![]() We like to help people get started with our Airflow and have written a bit of content for it. This is the method we use to run other languages like Scala and JavaScript via Airflow.įeel free to reach out via email if you'd like to discuss more or have questions - taylor astronomer.io. DockerOperator - If the setup requires more complex things to be installed, you can use the DockerOperator and build out a simple Python Docker image e.g. That's pretty simple if it satisfies your requirements, but it's not a foolproof solution if your reason for being on 2.7 is complex or some system-level dependency that requires more.ģ. dockerfile: Dockerfile and then write this to your Dockerfile. You can run multiple Python versions mixed using the PythonVirtualenvOperator to run the other tasks in dedicated 2.7 etc virtual environments. image: apache/airflow:x.x.x in your docker compose you want to set this to. PythonVirtualenvOperator - Then, if upgrading your 2.7 code to 3.6 is an option, I would if that's a hurdle. PythonOperator - Assuming you're running Airflow on 3.6, you can run your 3.6 functions with the normal PythonOperator.Ģ. tl dr - Airflow can support running multiple Python versions.ġ. The following section contains errors you may encounter when using the Docker container image in this repository.That's definitely a good question, and one that I don't think is clearly addressed in the docs (so I might take the opportunity to turn this into a little blog post later). To learn more, see Managing Python dependencies in requirements.txt. If a library is not available in the Python Package Index (), add the -index-url flag to the package in your requirements/requirements.txt file.You can extend and customize the image according to your requirements and use it in your own deployments. Paste to Dockefile code below: FROM apache/airflow:2.1. We recommend adding libraries to this file, and running locally. Airflow has an official Dockerfile and Docker image published in DockerHub as a convenience package for installation. Put Dockerfile, docker-compose.yaml and requirements.txt files to the project directory. A requirements.txt file is included in the /requirements folder of your local Docker container image.How do I add libraries to requirements.txt and test install? Simply set the relevant environment variables in. This page describes the steps to install Apache Airflow Python dependencies on your Amazon MWAA environment using a requirements.txt file in your Amazon S3. To learn more about AWS environment variables, see Environment variables to configure the AWS CLI and Using temporary security credentials with the AWS CLI. You can set AWS credentials via environment variables set in the docker/config/.env.localrunner env file.To learn more, see Amazon MWAA Execution Role. To setup aws connection for Airflow locally see Airflow | AWS Connection ![]() You can setup the local Airflow's boto with the intended execution role to test your DAGs with AWS operators before uploading to your Amazon S3 bucket.Can I test execution role permissions using this repository? The following section contains common questions and answers you may encounter when using your Docker container image.
