You can also define connections via environment variables by prefixing them with AIRFLOW_CONN_ - for example for a connection called "postgres_master". The general rule is the environment variable should be named AIRFLOW_, for example AIRFLOW_CORE_SQL_ALCHEMY_CONN sets the sql_alchemy_conn config option in the section.Ĭheck out the Airflow documentation for more details

It's possible to set any configuration value for Airflow from environment variables

Optionally install Extra Airflow Packages and/or python dependencies at build time :ĭocker run dataopssre/docker-airflow2 python -c "from cryptography.fernet import Fernet FERNET_KEY = Fernet.generate_key().decode() print(FERNET_KEY)" You can use the helm chart release in this repository, see here to deploys airflow2 to a Kubernetes cluster.

Improve current script to only take into account Airflow environment variables.

Disactive by default the login screen in Airflow 2.

Thus puckel's airflow startup script is usefull. With Kubernetes you can resolve Airflow scablity issue by using uniquely KubernetesPodOpetertor in your dags, then we need zero computational power for airflow, it serves pure purpose of scheduler, seperate scheduler and webserver into two different pods is a bit problematic on AWS EKS cluster, we want to keep dags and logs into a Persistant volume, but AWS has some limitation for EBS volume multi attach, which means webserver and scheduler pod has to be scheduled on the same EKS node, it is a bit annoying. Nevertheless, puckel's image is still interesting, in the market none of providers offer an Airflow run with LocalExecutor with scheduler in one container, it is extremely usefull when to deploy a simple Airflow to an AWS EKS cluster. This repo is forked form puckel/docker-airflow, the original repo seems not maintained.Īirflow is been updated to version 2 and release its official docker image, you can also find bitnami airflow image.

Airflow 2.0 github code#

If you follow the stack trace you will get to this chunk of code that leads to the error because the association_proxy has a ' clause_element' attr, but the attr raises the exception in the error when called. I do not have deep knowledge of SQLAlchemny so I am not sure why this change was made, but it results in it the error I'm getting. The issue seems to have been introduced with Airflow 2.2.0 (pr: ), where the TaskInstance.execution_date changed from being a column to this association_proxy. However, I do not think this is a sqlAlchemy issue. I am using SQLAlchemy version 1.2.24 but I also tried with version 1.2.23 and encountered the same error.
