Run Your Flask Regularly Scheduled Jobs with Cron

A common need of web applications is to have a periodically running task in the background. In this video I'm going to show you what I believe is a very robust implementation that is based on the Flask CLI and the cron service.

I have several servers in production using some sort of queue-based systems to perform tasks in the background. They work well but this is by far the most easy and robust method I have tried. You can access to the environment and the database as you are running the server. My new standard. Thanks Miguel for sharing this knowledge!

Dude you're the best. I've learned so much from your Flask tutorial. I get paid to build apps now thanks to your guides!

I have recently found your channel and I didn't know you had been uploading videos because I only checked your playlist! Now, I have so much to watch and learn from! Thanks!

You are always my #1 Source when i have some problems with flask!

Did i implement my own freaking cli controller before seeing this video? Perhaps!
Was the "get app context" part confusing? Definitely.
Will i throw most of it under the bus and do a lot of commits in the next view hours? Yeeees! XD

Thanks for the video <3

Miguel. Eres un grande! Te agradezco todos los videos. Leí tus dos libros. Flask web development y el mega tutorial. Uso flask en el trabajo y me siento muy cómodo. Me gustaría saber tu opinion de flask con zappa para aws lambda. Muchos saludos y gracias nuevamente.

Very informative, thank you! If I want to deploy this remotely (ex. to Elastic Beanstalk) does the Cron job spin itself up if it exists in my app directory, or would I need to do some additional configuration on whatever host I am deploying to?

You are the monty python sorcerer <3

Thank you Miguel but don't you need to specify something like "export FLASK_APP=flasky.py" for the flask cli commands to be accessible.?

what happens if i want to add job dynamically? for example, i have an API receiving a requests, then after 5 sec i want to update the database with this request?

if i have 50 + background job where i will write the code in flasky.py or how i manage in in a seperate blueprint and run it with well structure
