# specification for the database, the scheduler # Create a docker-compose file with the container # Save environmental variables needed by Airflow in a separate # If an 'event not found' error arises, see # Create the directory structure for Airflow # Replace this with the directory that you want Make sure you replace everything that is signaled that needs replacing. If you’re here for the code, here’s the summarized versions. If you don’t have docker and docker-compose installed, follow this tutorial for docker and this one for docker-compose for installing both. That, without having to install anything other than Docker on your local computer. At the end of this tutorial we’ll have a very simple python program that runs every minute of every single day setup on Airflow with email warning whenever this program fails. Airflow is not particularly easy to install so let’s get to the point. Interested? See this.Įnough of definitions. It is in fact a cron-like system but it has other stuff like automatic email warning when your task fails, detailed logs, scaling thousands of tasks within a cluster and an infrastructure for creating dependencies between tasks. This tutorial extends most internet tutorials on Airflow to deploy a full-fledged example using Docker in the least amount of code possible.įor the sake of not repeating content on the internet, I’m gonna limit my definition of Airflow to this: it’s a way of repeating a program in a given interval of time, like within a specified schedule. However, I’m interested in doing the above without much hassle, meaning that I don’t want to spend 2 hours installing Airflow, dependencies, PostgreSQL, and so on.
AIRFLOW DOCKER HOW TO
There’s a bunch of tutorials out there on how to deploy Airflow for scaling tasks across clusters.
