThis tutorial was originally posted on SigNoz Blog and is written by Ezz Celery worker is a simple flexible and reliable distributed system to process vast amounts of messages while providing operations with the tools required to maintain such a system In this tutorial we will learn how to implement Celery with Flask and Redis Before we deep dive into the tutorial let s have a brief overview of Celery workers What is a Celery worker Celery is a task management system that you can use to distribute tasks across different machines or threads It allows you to have a task queue and can schedule and process tasks in real time This task queue is monitored by workers which constantly look for new work to perform Let s try to understand the role of a Celery worker with the help of an example Imagine you re at a car service station to get your car serviced You place a request at the reception to get your car serviced MessageYou place a request at the reception to get your car serviced This request is a message TaskServicing your car is the task to be executed Task QueueLike yourself there will be other customers at the station All the customer cars waiting to be serviced is part of the task queue WorkerThe mechanics at the station are workers who execute the tasks Celery makes use of brokers to distribute tasks across multiple workers and to manage the task queue In the example above the attendant who takes your car service request from the reception to the workshop is the broker The role of the broker is to deliver messages between clients and workers Some examples of message brokers are Redis RabbitMQ Apache Kafka and Amazon SQS In this tutorial we will use Redis as the broker Celery as the worker and Flask as the webserver We ll introduce you to the concepts of Celery using two examples going from simpler to more complex tasks Let s get started and install Celery Flask and Redis PrerequisitesTo follow along with this tutorial you need to have a basic knowledge of Flask You don t need to have any knowledge of Redis however it would be good to be familiar with it Installing Flask Celery and RedisFirst initiate a new project with a new virtual environment with Python and an upgraded version of pip python m venv venv venv bin activate pip install upgrade pipand install Flask Celery and Redis The following command includes the versions we re using for this tutorial pip install celery Flask redis Running Redis locallyRun the Redis server on your local machine assuming Linux or macOS using the following commands wget tar xvzf redis stable tar gz rm redis stable tar gz cd redis stable makeThe compilation is done now Some binaries are available in the src directory inside redis stable  like redis server  which is the Redis server that you will need to run and redis cli  which is the command line client that you might need to talk to Redis To run the server globally from anywhere on your machine instead of moving every time to the src directory you can use the following command make installThe binaries of redis server are now available in your  usr local bin directory You can run the server using the following command redis serverThe server is now running on port the default port Leave it running on a separate terminal We would need two other new terminal tabs to be able to run the web server and the Celery worker later But before running the web server let s integrate Flask with Celery and make our web server ready to run Integrating Flask and CeleryIt s easy to integrate Flask with Celery Let s start simple and write the following imports and instantiation code from flask import Flaskfrom celery import Celeryapp Flask name app config CELERY BROKER URL redis localhost celery Celery app name broker app config CELERY BROKER URL celery conf update app config app is the Flask application object that you will use to run the web server  celery is the Celery object that you will use to run the Celery worker Note that the CELERY BROKER URL configuration here is set to the Redis server that you re running locally on your machine You can change this to any other message broker that you want to use The celery object takes the application name as an argument and sets the broker argument to the one you specified in the configuration To add the Flask configuration to the Celery configuration you update it with the conf update method Now it s time to run the Celery worker Running the Celery workerIn the new terminal tab run the following command venv celery A app celery worker loglevel infowhere celery is the version of Celery you re using in this tutorial with the  A option to specify the celery instance to use in our case it s celery in the app py file so it s app celery and worker is the subcommand to run the worker and  loglevel info to set the verbosity log level to INFO You ll see something like the following Let s dive into the logic inside your Flask application before running the web server Running the Flask web serverLet s first add the celery task decorator with the task  method and wrap the function that we want to run as a Celery task to that decorator celery task def add x y return x ySo this simple add function is now a Celery task Then add a route to your web server to handle the GET request to the root URL and add a pair of numbers as the parameters to the add function app route def add task for i in range add delay i i return jsonify status ok Note Don t forget to import the jsonify function from the flask module to be able to return JSON data Now run the web server with the following command flask runWhen you check the localhost  URL in your browser you should see the following response status ok Note that this response is not instantly shown on your browser That s because the Redis server listens to the client and enqueues the task to the task queue of that add task function The Celery worker then has to wait for every task before it starts execution This demonstrates how Celery made use of Redis to distribute tasks across multiple workers and to manage the task queue You can find the entire code sample for this tutorial at this GitHub repo ConclusionIn this tutorial you learned what a Celery worker is and how to use it with a message broker like Redis in a Flask application Celery workers are used for offloading data intensive processes to the background making applications more efficient Celery is highly available and a single Celery worker can process millions of tasks a minute As Celery workers perform critical tasks at scale it is also important to monitor their performance Celery can be used to inspect and manage worker nodes with the help of some terminal commands If you need a holistic picture of how your Celery clusters are performing you can use SigNoz an open source observability platform It can monitor all components of your application from application metrics and database performance to infrastructure monitoring For example it can be used to monitor Python applications for performance issues and bugs SigNoz is fully open source and can be hosted within your infra You can try out SigNoz by visiting its GitHub repo If you want to learn more about monitoring your Python applications with SigNoz feel free to follow the links below Python application monitoringDjango
